The choice of a computer chair must be taken very seriously. Because this is where you have to spend a lot of time. A poorly selected chair can not only have a negative impact on your health, but also affect your work efficiency. The choice of a computer chair depends not only on how much time you spend at the computer, but also on physical characteristics, such as height and weight.
If you spend no more than 1-2 hours at the computer, for example, at home checking email, reading news, etc., then a standard chair with a minimum number of adjustment functions will be enough for you. The price of such a chair is affordable.
Spending 3 to 5 hours at the computer, you probably use the chair more for work than for entertainment. With such a significant load on the body, you should choose a chair with the ability to adjust the tilt of the back, the height of the armrests, and the seat. It is advisable to choose a chair with hygroscopic (moisture permeable) upholstery.
If a personal computer is a part of your life, and you spend at least 5 hours a day on it, then in this case you should not skimp when choosing a chair, otherwise it can harm your health. You should choose a computer chair that changes the position of the backrest depending on the position in which you sit. It is advisable that the chair be equipped with a mechanism with a locking function in an inclined position. For example, a chair (MK A100 mesh) was suitable for me, since I work at home and sit at the computer quite a lot, this chair is comfortable because it is adjustable as you like and has heavy-duty mesh fabric, so my back does not sweat.
When you need maximum comfort when working at a computer for a long time, you should choose an ergonomic chair. There are models that have many manual adjustments. The orthopedic back of this chair tilts at different angles and is equipped with a headrest (adjustable in many models). The upholstery is made of a special, “breathable” material. As a rule, such chairs have a metal frame and legs.
Requirements for a computer chair.
Armrests and casters.
Armrests are required. They will help relieve some of the load from the spine. If the armrests are adjustable, this will reduce fatigue in the cervical vertebrae and shoulders. They are made mainly from polyurethane foam, plastic, and metal. In most models, the armrests are equipped with soft pads.
You also need to take a close look at the wheels. To protect the floor covering (parquet, laminate), you need rubberized, easily rotating wheels (WRS rollers). But, it should be taken into account that if you have a carpeted floor, it is better to choose ordinary plastic wheels, which will glide on it better than rubberized ones.
Base (cross).
The crosspiece can be metal or polyamide plastic. Both options are reliable and allow a load of up to 140 kg.
Gas lift or pneumatic mechanism.
To adjust the seat height, a pneumatic mechanism is used, or as it is also called a gas lift. When assembled correctly, this reliable mechanism can easily lower and raise a person weighing up to 150 kilograms.
Swing adjustment.
Chairs almost always use a rocking mechanism. As a rule, chairs in the middle and high price ranges are equipped with such a mechanism. Main modifications of swing mechanisms: "Top Gun" - swing with fixation in the working (vertical) position
"Multiblock" - rolling with fixation in 4 positions
"DMSL" - rolling with fixation in any position. Backrest tilt.
Not a single computer chair can do without this mechanism, except perhaps for the simplest models. The tilt of the back allows you to reduce the load on the spine and back muscles.
Back and seat.
There are two types of backrest - ergonomic and classic. The ergonomic one has lumbar back support, a headrest to relieve tension in the neck muscles, and thickening along the edge of the seat for a more comfortable position in the chair. It is recommended to choose a chair with a high back for home use. Mid-height chairs are more suitable for the office.
