Shoulder back width
The width of the back at the shoulders of the intended wearer.
In order to recline as much as possible on the back, this width should be no less than the actual width of the user's shoulders. At the same time, for more or less comfortable use, a smaller back size is also sufficient — approximately corresponding to the width of the back in the area of \u200b\u200bthe shoulders (between the outer edges of the shoulder blades). Well, anyway, this parameter is, on the one hand, secondary, and on the other, very subjective. This means that in most cases you can not pay much attention to it, however, if you have already decided to choose the furniture that is the most suitable in size, it is better not to measure your own back, but to test several chairs and determine the most convenient value by experience.
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.
