Comparison Dxracer Classic OH/CT120 vs Dxracer Iron OH/IS133 FT

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.

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.

Dimensions of the seat installed in the chair in width and depth (from the back to the front edge). For models with variable depth (see "Adjustments"), the maximum value is taken into account when the seat is pushed forward to the stop.

Most modern chairs are designed for the average adult, so paying attention to size is primarily for people of a large, or, conversely, miniature physique. In width, the average is considered to be 45 – 55 cm, the narrowest models are up to 40 cm wide, in the widest it can exceed 60 cm. Similarly, a depth of less than 40 cm is considered small, up to 60 cm — medium, more than 60 cm — large.

Seat height from the floor. The optimal height for a person of average height is considered to be 40 – 50 cm, however, this moment is largely subjective, and the comfort of the chair for a particular user depends heavily on his preferences and physique. Thus, many models have the ability to change the height in a certain range (see "Adjustments"). To choose, it is best to determine “live” at what height you are comfortable sitting, and find a model with the appropriate characteristics.

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).

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.

The height of the armrests installed in the chair relative to the seat. In models that have the ability to adjust the armrests in height (see "Adjustments"), the range of such adjustment is usually indicated.

The overall comfort of using the chair depends on the height of the armrests, but this parameter is largely subjective: even people of the same height can differ in physique and personal preferences. So if comfort is of fundamental importance to you, it is best to check live what armrest height is optimal and choose a chair with the appropriate specifications.

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 cha...nges not only its 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.
