The correct height of the computer desk. Are other sizes important? Once again about safety: how to protect children from injury

Computer desk not only hides massive computer parts (processor, subwoofer, etc.) and numerous wires, but at the same time provides enough space for disks, books and other small things.

There are enough desks for a computer in the store roads. Independent making a table will save a lot monetary funds and will not take much time.

Types of computer tables

Options designs a lot of tables for the computer. straight and angled, compact tables and entire ensembles, including, in addition to the computer desk itself, all kinds of lockers, nightstands, shelves.

There are several types special tables, destined to install on them. laptop, ultrabook, netbook.

Very relevant for small apartments Options for transforming computer tables too varied: table-cabinet, table-cabinet.

Yes, narrow closet does not take up much space, and, if necessary, turns into full-fledged computer desk, and all constituents computers are in place, and you do not have to clean them every time.

What can you make a table for a computer

Great option - computer from wood. You can also use other traditional furniture to create materials:

• laminated sheets
• MDF;
• plastic;
• metal;
• glass.

Note! Metal computer table with glass top- This optimal solution for high-tech interiors.

Calculation of the size of a computer desk

Difficulty in sizing corner computer desk, so first consider just this option.

Corner table dimensions

Factors that affect the size of the table:

• Tabletop width. The minimum width of the worktop is 50 cm (500 mm). Optimal size- 60 cm (600 mm).
• Section width(which are the table supports). For every table different width sections. If it is a processor tray, 20–25 cm (200–250 mm). If the tray with drawers or door is 45–60 cm (450–600 mm).
• corner depth(where the person is located). Minimum size- 50 cm (500 mm), optimal - 60 cm (600 mm).

General table dimensions are calculated based on the above sizes.
Side overlaps - 5 cm (50 mm).

Minimum table size

• table top width 50 cm;
• corner depth - 50 cm;
• section width - 20 cm and 45 cm;
• 5 cm + 20 cm + 35.4 cm + 50 cm = 110.4 cm - length of one wing table;
• 5 cm + 45 cm + 35.4 cm + 50 cm = 135.4 cm - the length of the second wing.

Optimal table size

• table top width 60 cm;
• corner depth - 60 cm;
• section width - 25 cm and 50 cm;
• 5 cm + 25 cm + 42.4 cm + 60 cm = 132.4 cm - length of one wing table;
• 5 cm + 50 cm + 42.4 cm + 60 cm = 157.4 cm is the length of the second wing.

Straight table dimensions

Dimensions direct computer desk calculated similarly. To do this, you need to know the width tray(or trays), working width places(50–60 cm) and overlaps(5 cm on each side).

Minimum table size

• with one tray:
  5 cm + 5 cm + 20 cm + 50 cm = 80 cm;
• with two trays:
  5 cm + 5 cm + 20 cm + 45 cm + 50 cm = 125 cm.

Optimal table size

• with one tray: 5 cm + 5 cm + 25 cm + 60 cm = 95 cm;
• with two trays: 5 cm + 5 cm + 25 cm + 50 cm + 60 cm = 145 cm.

Height table varies from 70 to 76 cm.

Note! It is not recommended to make a table above or below the prescribed dimensions, as this will lead to an incorrect body position when working at a computer, the development and exacerbation of diseases of the back and spine.

Drawing of a computer desk with dimensions

Materials and tools

On one's own do computer desk is not difficult. To do this, stock up materials and tools that will be needed in the manufacturing process and assemblies.

In addition to the base material (chipboard, MDF) you will need:

• glue PVA;
• pair guides for a sliding shelf (length - 30 cm);
• self-tapping screws or confirmations(furniture screws);
• dowels for furniture - 4 or 6 pcs.

You will also need the following to work. instruments:

• the pencils square;
• jigsaw;
• drill;
• screwdriver;
• hexagon;
• roulette;
• sandpaper;
• drill for confirmation.

Important! When cutting table parts from laminated chipboard with extreme caution, rounded parts should be cut with an electric jigsaw so that there are no chips.

Straight computer desk

Consider the manufacture of simple models.

