Comparison GT Racer X-2534-F vs GT Racer X-2527

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 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.

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 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.

The material from which the base of the chair is made (see "Base construction").

— Plastic. Plastic is notable for its low cost, combined with ease of processing — it can be easily given even a rather complex shape. This material is considered less durable than metal, but modern plastics are able to provide sufficient strength even for chairs designed for high loads (see "Maximum user weight"). However this is true only for bases of the "cross" type; for the legs and skids, the plastic is still not strong enough. However, it is found in models of all price categories.

— Metal. The main advantage of the metal is its high strength, due to which it can be used for all types of bases. At the same time, it is somewhat more expensive than plastic, and therefore, among armchairs with a cross, it is found mainly in models of the middle and higher levels.

— Tree. Wood can be attributed to design materials: it is used not so much for practical reasons as to provide the chair with a stylish and aesthetic appearance. At the same time, it is considered more reliable than plastic (although not as reliable as metal), so it can even be used for skids. However chairs with wooden bases are quite expensive.
