How tall should a chair be?

The convenience and comfort of a seated person directly depends on the size of the chair, so you need to pay due attention to the choice of this piece of furniture. The main criteria will be the characteristics of the customer’s body, the purpose of the chair, the room or room for which the item is purchased. Depending on this, you can divide the chairs into several groups.

Chairs for the kitchen can be of various shapes and colors. They are made of wood, metal, plastic and even glass.

The height of the kitchen chairs should be related to the height of the table.This is an important indicator of comfort, and although many sellers can assure you that they are all the same, but in fact this is far from the case.

In accordance with the standard indicators GOST (for a table 72-78 cm) sizes may vary:

• The required height of the object from the base of the floor to the top of the back is 800-900 mm;
• Size from floor to seat is in the range of 400-450 mm;
• The height of the part you lean on should be at least 450 mm;
• The width of the backrest and the seat - from 350 mm, and the depth - 500-550 mm.

For bar counters the height of the chair will be different. Here you also need to consider the level of the surface over which you will sit.

Depending on this, the size from tile to seat will vary between 750 and 850 mm. The width of the seating surface should start from 460 mm, and the depth from 320 mm. Tilt radius will be 450 mm for typical models and 220 mm for lumbar ones.

In bar models not an extra accessory will be the footrest for the feet for support. If you have a kitchen worktop height of 90 cm, the bar model for seating will be 65 cm.

Nowadays, both tables and chairs can be made to order. The master will take into account all the individual characteristics of the customer's body: measure the height, weight, lower leg and hip part of the body.

Tables and chairs of this type are more comfortable than ordinary kitchen. Typically, restaurants use semi-chairs or chairs with armrests. This creates more convenience and comfort, but at the same time takes up less space than when placed in armchairs.

It also allows you to save space in the room and seat more people. However, it must be remembered that the width of one seat must be at least 500 mm in order for a person to feel comfortable at the table.

Restaurant models can have an inclined back that allows you to take a more relaxed posture and facilitates communication. Also, these chairs are wider, deeper, higher than the standard options. In this case, do not forget about the convenience of the waiters. For this, the height of the object should not exceed 1000 mm.

Choosing a working chair, you need to know that the desired height of the chair for food and work are different. Most modern models have the ability to adjust the height and depth of the seat, the position of the back, but there are models on four legs with a strongly folded back.This position is not convenient for most people.

Constantly being at your desk, “lounging”, is not comfortable, and if you straighten up and sit without support, then by the end of the working day your back will hurt a lot.

SanPiN recommends the following standard when choosing the right chairs for subordinates:

• The width and depth of the seat should start at 400 mm;
• The seat should have a height adjustment in the region of 400-450 mm, the slope is measured in degrees: forward 15, and backwards 5;
• The front of the seat should be rounded;
• It is necessary that the back had values ​​from 300 to 380 mm, its angle of inclination was close to the figure of 30 degrees;
• The length of the armrests is recommended to choose at least 250-260 mm, width about 60 mm;
• Armrests should also be adjusted in height and width.

Choosing the right chair for a child is especially important, since from childhood you need to take care of the formation of a correct posture.Also, from too small a piece of furniture in a child, blood circulation may deteriorate, and from a large one, vision.

As with adults, the size of the highchair depends on the table and the height of the child.

• With growth up to 80 cm, the child will have a height of 17 cm;
• 80-90 cm - 20 cm;
• 90-100 cm - 24 cm;
• 100-115 cm - 28 cm;
• 110-120 cm - 30-32 cm;
• 120-130 cm - 32-35 cm;
• 130-140 cm - 36-38 cm.

Choosing a child seat, follow the following rules.

• Try to seat the child on the chair. Place both feet flat on the floor, with the angle that forms the shin and thigh, must be 90 degrees. If you have an obtuse angle, then you need to choose a smaller model, and if sharp, then a larger one.
• It is required that the height from the knees to the table top be 10-15 cm.
• The depth of the seat should be sufficient so that the seat does not crush under the knees of a person.
• It is necessary that the back of the chair forms an angle of 90 degrees, was securely fastened, so that the child could lean on it without a large backward tilt.

If you purchased a chair, the size of which is necessary to increase, you can make a wooden stand under it, which should be securely fixed. If you want to lower the model, then you need to cut the base with the jigsaw, if this allows the selected product.

Currently, there are so-called "growing" chairs that allow you to adjust the height of the seat relative to the floor level. Such models are cost-effective, as they allow you to use them for a long time.

If you decide to buy factory furniture, before going to the store it is better to calculate these dimensions "by yourself". First of all, decide what size the table will be. If you buy a new table, then you need to decide on his choice, and then take up the rest of the furniture. There is some standard formula for the calculation, which will be discussed below.

To begin, measure your height and the growth of the rest of your family. It is necessary to calculate the average height of your household. It is taken as the arithmetic mean of growth. For example, your height is 178 cm, the average height of the family is 167 cm. Next, take the ratio: 178 * 75 (standard height) / 167 = 79.9 cm. This will be the ideal height of the kitchen table.

Now subtract from the resulting figure from 40 to 45 cm (depending on height: the higher the person, the closer to 45 cm).In the example above, 79.9-43 = 36.9 cm is obtained. This is the optimal distance from the table to the seat. The length of the back is chosen at its discretion, but remember that the standard size is 90 cm.

This formula is valid when choosing bar items, and office, but for children’s models it is better to start from standard sizes or to buy by “fitting”.
