Seat size (WxD)
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
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.
Back material
The main material used for the back of the chair. Note that some models are available in several design options that differ in materials; for such models, all available options are given.
-
Fabric. Relatively inexpensive and at the same time quite practical material. It has good strength, unpretentious care, while it can be performed in a variety of colours and designs; in addition, it provides good ventilation, which can be useful in the heat.
— Skin.
Genuine leather is expensive and well emphasizes the status of the owner (especially since the leather products themselves look solid and rich). Accordingly, the main area of use of this option is executive chairs (see "Appointment"). On the practical side, the skin is durable, quite pleasant to the touch, but it does not breathe well (which can create discomfort in hot weather) and requires some care, otherwise it may lose its “presentation”.
- Leatherette. There are many varieties of leatherette, which differ markedly in price and properties, and the most advanced of them are used even in premium executive chairs.
Leatherette backs are not as demanding to care as genuine leather, but are less durable and more susceptible to wear and abrasion.
-
Grid. The backs are in the form of a rigid frame, in which a fabric or synthetic mesh is stretched. Th
...e 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, one can single out perhaps a slightly lower reliability and greater complexity of repair than in a fabric similar in many respects (see above).
— Plastic. Pure plastic backs are most often used in chairs with seats made of the same material (see above). They are durable and inexpensive, but due to their rigidity they are rather inconvenient, as a result of which they have not gained distribution even among models for visitors.
- Wood. Wooden backs are in many ways similar to the plastic ones described above, except that they cost a little more and can have an original appearance due to the texture patterns of the tree. They are also rarely used because of the rigidity and the inconvenience associated with it.
