Distance from table to chair. Ergonomics. Optimal furniture sizes. What are the dimensions of the chair "Standard"

The importance of the size of the chair does not need to be proved - just try to sit on any uncomfortable model for at least 30 minutes. Incorrect body position almost immediately makes itself felt by unpleasant sensations in the back or joints. And what is the right one? If the chair fits perfectly in height, then both feet of the person sitting rest on the floor, while the bend of the ankle, knees and hip joint should be 90 °. Therefore, in order to choose a chair for height, it is enough to pay attention to two factors:

If the foot is not completely adjacent to the floor, you should look for a chair lower.
If the knees are raised too high, choose the option with a higher height.

Most often, chairs serve as an attachment to the table - dining, writing, etc. In this case, it is advisable to take into account one more rule: the comfortable distance between the seat and the edge of the tabletop is 30 cm.

However, it is impossible to give a universal answer to the question of size. By itself, standard height bar stool will be very different from the height kitchen stool. Therefore, we will try to analyze each case separately.

- What should be the height of the chair for the kitchen or living room? Traditional models are usually designed for standard height (165-175 cm), so the seat height of such chairs is about 40-45 cm. When choosing a single set, you should focus on the tallest member of the family - it is believed that too low a chair brings more discomfort.

- What should be the height of the bar stool? There are no clear rules here, because in any case, the legs of the seated person do not rest on the floor, but on the stand, or do without support at all. Nevertheless, there are several standards for the height of bar stools: models of about 60-70 cm are considered low, about 75-81 cm are medium, and 85-95 cm are high. They are convenient for almost everyone, except perhaps for children. In addition, bar stools are often equipped with height adjustment, a gas lift mechanism.

How to choose the height of the children's chair?

This issue deserves a separate consideration. Often parents prefer children's chairs with height adjustment. In this case, there is no need to frequently buy new furniture as the baby grows. However, there are chair seat height standards based on height:

With a child height of 90 cm, the height of the seat of the chair should be 22 cm.
With a height of 120 cm - 30 cm.
With a height of 140 cm - 37 cm.
With a height of 160 cm - 40 cm.

What matters besides height?

Other parameters of the chair also matter. For example, optimal width the seat is considered 50 cm - on such a chair it will be convenient for a person of almost any build. But the choice of furniture with armrests should be approached with caution: it can be uncomfortable for a full person to sit on such a chair.

The seat depth of the chair is usually about 40-45 cm. In order to understand if the model is right for you, do a little test. Optimal distance between the bend of the knees of the seated person and the edge of the seat should be 5-8 cm. The gap can be more, but not less, because in this case the edge of the chair will “crash” into the skin, you just have to sit a little deeper.

Choosing a chair "intuitively", not paying attention to its real parameters, it is very easy to make a mistake. And such a mistake can be quite expensive. After making sure that the model is uncomfortable, you will most likely start looking for a new one. Therefore, it is better not to waste money and time, but to immediately pick up chairs, taking into account all the important dimensional characteristics.

What should be the correct chair height for a kitchen table? What should be the table? You should not eat and work at the same table, and here's why - height and desktop height should be different. Consider the height of the kitchen table.

What is the most comfortable way to sit at the kitchen table? When it is too low, you will have to lean towards the plate; if it is an uncomfortable chair, the person sitting behind it will stoop.

How to choose the right height of the kitchen table and chair?

Many sellers say with confidence that the height of the kitchen chairs is standard and the tables too. But in practice, this is far from always the case, because people are inherently different, some have longer arms, some have shorter ones, and so on. In addition, the height of the furniture is calculated according to the average height. modern man- 165 cm.

I bought a table for the kitchen, and chairs in a standard store. But I don't feel comfortable sitting at this table. I began to understand why and realized that the height of the chair was not correct. How to choose the height kitchen chair for myself? And if everyone in the family is of different heights, you will have to purchase kitchen chairs with height adjustment, or kitchen table with adjustable table top.

The most comfortable are kitchen chairs with a wide seat and a reinforced ring under the seat. Of course, you can buy a height-adjustable kitchen chair with a back, but most often you want to buy classic wooden kitchen chairs.