Step 1. Cutting and processing wooden details for the future table:

• side racks 735 x 465 mm - 2 pcs.;
• central rack 735 x 380 mm - 1 pc.;
• back wall 1090 x 290 mm - 1 pc.;
• countertop 1200 x 580 mm - 1 pc.;
• internal shelves 450 x 250 mm - 2 pcs.;
• retractable shelf 830 x 380 mm - 1 pc.

Step 2 in the side and central on the rack we make holes for confirmations: 4 for each shelf. We strengthen bottom shelf.

Step 3 Fasten in the same way top shelf.

Step 4 We fasten back wall.

Step 5 We fasten the second sidewall with the help of two confirmations. From the front it will look like this:

Step 6 Marking a place for guides and proceed to fix them. When choosing or making sliding shelves, you should remember about thickness guides (1 cm on each side).

Step 7 Fasten guides to shelf.

Step 8 Drilling small holes in lateral racks (under the dowels of the tabletop). Similar holes drilled into the table top. You do not need to drill through the countertop, but the depth should be not less than 25 mm.

Step 9 Lubricated dowels glue PVA, insert them into the ends frame table.

Step 10 We put the tabletop on top and insert the dowels into grooves.

On the surface of the table, also on dowels, you can install shelves with drawers for small things, notebooks and disks.

Corner computer desk

Corner tables for the computer also come with superstructures and without add-ons.
Length wings:

• minimum - 110/135 cm;
• optimal - 132/157 cm;
• maximum - 166/200 cm.

Step 1. Draw and cut everything details future table. If for the manufacture of the table are used not laminated materials, antiseptic.

Step 2 Cut out countertop. We collect side racks with shelves (confirmations). Right section (which larger size ohm) can be with retractable drawers or with one door.

If a section is made with boxes, then on internal side of the side walls are pre-attached guides. Boxes are collected, which are also fasten guides.

Step 3 With the help of confirmations, he gathers angular table support.

Step 4 Attached to it is a rectangular frame with guides and a retractable shelf for keyboards.

Step 5 in the tabletop, lateral racks and corner support holes are made under dowels(2 pcs on each side and 1 pc on each side of the corner of the corner support).

Step 6 Dowels pre-lubricated PVA, are inserted into the side posts and corner support.

Step 7 Installed countertop.

The sections at the back are closed with walls made of Fiberboard. We cover the finished table varnish or paint.

Computer table decoration

If in the manufacture of the table are used laminated wood sheets, then any special finishes not required. Process only visible ends details.

For this, a special edge ribbon. It is made from different materials and there are different colors.

The edge gives the product a finished and aesthetic appearance, and also prevents the release of harmful to humans from chipboard formaldehyde. On the ends of the parts, the tape is glued with iron.

The choice of a suitable desk is, of course, an important process, because not only the performance of the person sitting, but also health will depend on the correct decision. This is especially true when it comes to a child and his developing body.

What standards are accepted

The health of a person working at a computer requires special attention. When choosing, you should consider all factors, from the size of the monitor to the height of the desk. Incorrect calculations can lead to problems with the spine and visual impairment. In addition, if a person working at a computer feels discomfort, he will quickly get tired and, as a result, his performance will drop.

Exist "Modulor"- a system according to which standard proportions are revealed for all modern furniture, including the height of tables. This parameter is very important, because it determines the position of a seated person. The one sitting at a low table stoops and leans forward, and the one sitting at a high table is forced to raise his head up, which, of course, is erroneous.

Do not forget that the correct position of the human body implies a straight back, loose forearms and no tension in the shoulder girdle. In addition, the legs should be on the floor and bent at a 90-degree angle.

How many centimeters high?

Based on average growth ordinary person, which is 175 cm, the creator of the Modulor system, Le Corbusier, came to the conclusion that the height of the desk should be between 70 and 80 centimeters. Thus, the standard value is 75 cm in the case of a male height of 175 cm and a female of 162 cm. This formula is correct for the bulk of people with typical height. Naturally, there are exceptions if a person is significantly below or above the standard.

