  3. The ability to adjust the height of the seat is an important criterion when choosing an office chair. The same applies to adjusting the backrest. Adjust them so that the position of your body is perfectly correct and work without pain and fatigue.
  4. Choose a chair on which the front of the seat is slightly bent down. This will provide comfort when sitting, ensuring a comfortable position on the back of the thigh and the inside of the knees.
  5. Give preference to chairs whose upholstery is made of soft, breathable and non-slip fabric. Thus, you will provide yourself with a comfortable seat, both in the summer and in the winter season.

How to adjust the chair

Proper adjustment of the computer office chair is a rather important point in the organization of the workplace. After all, you should ensure not only a comfortable position of the user, but also to prevent such unpleasant moments as pain and back fatigue as much as possible.

All modern models of office chairs, both pneumatic and non-pneumatic, quite easily change the position of different parts of their structure with the help of special adjusting bolts and levers.

Setting up a chair for individual parameters of a person consists of several stages.

Adjusting the seat height of the computer chair in accordance with the height of the workplace and your own height

Criteria to determine the optimal height of the office chair:

  • the ideal position of the seat height can be determined in a standing position - the highest point of the seat should be below the knee,
  • in a sitting position, you should sit at a comfortable distance from the table, put your hands on it and straighten your back so that the shoulders are parallel to the spine, and the angle of the bent arm should be ninety degrees. If your palms are below the elbows, this means that the seat of the chair is low for you,
  • Determine the correct position of the legs relative to the seat. To do this, place your feet parallel to the floor - the distance between the front of the seat and the thigh near the knee should be about 1.5-2 cm. If the distance is greater, then you need to raise the chair. If the finger hardly passes or does not fit at all between the seat and the hip, this means that you should raise your legs. To do this, adjust the seat, and in the absence of such an opportunity - use a special stand.

You can adjust the height of the chair in the following way - slightly stand and raise the lever located under the seat. When reaching the desired height, release it.

Adjusting the height of the seat down is carried out without getting up from the chair - just pull the lever. When the chair under the weight of your body drops to the desired height, release the lever.

Seat depth

This parameter is quite important, as it allows a person not to stoop while sitting in a chair, and also helps to minimize the load on the back, which, in turn, prevents various injuries.

To determine the correct depth of the chair, you need to sit down, the back is flat, feet on the floor. Then measure the distance from the front edge of the seat to the back of the lower leg. The ideal width of the space is about five centimeters. If the distance is shorter, this means that the chair is too deep and the back should be moved forward. If the width is more than 5 cm, then it needs to be moved back.

How to adjust the depth of the seat? In most cases, this can be done using a special lever. If this is not possible, use special supports for the back or orthopedic pillows.

Backrest adjustment

It is no less important than the depth of the seat. The angle should be such that it can support the back when you are sitting in your favorite position.

There is an adjustment screw on the back of the backrest to help you adjust the angle to the value you need. To do this, unscrew the screw and, leaning forward or backward, determine the most convenient position for yourself. When the choice is made, lock the screw.

Armrest adjustment

Put your hands on the surface of the table or keyboard so that the angle in the elbow joint is ninety degrees. In this position, your elbows should lightly touch the top of the armrests, moving freely from one side to the other. When they completely lie on the armrests, this restricts movement and quickly leads to fatigue, as the hands significantly feel the additional load.