The height of the kitchen chair and table according to GOST

The standard height of the kitchen table is 72-78 cm (from the floor to the top edge of the countertop). The standard height of a kitchen chair is 40-45 cm from the floor to the seat (height to the back from the floor is 90 cm). The optimal height is 40-42 cm from the floor to the seat.

Kitchen stools are usually 42-48 cm. If the kitchen stool is higher, there should be a leg support (there should be a distance of 32-42 cm from the support to the seat).

The optimal seat depth is 40-45 cm (the seat should not dig into the knees). It will be comfortable for a person of average height to sit at a table with a height of 74 cm.

In addition, the distance from one person to another should be taken into account, it is comfortable when one person has a width at the table of at least 50 cm. And the distance between the legs is rectangular tables must be at least 91 cm.

But in order not to doubt and not to think, just use the formula for calculating the height.

The formula for calculating the height of the kitchen table

For example, with a height of 175 cm, you will get the result: Height * 75 (standard height) : 165 ( average height- it is better to calculate it for family members separately, if everyone in the family is tall, then it is easier to immediately take the arithmetic average of the height of all family members) = 79.5 cm ( optimal height for a man of that size). 175*75:165=79.5

To find out the height of the kitchen chair that is comfortable for your height, subtract 40-45 cm from the resulting figure (depending on height - if you are tall, then 45 cm, if you are low, then 40 cm, medium - 42 cm). 79.5-42 = 37.5 should be the distance from the seat to the table. That is, the height should be within 40-45 cm.

On average, the distance from the tabletop to the seat should be 30 cm for a comfortable seat.

The standard height of the kitchen table is 0.8 m, work surfaces 0.9 m. However, this height is calculated for a person with a height of 1.65 m, if you have a different height, then you can calculate desired parameters themselves using the formula given in the article.

Among the list of criteria affecting rational choice kitchen table, its height becomes one of the dominant indicators. A comfortable fit depends on it, if it is, as well as comfortable activity, if we are talking about working kitchen tables.

Standards for kitchen tables

Regulatory documents regulate the dimensions furniture items. The main one is GOST 13025.3-85. In accordance with its provisions, the distance from the floor to the lower plane of the tabletop is set to a minimum of 0.61 m, respectively, to its top, the size of the distances varies from 0.72 to 0.78 meters.

The unit of reference is usually taken as the average height of a person - 1.65 meters. This is what causes the inconvenience that sometimes arises when the table turns out to be low or, on the contrary, extremely high, since everyone's height is different.

Discomfort is expressed in the inconvenience of using cutlery competently and fully if the countertop is too high. If the table is low and it is impossible to take comfortable posture, since you have to bend over, slouch, then by the end of the meal there will be a feeling of fatigue and aches in the spine.

Table Height Formula

There is a simple technique for interpreting the average standard height of the countertop (Hst ≈ 0.75m), taking into account the average growth rate (Рav = 1.65 m), for one's own height (P). Ideal Height selected dining table (H) is calculated by the formula:

H \u003d Hst ∙ P / Rav.

For example, having a height of P = 1.8 m, the most comfortable arrangement will be observed at a table with the following estimated height:

H \u003d 0.75 ∙ 1.8 / 1.65 ≈ 0.82 m.

Of course, such a calculation is rationally suitable for one person, but more often several households gather at a meal. In such a situation, it is advisable to take the arithmetic mean of the growth of adult family members as a basis, and for the younger generation, you can purchase special chairs that make it easy to adjust their height.

Optimum desktop height

It is important to know and take into account the optimal height of desktops, where the hostess spends a lot of time. Ideally, compliance should be observed, and standard kitchen in each functional area, which has a specific purpose, is focused on the normative range of heights (m):

washing dishes - 0.85 ÷ 0.95;
cutting raw species products - 0.82 ÷ 0.85;
cooking - 0.8 ÷ 0.85;
kneading, rolling dough - 0.7 ÷ 0.82;
workspace for installation kitchen appliances, saucepan with prepared food and other needs - 0.85 ÷ 0.87.