If your height is beyond the standards, then, firstly, you can change the height of the seat (usually modern models are adjustable). Don't forget to add a kickstand to keep your knees bent at a 90 degree angle. Secondly, you can make a table according to custom order. Thirdly, it is possible to choose a table with an adjustable table top height.

Are other sizes important?

Comfortable work is impossible without the correct determination of the width of the tabletop, that is, the distance between its left and right edges. The minimum size is 60 cm, but it is recommended to choose models with larger values. The correct depth of the table for an adult is from 35 to 60 cm. The space where your legs are (the length between the legs or pedestals) should be at least 52 cm. It is also important to determine such parameters as the width and height of the chair. According to Le Corbusier's calculations, for comfortable work The width of the seat must exceed 40 cm, and the height must be between 42 and 48 cm.

Why is an adjustable table good?

Adjustable models are usually bought for children. Such tables can be used for a long time, despite the fact that the growth of the child will change. The essence of such furniture is as follows: it is possible to raise or lower the tabletop due to retractable legs, as well as change its slope. These tables can be wooden, plastic or with metal frame. Very often, the design is combined with a chair, the height of which can also be adjusted. In fact, the design is a school desk.

The adjustable table for adults will become great solution for families in which people of different heights are forced to use the same workplace.

How to choose the right desk?

Having decided to buy a desk, you must first decide which model you need - a regular desk or a computer one. In the second case, make sure that the item has special places for the system unit, speakers, keyboard and wires. Next, the cost issue needs to be addressed. The price of a future purchase depends on the following factors:

• Where the furniture is made and whether it is under the "cap" of the brand. Tables made in Russia are usually cheaper than foreign ones. Also keep in mind that sometimes little-known companies can surprise you with high quality coupled with low prices.
• Material. Products made of plastic, chipboard or MDF cost much less than solid wood models.
• Dimensions. The smaller the table, the lower its price.
• Decor. The presence of fittings significantly affects the final cost of furniture. The higher the quality, the more fittings and the more intricate the design, the more more money you will have to pay.

For a child

The main thing to remember when choosing a table for a child is the requirements of his health. Adhere to the following rules:

• The width of the countertop should be at least 100 cm, and the depth should be between 60 and 80 cm.
• For the legs, the child should have a space of approximately 50 * 45 cm.
• Take into account the difference between the height of the table and the chair: this parameter should be 20-24 cm.

When buying a table, take the baby with you to the store and ask him to sit down at the selected model. Look at the elbows and legs: the first should be loose, and the second should be bent at a right angle and stand firmly on the floor. Try to leave a gap of 10-15 cm between the table top and your knees.

Also, from the countertop to the eyes of your child, you must maintain a distance equal to the distance between his elbow and fingertips. In addition, there are several more recommendations for choosing a workplace for a student. Consider the interests of the child and make sure that the table is roomy: during execution homework the student should calmly place textbooks, notebooks, stationery and other necessary items.

Models of children's tables are different, you can choose a design with a design that meets the interests of your child:

• Standard design rectangular shape with multiple boxes. The price depends on the material, but as a rule, these are the cheapest designs.
• A computer desk with the necessary details for a computer: keyboard panels, space for a monitor, holes for wires and others. Such models are made of glass, wood and furniture panels.
• L-shaped table, which allows you to combine both a place for a computer and a space for doing homework.
• Transformer (adjustable), which makes it possible to change the height of the table when the child grows. Sometimes such models are orthopedic or folding.

Do not buy an expensive table for a student, children are unlikely to be able to leave it in its original state and not stain it with paints or pens. Also watch out for security: certain types plastic can be toxic and have a strong odor, allergic besides, they quickly become unusable. Never skimp on quality.

For an adult

About how to correctly calculate the dimensions of the desk, it was said above, however the choice of a workplace for an adult largely depends on its purpose, which determines both the material, and the functionality, and the size of the structure:

• Large tables are the most expensive models. Usually made from precious woods High Quality, they are decorated with leather, carvings and designer fittings and complemented by numerous drawers and coasters.
• Medium tables can be made from solid wood or furniture boards. Their price depends on this. Such tables perform the same functions as large ones, but due to the smaller size and different material, they win in cost.
• Small tables, as a rule, are bought for small rooms in which it is important to save space. They are cheap, quick to assemble, but don't have drawers or shelves.

