Back height
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).
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.
Headrest height
The ability to change the height of the headrest. For more on the role of the function itself, see "Headrest"; here we note that this adjustment makes it easier to adjust the chair to the height of the user, however, it is possible to
adjust the height of the headrest only if the headrest is a separate part, and not an extension of the backrest.
Headrest tilt
Changing the inclination of the headrest changes, accordingly, the inclination of the head resting on it. This allows the user to choose the optimal position for their preferences and specifics of the situation.
Backrest tilt
The ability
to change the backrest tilt back and forth. Allows users to adjust the chair depending on how they prefer to sit: straight or slightly leaning back.
Seat material
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).