If we take for example a cutting surface, which, with average growth rates (1.65 m), should rise above the floor by a maximum of 0.82 m, then for more tall man this indicator should be increased. You can make an approximate list of the optimal height of the desktop.

A height of 1.7 m will require a cutting plane height of 0.85 m.
At 1.75 m, a worktop level with a mark of 0.87 m is appropriate.
If the growth reaches 1.8 m, then it is more convenient to work on a surface that is 0.9 m from the floor level.

Knowing these patterns is of great help if you plan to independent production kitchen furniture.

In furniture collections, the standard height of kitchen tables is usually 0.85 m. This does not always suit women, and especially men, who are quite impressive in height. Manufacturers have taken into account the relevance of such a problem and now you can purchase a kitchen table model that allows you to adjust the vertical level of its installation.

Chair height

In order for the optimal height of the tabletop, selected in exact accordance with the growth, to be really comfortable, it is necessary to correctly select the chairs. Based on the calculated values \u200b\u200busing the above formula, it should be subtracted from the result obtained 0.45 m for high (> 1.7 m) growth, respectively 0.42 m, if the growth is average (≈ 1.65 m) and 0.4 for low person (< 1,6 м).

Therefore, having a height reading of 1.8 m, having picked up a table, according to the previously calculated results with a height of 0.82 m, it is advisable to put a chair for yourself with a height of 0.82 - 0.45 \u003d 0.37 m. These calculations are especially convenient if it is accepted solutions all chairs to buy from the range with adjustable legs. In such a situation, not only household members are satisfied in a comfortable seat at the table, but it is also possible to create an excellent environment for guests, regardless of height.

When choosing furniture, you should pay attention to such an important quality as the conformity of the parameters of the product with the parameters of the human body. All the same modern life forces us to a sedentary lifestyle, which means that you need to try hard to find the chair that will be comfortable for you in every way.

The main anthropometric indicators of the average person

The figure below shows some anthropometric data of a human figure at rest, in motion and during the operation of furniture. Given the above data, most furniture sizes have a standard.

Based on them, all the main patterns have been developed. Let's move on to particulars.

Chair options

For example, if the height of the table is 720-750 mm, then the seat height of the chair should be 430-450 mm. Height reduction possible working surface table up to 680 mm (to work with a keyboard, typewriter).

For seats, the width at the widest part of the chairs must be at least 360 mm, if the chair is working, then all 400 mm. When using backs with curvature in furniture, the radius of curvature should be 450 mm for regular full-size backs (their height is up to 320 mm), and 220 mm for lumbar backs (height exceeds 320 mm).

Types of chairs and their sizes

Chairs are absolutely different forms, therefore, depending on the purpose, they can decorate the kitchen, nursery, office and living room. Let's figure it out in order.

Increasingly, bar counters are decorating not only studio apartments, but also kitchens in one-room apartments, the dimensions of which leave much to be desired. If your kitchen has a bar counter, then to complete the picture, you should purchase bar stools. They will be in harmony with each other, which will create a single, complete style.

Standard bar counter sizes - 120x55x105(length-width-height, cm). Of course, these parameters may be different:

- The height of the factory racks, as a rule, is 110/120/125/130 cm;
- If the stand is part of a headset, then its height is 860/880/910 cm.

These parameters are obtained as a result of a simple calculation, taking into account: the plinth of typical furniture is 100/120/150 mm in height, the thickness of the countertop is within 40 mm and the height of the facade is 720 mm.

It is on the basis of them that you need to choose bar stools

Bar stool sizes

The dimensions of bar stools directly depend on the height of the bar counter. So:

- if the bar counter is 110 cm high - options for bar stools 75 cm high should be considered;
- if the rack is 120 or 130 cm - pay attention to the models of chairs with a height of 85 cm.

The table shows the recommended sizes of bar stools depending on the height of the bar. Keep in mind that it is not necessary to strictly adhere to these particular figures, the main thing is that the difference between the height of the table and chairs should not be less than 30:

Little trick:

To save space in the kitchen, you should not buy traditional bar stools, but high plastic stools. They can easily fit under the counter if needed. And for a small kitchen, transparent plastic chairs that have recently come into fashion are suitable.