When choosing a desk, also pay attention to the material of manufacture, spaciousness, your needs (for example, if you have poor eyesight, then it is not recommended to purchase a table closed design) and the place where the furniture will be placed. Main materials for tables: MDF, chipboard, wood, glass or plastic. Determine the number of shelves and drawers depending on your needs: the more there are, the higher the functionality of your design will be.

When choosing fittings, give preference to steel alloys.

Overview of popular models

Model "Mikke", Ikea

The writing desk is made of chipboard, MDF and fibreboard, available in white and dark brown. The model has a laconic neutral design, which allows it to fit into any interior. To increase the working space, you can add a table with cabinets and a variety of modules for things. There is a hole for wires at the back, that is, the table also acts as a computer one, and the drawer is equipped with a special design that prevents it from falling out. The surface is covered with acrylic paint.

Hemnes model, Ikea

Surface standard table finished with white stain, but the furniture can also be presented in light brown and dark brown. The table is made of solid pine, which increases its ecological properties. Computer wires and extension cords can be hidden on a special shelf under the tabletop. There are two drawers and two closed shelves. Classic design.

A desk is an almost indispensable piece of furniture in any apartment. And no matter how we think that this furniture is a relic of the past, we categorically disagree with this. Practically in every house this piece of furniture is successfully used and finds its application. Whether it's a student's or student's room, an office business man or businesswoman workplace. In large offices, an expensive desk is also an indicator of a certain status of its owner.

There are no critical differences between a computer and a desk, as such. But still they are. Let's talk about some of them:

• stand or compartment system unit. Main distinguishing feature computer furniture. The desk is missing as an extra and unnecessary detail;
• speaker stands. Small shelves on the superstructure. Most often located on the sides of it. There are in almost all computer and not in any desk;
• Pull-out shelf for the keyboard, located under the tabletop. Highly handy item for computer furniture. If in this moment You do not need to print anything, it just slides in and does not take up space. On the desk is not needed in principle;
• cable channel and holes for wires. Even if you are working on a laptop while sitting at your desk, wires are clearly not needed. The charger is connected to the laptop, as a rule, at night, and during operation, the mobile gadget is powered by a battery and does not need a power cord;
• tabletop leather trim. In exclusive and expensive furniture for writing, this technique is often practiced. It is not only beautiful, but also practical. In computer furniture models this species finishing is not applied;
• monitor mount. In some models of computer tables, special fasteners are made on the table top, in which the screen of the “smart machine” is fixed. In products for writing, they are absent as completely useless.

But despite many design differences, these interior items are undoubtedly similar. A special similarity can be observed between and their computer "brothers". Yes, and the dimensions of the tables are few differences. In general, based on all the qualities of furniture for writing and a computer, we can conclude that they are close relatives and do not differ very significantly. And in many ways they are even similar.

Product parameters

For adults

Let's talk about parameters desks. In some articles of the section, we thought about the size of desks in the context of the convenience of placing them in an office or working area. But the conversation about dimensions tied to anthropometric data did not come up, or this topic was mentioned in passing. And it is no less important than the parameters of furniture in the interior. Let's dwell on it in more detail.

The comfort of working at a desk largely depends on the size of the human body and right choice furniture options. According to the "Modulor", which was designed by the great French-Swiss designer and architect Le Corbusier, special proportions are revealed. Everything is done according to them modern furniture including desks. Only one single parameter affects the comfort of seating and health - the height of the table.

Based on the average height of an ordinary person, Le Corbusier deduced that the standard height of a desk should not be less than seventy centimeters, but not more than eighty, with rare exceptions. But this special case, rarely in our life there are giants and very small people. The proportions are calculated for the bulk of people living on Earth. According to them, desks are made. The average height of all the inhabitants of our planet, according to which the height was considered, is one hundred and eighty-three centimeters.

