Comparison Aerocool Count vs Burokrat CH-778

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.

Chair back height; for models with a variable back height (see "Adjustments"), as a rule, the maximum value is indicated.

The back height is measured from the seat to the top edge. In essence, this is the height of support available to the back. In some situations, you can not pay much attention to this indicator - for example, if the chair is intended for visitors and the role of the back in it is purely symbolic. However, if you have to sit in a chair often and for a long time, this point should also be taken into account. Ideally, it's best to try a few chairs "live" and find out which backrest height is most comfortable for you. If this is not possible, it is worth deciding which area on the body the back should reach (to the shoulder blades, to the base of the neck, etc.) and measure at what height from the seat this area is in a sitting position. And if you need specific support for the back of the head, you should choose among models equipped with head restraints (see above).

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.

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 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 chair seat is made directly. Note that individual models can be produced in several versions, differing in the material of the seat.

— Textile. The fabric can have many varieties, and specific characteristics depend on the price category of the chair. And this material is found in all categories — from low-cost models to rather expensive products. The common properties of all types of fabric are low cost, durability, as well as undemanding maintenance.

— Skin. The main distinguishing features of genuine leather are the rich appearance and the corresponding cost. Thus, this material is considered "image" and is used not only for comfort, but also to emphasize the status of the owner. Accordingly, most chairs with leather seats are designed for executives (see "Appointment") and are in the premium class. On the practical side, the leather is durable, quite pleasant to the touch, but poorly breathable (which can create discomfort in hot weather).

— Leatherette. A variety of artificial materials that mimics the natural leather described above. The quality and properties of a particular leatherette, usually, directly depend on its cost (and the price category of the chair in general), but even the most expensive options are usually cheaper than leather — despite the fact that outwardly and even in sensations they can be almost indistinguishable from i...t. In addition, this material is not so demanding to care for. Thanks to this , leatherette seats are quite common. Their main disadvantages are the tendency to scuffs and, in general, a shorter service life than leather ones (but again, a lot depends on the price).

— Plastic. Plastic seats are typical of the most inexpensive chairs designed for visitors — or for staff who do not have to sit in one place for a long time. This material is characterized by low cost combined with strength, reliability and an abundance of colours. At the same time, it has one key drawback, which actually nullifies all the described advantages — hardness; Simply put, sitting on plastic is uncomfortable. Because of this, even among the models mentioned, all-plastic seats are very rare.

— Wood. The word "wood" in the case of seating for office chairs usually refers to plywood. This material is in many ways similar to the plastic described above, but it also has some differences: on the one hand, it has an aesthetic appearance with original patterns and is considered more pleasant to the touch, on the other hand, it costs more and provides relatively few design options. However, such a disadvantage as hardness is also characteristic of this material, which is why it is also used only in isolated cases.

— Net. Seats in the form of a rigid frame, in which a fabric or synthetic mesh is stretched. The main advantages of such designs are light weight and good breathability. The design of the nets allows them to be used even in executive chairs. Of the noticeable shortcomings of mesh seats, one can only single out a slightly lower reliability and greater complexity of repair than those of largely similar fabric seats (see above).
