Max. user weight
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.
Back height
Высота спинки кресла; для моделей с изменяемой высотой спинки, как правило, указывается максимальное значение.
Высота спинки измеряется от сидения до верхнего края. По сути, это высота опоры, доступной для спины. В некоторых ситуациях на этот показатель можно не обращать особого внимания — например, если кресло предназначается для посетителей и роль спинки в нем чисто символическая. Однако если сидеть в кресле предстоит часто и подолгу — стоит учесть и этот момент. В идеале лучше всего попробовать «вживую» несколько кресел и выяснить, какая высота спинки для вас является наиболее комфортной. Если же такой возможности нет — стоит решить, до какой области на теле должна доставать спинка (до лопаток, до основания шеи и т. п.) и замерить, на какой высоте от сидения находится эта область в сидячем положении. А если вам нужна конкретно опора для затылка — стоит выбирать среди моделей, оснащенных подголовниками.
Спинка считается
высокой, если она имеет высоту не менее 65 см. Благодаря таким размерам кресло обеспечивает опору практически на всю спину сидящего человека, а нередко — еще и на затылок. В то же время стоит учитывать, что далеко не всякая высокая спинка является подголовником.
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.
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.
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.
Height from the seat
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.