For comfortable work, such a parameter as the length of the table is also important. The length of the table is the distance from its left edge to the right edge relative to the person sitting at the workplace. The minimum length of the countertop must be at least sixty centimeters. This minimum dimension is necessary for the comfortable work of one adult. We emphasize the word minimum in this statement, it is desirable that the length of the workplace be longer.

The distance for the legs (that between the legs or pedestals of the desk) must be at least fifty-two centimeters.

An important role in determining a comfortable pastime at the desk is played by the width and height of the chair. They are also calculated in Modulor. The width of the work chair or armchair must be at least forty centimeters with a height of forty-two to forty-eight centimeters, respectively.

But these are all dimensions of furniture for adults.

For a child

But how to choose the right desk and chair for him for a child? Let's describe the main criteria:

• when seated at a table, the feet are completely on the floor, and a right angle is formed between the lower leg and thigh. If the angle is obtuse - the chair is too high, the angle is sharp - pick up the furniture higher;
• determine the depth of the chair as follows - the seat should not dig into the popliteal joints;
• the distance between the knees and the tabletop should be ten to fifteen centimeters;
• the correct distance from the eyes to the top of the table should be equal to the distance from the fingertips to the elbow of your offspring.

If you have already managed to buy a desk for yourself, but not for your child, then before you run to the furniture store, we recommend watching the following video:

Where is the best place to place this item?

When purchasing a desk, the question often arises: “How and where is it better to place it?”. Many are guided by considerations of personal taste, someone sets up a table based on convenience for work and proper lighting, and some are guided by the teachings of Feng Shui. And we will focus on all these aspects.

The desktop, according to Chinese teachings, should have not only a beautiful appearance and , but also excellent feng shui. Factors to be observed for this:

• you can not sit with your back to the window;
• do not sit opposite the door to the room;
• pay attention to the symbols of water (images, aquarium, indoor fountain or waterfall). They should not be behind. Place these symbols in front of your eyes or above your head;
• the larger the table, the better;
• obligatory order on the table. A tabletop littered with papers is not feng shui.

As Chinese philosophy teaches, if these factors are observed, the owner of the office, where the table is correctly installed, will be lucky in business and finances.

For health reasons, the table is set in front of the window, so that you sit facing the opening. Daylight should fall so that the shadow from the hand does not cover what you are writing.

And when artificial lighting it is important to ensure that it is not dimmer than sunlight. Ideally white, not yellow shade close to daytime. This is what ophthalmologists advise.

And of course, all of us have our own vision of the location of the table in the room. Here you can be guided by our advice, or you can put the furniture to your taste. As they say, the master is the master.

In more detail about the nuances of Feng Shui associated with the placement of desks, the following video will tell:

Points of sale and ways to save

The purchase question can be answered immediately. As we have repeatedly written in many of our articles about furniture, the easiest way is to buy furniture inexpensively, incl. and a desk in an online store: save money and time. Yes, and you can choose among a huge number of manufacturers without driving around furniture stores the whole city. In addition, online stores offer both photos, videos, and 3D models of products, so you can see everything to the smallest detail even better than live.

As for savings when buying a desk:

• brand and country of origin. Domestic tables are not an example cheaper than Italian ones. And less famous factory does not raise prices due to popularity. Although sometimes her products are much better;
• material. The simpler it is, the cheaper the table. Chipboard products are three times cheaper than solid wood furniture;
• dimensions. The smaller the desk, the more less material it took to manufacture, and, consequently, the price is lower;
• accessories. Various handles, hinges and drawer guides also have their price. The higher the quality, the more expensive the product.