Bar stool - stylish detail interior, which is very popular in the West, but has recently become increasingly popular in our homeland.

Baby chairs and their sizes

Children's chairs are often sold as a set with a children's table. square shape. So, if the length and width of the table is 59.5 cm, and the height is 53.5 cm, then the parameters of the chair should be as follows:

- height - 57 cm;
- length - 30 cm;
- width - 28 cm.

Above are standard sizes, from which you can build on as a model. If you need to slightly modify the parameters, then you can always contact the carpenter, and he will complete the order according to your individual measurements and preferences.

office chair

There are two types of office chairs: on wheels and on stable metal legs. Yes, measurements standard office chair on wheels will be as follows:

- height - ranges from 112 - 124 cm, where the lower part is 41 - 54 cm, and the upper seat is from 63 to 68 cm;
- length - 43.5 - 45 cm;
- the diameter of the semicircle of the wheels is 60 cm.

Classic armchair with stable legs usually these parameters:

- height - 80.5 cm, where the lower part is 50 cm, and the upper seat is 30.5 cm;
- seat length - 40.5 cm;
- the width of the legs on the bottom - 60.5 cm.

How to choose an office chair?

Jens Kapelman, head of sales for Dauphin, one of the largest German manufacturers armchairs, gives advice on how to choose a good office chair for minimal money. Ask the seller the following questions:

Does the chair have a synchro mechanism?
This is when the seat and back synchronously and automatically repeat the movements of the person sitting: forward, backward, sideways. Thus, without losing the contact of the spine with the back of the chair, the person is in active movement, the spine is relaxed, there is no unnecessary tension on the muscles. This is the main thing. Without a synchro-mechanism, a chair is not a chair, but a stool with a back.
Is there a backrest adjustment?
Each person has a different weight, so the different forces that we put on the back of the chair must be proportionally compensated by its resistance. Otherwise, fragile little girls will sit like soldiers, unable to overcome their backs. And large men are always in a relaxed reclining position, which is not very well received by the authorities. It's good when you find a balance: the back should deviate relatively easily - but not so much as to "fly away". Adjustment can be mechanical or automatic.
Is there a seat depth adjustment?
According to the rules of ergonomics, there should be a distance from the edge of the seat to the inner bend of the knee with the width of your palm. If it is less - you "slide" from the chair. If it is more, you drown in it, forcing the leg muscles to strain unnecessarily.

Whether there is a negative angle seat tilt?
And, at the same time, backrests, less than 90 degrees - this is when the backrest, following the seated one, sort of descends to the table. The negative tilt of the seat is needed in order to get rid of excess pressure on inner part thigh, due to which the blood flow is clamped in this place and the muscles do not receive proper nutrition and oxygen. This happens when you are forced to work for a long time in a position tilted to the table (writing with a pen, peering at the data on the monitor). Claim a negative slope!
Are there armrests?
When you want to save money, the first thing you get rid of in a chair is the armrests. And this is a mistake. The armrests are aligned with the tabletop, so the wrist, forearm and hand on the keyboard (or with a pen) are always at the same level. The arm (including the shoulders) is always relaxed. And that's great. There are no armrests - and all day long your muscles do nothing but support your arms, forcing your shoulders to rise higher and higher, leading to slouching and increased tension in the shoulder girdle. In the armrests, the ability to adjust their height and width is important. All sorts of 3D and other mechanisms - from the evil one.
Is the back height adjustable?
More precisely, the height of the lumbar support. Well, if yes. The lumbar support provides the closest contact between the back of the chair and the point of greatest curvature of the spine. It is bad when the lumbar support rests on the buttocks or, on the contrary, almost on the shoulder blades. The tighter the contact, the more relaxed the sitting posture. But, in fact, the height of the backrest does not play an ergonomic role. This is purely a symbol of the status and importance of the seated person, nothing more.

All. The "minimum" program has been completed. The remaining options are a matter of subjective wishes and available budgets.

And finally, a few comments:

- The mesh back is not inferior in ergonomics to a regular back upholstered in fabric. Mesh is more convenient in summer time- well passes air, is ventilated.

