Max. user weight
The highest weight that the chair is guaranteed to withstand with regular use — in other words,
the maximum weight of a seated person, allowing you to constantly use the product in normal mode without fear of unexpected breakdown. Note that many models are able to endure short-term excess weight without problems, however, anyway, it is not worth overloading the structure (and even more so doing it all the time): off-design loads will significantly increase its wear, and breakdown can occur at the most unexpected moment.
Headrest
The presence of a
headrest in the design of the chair.
The role of the headrest can be played as a stand, made separately from the backrest, and the upper part of the backrest — if it has a pronounced characteristic shape or a pillow is supplied in the kit, which can be installed at the request of the user. The simplest high backs that do not have a characteristic upper part are not considered head restraints.
Anyway, this feature provides additional comfort — especially when reclining back. On the other hand, if you have to sit mostly straight in the chair and the back plays a symbolic role, perhaps the best choice would be a model
without a headrest(especially since such chairs are cheaper).
Footrest
The presence of an additional
footrest in the design of the chair. Such a stand is usually made folding and located under the seat, and when unfolded it rises forward to a horizontal or almost horizontal position; On some models, the tilt of the stand can be adjusted. Anyway, this feature allows you to unload the legs, which not only provides additional comfort, but also has a positive effect on the ligaments and joints.
Removable cushions
Removable pillows can be both under the head (with their help, the back bend in the neck area is additionally regulated), and under the back (act as an auxiliary lumbar support). Basically, they come in pairs, but it happens that either a pillow for the head or only for the back is supplied with the chair. As a rule, removable pillows are fixed on the belts.
Adjustment
Armrest settings can be quite extensive. In everyday life, there is even a marking 1D, 2D, 3D, 4D, depending on the number of adjustments. The following adjustment options are available:
height,
length(forward / backward),
width(right / left),
tilt and
swivel(right / left). More about them:
- Height. The ability to adjust the height of the armrests relative to the level of the seat. This feature allows you to adjust the arm rests for maximum comfort and minimize shoulder and neck fatigue.
- Turn (right / left). In this case, the possibility of turning the armrests to the right or left is implied, so that they are not parallel, but “look” in different directions.
— By length (forward / backward). Length adjustment refers to the ability to move the armrests back and forth for the convenience of placing hands under a certain physique of the user of a computer chair.
- By width (right / left). Adjusting the position of the armrests to the right or left in a horizontal plane. The stem adjustment contributes to a comfortable fit and allows you to adjust the chair to a certain arm span.
- By tilt. This adjustment assumes the presence of armrests mounted on swivel mounts. It can work as a height adjustment: turning the armrest in the mount changes not only i
...ts inclination, but also the height of the point of contact with the arm. However, the matter is not limited to this: in many models, the handles can be placed vertically (raised or lowered) and, in fact, the armrests can be removed in this way.
If it is assumed that the position of the armrests can only be adjusted in height, they are marked with the designation 1D. For 2D armrests, in addition to the height adjustment, the ability to rotate the palm rests to the right / left (around the axis) is added. 3D armrests are adjustable in height, rotate around the axis and move back and forth. Finally, 4D armrests are considered the most functional - they additionally have the ability to shift the surface of the armrest to the side.