Price abundance

Well, we finally got to price categories desks. There are not so many of them:

• . The most expensive type of tables. They are made, as a rule, and finished with carvings, inlays, leather. This furniture costs from 40,000 to 800,000 rubles. Pricing depends on the type of wood and manufacturer. Often performed in;
• medium. Made from both natural wood and wood-based materials. Moreover, the price of these categories of products will differ two or three times. The functionality of medium tables is the same as that of large ones, only they are cheaper and take up much less space. For which they are popular with the people. The price of this category is from 5000 to 35000 rubles;

The health of a person working at a computer is affected by many factors, one of which is the height of the table. An incorrectly calculated height of the product can cause diseases of the spine, as well as visual impairment. In addition, a person who feels discomfort when working at a computer desk consumes much more energy, and, therefore, quickly gets tired. In general, it is troublesome to have a table of improper height. Therefore, I propose to look into this issue in detail.

How should a person sit at a table?

Why does table height affect human health? Why not or? The fact is that it is the height of the table that can change the position of the person sitting behind it. Too much low table will make the user slouch and lean forward, and too high will make the user lift their head up and feel discomfort.

The optimal position of a person sitting at the “correct” computer desk is a flat back, forearms lie freely on the table top, without lifting the shoulder girdle. As a rule, the countertop is at the level of the solar plexus. By the way, it should be noted that sitting on a chair, the legs should be on the floor and be bent at an angle of 90 degrees.

But how to achieve such a position? Are there any standards or formulas? To be honest, I have own opinion on this point, which will be discussed below. But first, I bring to your attention the official standards for calculating the height of the table.

How to calculate the height of a computer desk

So, we must immediately say that:

There is a standard height of a computer desk, which is 750 mm.

Where did it come from, and how was it calculated? Everything is very simple! The fact is that according to statistics, the average height of a man in our country is 175 cm, women - 162 cm. It is for this height that the standard table height is calculated - 75 cm (750 mm).

If, however, your height is lower or higher, then you can calculate the height of the computer desk individually for yourself using the following formula:

Your height * 75 cm / 175 cm = table height

For example, your height is 182 cm, then optimal height computer desk will be calculated as follows:

182 cm * 75 cm / 175 cm = 78 cm

However, often in the house at the computer desk, not one person works, but several family members. And most often, these are people of different heights. So you will make yourself a table for your height of 192 cm, but how will your father-in-law, who is 160 cm tall, or mother-in-law - 155 cm, feel behind it?

Okay, father-in-law! You can always agree with the father-in-law. But here's the mother-in-law ... How to convince the "mother" that bouncing while working at the computer and hovering in flight banging on the keyboard is comfortable? I hope you all understand that this is simply unrealistic. And therefore, here is my personal point of view regarding the calculation of the height of a computer desk.

Choose a standard height whenever possible

From the title, you probably guessed that I recommend, if possible, choosing the standard table height - 750 mm. By the way, in our site all models have a height of exactly 750 mm. Now I will explain why.

Look, if your height is 182 cm, then the calculated height of the table should be: 78 cm. We have a difference of 3 cm from standard height table. In principle, in my opinion, an error of up to 3 cm is quite acceptable. Therefore, the allowable user height range is from 168 cm to 182 cm. That is, for people whose height is within this range, a computer desk with a standard height of 750 mm is quite suitable. And it is precisely this height that manufacturers make tables office furniture- since, it is universal for most of the inhabitants of our country.

Solutions for non-standard situations

But what about those who are 155 cm or 195 cm tall? After all, there are many such people. Do they have to suffer all their lives, sitting at uncomfortable tables? Of course not. Here I personally see three options for solving the problem:

1. 1. You can achieve a comfortable position by changing the height of the chair. Modern office chairs allow you to adjust the height of the user's position relative to the table. So why not take advantage of this? But this option is suitable for people whose height is below 168 cm. You can simply adjust the height of the chair, setting for yourself the most comfortable position in height relative to the top of the table.

   However, I want to note that if you raise the chair higher, then your legs will no longer be bent at the knees at 90 degrees. Therefore, you definitely need to install a low stand under your feet. So you can ensure yourself a comfortable position at a computer desk of standard height. But this method, I repeat once again, is suitable for people of short stature. But what about high PC users? And for tall ones, perhaps the second or third option is suitable. Let's go to them.