- The headrest is a completely empty fixture. It has no ergonomic role.

- The plastic base of the chair is not inferior in its characteristics to the metal one. Modern plastic in chairs is special, high-strength. Serves quietly for 10 years or more, is not particularly susceptible to any serious damage.

When choosing a work chair, it would be good to pay attention to the fabric with which it is upholstered. Main characteristic fabrics - an index of its abrasion, wear resistance. It is expressed in martindales. For office chair this index must be at least 80 000 .

- It is worth clarifying the type of wheels. They are for hard floors (with soft felt nozzles so as not to damage the floor) and, on the contrary, for soft floors (with plastic nozzles to glide better on the carpet).

— The normal warranty for the office chair is 5 years. If they give less - a reason to think.

- If you need to save money: choose cheaper fabric, plastic chair base, mechanical, and not automatic adjustments, lower back. You can’t save on mechanisms and armrests.

Dining (kitchen) chair

Ideally, dining or kitchen chairs should be practical, durable, lightweight, made from hygienic, easy-to-clean, moisture-resistant materials and, of course, in harmony with the color and design of the table.

To choose a kitchen table correct sizes, again, should be based on the size of the dining table. So, if you have a kitchen table with a height of 75-80 cm, respectively, chairs should be considered from a height of 96 cm, where the height of the seat will be 45 - 48 cm. Width and depth of 42 and 48 cm, respectively.

A few tips:

- If the chairs are made of solid wood, then they must be subjected to additional processing moisture protective compounds.

- AT modern kitchens furniture such as plastic or acrylic chairs, complemented by a chrome metal frame, will also look good.

— Plastic chairs with chrome legs in the interior of the kitchen

- Transparent, as if "invisible" chairs are perfect for a small kitchen.

- Chairs can have hard seats, soft or semi-soft seats. In the latter cases, the upholstery is often made of microfiber, a high-quality and practical material with water and dirt-repellent properties. This furniture is often complemented by upholstery made of durable Teflon impregnated material, leatherette or leather.

— Do not want to choose chairs in the color of the table and furniture? Choose chairs to match the curtains or some color accent (wall, backsplash, decor, etc.).

height - 47 cm;
length - 32 cm;
width of the legs at the bottom - 32 cm.

When determining the overall and functional dimensions household furniture it is necessary to be guided by the standards “Household furniture. Functional dimensions "(GOST 13025.1 - GOST 13025.18). They are installed in accordance with anthropometric characteristics and taking into account the size, quantity and rational placement of household items. Dimensions of products and individual elements that are not stipulated by the standards are established by projects for this product. Below are the functional dimensions of the main furniture products.

Dimensions desks and secretaries are shown in Fig.8.

Fig.8

The distance between the front edge of the table top and the depth limiting element must be at least 400 mm. The distance from the floor to the working plane of products for typing, working on a computer and other organizational equipment is at least 680 mm.

Accepted minimum dimensions working plane of desks: length - 800 mm, width - 500 mm, and secretaries - respectively 700 and 400 mm.

The internal dimensions of boxes and half-boxes for papers must be at least 340x240 mm, and their depth - 65 mm.

When designing tables complete with chairs, work chairs or stools, the height distance between the working plane of the table and the seat of the chair, armchair or stool should be 290-310 mm, and between the lower edge of the under-table and the seat - at least 190 mm. In transformable tables with a cover doubled in thickness, the distance between the working plane and the seat can be increased by the thickness of the table cover.

The main functional dimensions of products for installing TVs are as follows: the height of the plane for installing a TV is 500 mm, the width is 390-600 mm.

Children's furniture is made in several rooms, taking into account the average height of children. Thus, tables and chairs are produced in five numbers: 00; 0; one; 2; 3 respectively for the average height of children 750; 900; 1050; 1200; 1350 mm.

Children's beds are made in two types: I - with a fence and a variable bed height, for children under the age of 3 years; II - for children aged 3 to 7 years. Their dimensions are as follows (mm):

In type I beds, it must be possible to move down the side rail during operation by at least 135 mm. By agreement with the consumer, it is allowed to manufacture children's beds with large lengths and widths.