2. 2. Make a table of the proper height for an individual order. This method is a good solution for tall people, and it is also suitable for those who are under 168 cm tall. You have the calculation formula. So, I think you can quickly decide on the height of a computer desk, making it yourself or to order. And finally, the third way.
3. 3. Make a table with adjustable tabletop height. Desks with adjustable height are popular with furniture manufacturers for schoolchildren today. The child grows, and with him his desktop “grows” - this is the right and thoughtful approach. Actually, we can take it into service by designing a computer desk at which a short mother-in-law with a height of 155 cm and her favorite son-in-law with a height of 192 cm will work. It can be made possible to adjust the height of the tabletop to the height of each user.

   I would not call this method ideal - it has a number of disadvantages. For example, the possibility of designing some models of extensions for such tables becomes more complicated. Also, to change the height of the countertop, you will have to remove everything from the table. However, it is possible that this option may be the most successful solution for someone.

So, we considered the issue of calculating the height of a computer desk. I hope I was able to present the information intelligibly and clearly. It remains the case for small things - to make a decision in favor of one or another option. But you must do this yourself. I wish you all good luck! I'm sure you will succeed!

The organization of workplaces for staff is one of the key issues in office equipment. They must be comfortable and meet the requirements.

The main elements of the modern workplace of any office employee are office tables, chairs, and computers. It should be remembered that, in accordance with sanitary standards, the distance between office tables should be at least two meters, while the area per workplace should be at least 4.5 m² (at least 6 m² if a person works at a CRT monitor). Workplace should be organized in such a way that the employee has the opportunity to change the working posture and not create muscle overload. Proper organization jobs for 90% depends on how well selected office tables and office chairs.

What requirements do they have to meet? should be designed in such a way that everything necessary for work is conveniently placed on their surface. Tables can be either fixed or adjustable height. working surface. Adjustable height should vary from 680 to 800 mm., and the mechanism for its adjustment should be easily accessible, easily controlled, and have a secure fit. If the working surface is unregulated, then its height should be 725 mm. As for the dimensions of the working surface of office tables, the depth should be at least 600 (800) mm, width - at least 1200 (1600) mm. In addition, the edges and corners of the working surface of the office desk should not be sharp. Legroom at the office desk should be at least 600mm high and at least 500mm wide, and at least 450mm deep at knee level and at least 650mm at knee level. outstretched legs. The keyboard stand must be adjustable in height and allow the keyboard to be placed at a distance of 100-300 mm from the edge. Monitor screens should be 600-700 mm from the eyes, but not closer than 500.

Chairs of office workers should, first of all, maintain a rational working posture, allow it to be changed to reduce static muscle tension in the neck, shoulders and back, and also exclude the possibility of disturbing blood circulation in the legs. They should be chosen taking into account the height of the user, the nature and duration of his work.

Armchairs for employees must necessarily be equipped with a lifting and turning mechanism, and the angles of inclination of the seat and backrest must be adjustable in height and in the distance of the backrest from the front edge of the seat. To reduce static tension in the muscles of the arms, employee chairs are equipped with stationary or removable armrests, which can be adjusted in height above the seat and in the internal distance between them. It is especially convenient when the regulation of each position is carried out independently, easily, and securely fixed.

The seat surface of the chairs must have a width and depth of at least 400 mm. and, ideally, the ability to change the angle of the seat surface from 15° forward to 5° back is needed. The seat height must be adjustable between 400 and 550 mm. And the height of the backrest should be 300 (plus or minus 20) mm, and the width should be at least 380 mm. The backrest angle should be adjustable from 0° to 30° from vertical position, and the distance of the back from the front edge of the seat is from 260 to 400 mm. The length of the armrests should be at least 250 mm, the width - 50-70 mm, and their height above the seat - adjustable within 230 mm, while the internal distance - between 350 and 500 mm.

It is also important to place the furniture that makes up the workplaces of employees. Office tables should be placed so that computer monitors are oriented sideways with respect to light sources, and natural light fell on the left. If these are the workplaces of employees whose work is creative, requires a significant concentration of attention or high mental stress, then they should be isolated from each other by partitions.
