Home should not only have a place for children to study, adults also need to have a place to read and work, about the chair and desk some knowledge, I think we need to know some, the following take a look at it!
On the choice of desk, first of all, we self-check the desk at home, it is likely to be in the look of not useful! The easiest to choose the wrong is the concave desk ~ ~ sit down and check the legs under the table activity area, the area circled in the picture below!
Many families are prone to the problem of the desk is that this activity area is too narrow, so the desk bought is only suitable for children to use. Adults use it, the legs will be firmly stuck in the middle of the seat, there is no room to move.
The place where the legs are placed, the width is less than 500mm, a 170cm person is very inconvenient to use! There is another, is the depth is too short. People sit down, must eight legs. For example, the following picture:
Although the desk below the increase in the partition can be convenient storage, but the partition affects the comfort, people sit down to put the legs placed in the placement of the depth is too small, is the wrong desk design.
I did not realize that a small desk choice, there are so many things to pay attention to.
The problem is, work at home, want to sit comfortably without pressure, how the combination of desk and chair is most suitable?
We answer this question from the perspective of ergonomics. The height of the table is determined by the height of the chair? There is a certain reason, but not very objective, some people have long legs, some people have short legs, but in real life, according to the height of the decision table height has been able to meet the daily needs.
Want to know the most suitable for your table and chair combination, the correct approach is: first decide the height of your chair, and then to sit to decide the height of the desk.
Height of the chair
(1) The height of the chair surface = the height of the knees from the ground.
Adults, look at the following chart:
Adult seat height, that is, sitting on the seat just feet on the ground, family use, you can choose to adjust the height of the seat. Of course, short people can be adjusted through the footrest (foot pad).
Children, you can refer to the following table to choose:
This is our country in 2002, the introduction of a student desk and chair size selection guide table. Very useful oh! In this way, you are not instantly aware of their optimal seat height is how much?
On the purchase of seats, there is another place to pay attention to: the distance from the seat armrests to the arm, can not be too small! In this way, we can freely stretch our arms without constraints when sitting. However, in order to avoid excessive strain on the elbow joint for a long time hanging, it is recommended that we still choose a chair with armrests.
In addition, the spatial distance is also very important!
Seats and other furniture with the time, pay extra attention to the spacing! In particular, the space between the left and right sides of the seat and the back should be at least 810 millimeters, so that it is easy to move our chairs, get up and sit down without difficulty. The picture below is a demonstration of the error!
The correct way to open is:
Pay attention to the seat height, the armrest spacing of the seat, the reserved space of the seat with the furniture, and find a perfect seat, for you, basically a piece of cake. Here's a look at the height of the desk that goes with the seat.
Desk height
How high is the desk to choose in order to be useful and comfortable? Different types of work correspond to different desk heights. Specifically look at the table parameters:
Comparison can be found, girls working at home suitable for 700-740mm or so desktop height of the desk. Tried, indeed, good, such a height, you can make the upper body operating position is most convenient.
After reading the above parameters, if you still feel that you will not choose, it is okay, and then teach you a simple and crude formula.
Assuming you have a normal body proportion, you can directly follow the formula below to choose the right table and chair for you:
(1) Chair height = height * 27% + 2
(2) Desk height = height * 43% + 2
Long legs or short legs of the babies, can be calculated above the height of the upper and lower plus or minus 3 to 5 cm. adjustment. Finished, a set of suitable your table and chairs was born!
Desktop width
After the height of the table and chairs to determine a good, we can not forget to grasp the desk area, some people think that the desktop is the wider the better, in fact, it is not.
How much desk top is the most practical?
On the issue of the size of the desktop area, look at the following figure:
Image description: the number is the size of the label, the upper figure is the imperial feet, the lower figure is the metric system centimeters, we look at the following figures directly. The picture above shows that an average body, desk top length 119.4cm is enough!
A lot of workstations on the market are 1200mm, if the height is normal, are enough, because this is a normal height and weight of the manpower effective action limit range.
Width, not stand up, 50.8cm is the limit of effective action, if you add the placement of other things, can be slightly wider.
This choice allows you to access anything on the table without having to stand up. Now you know, the wider the desktop is not the better it is ~ however, if you have too much stuff and want to increase the storage, you can try to increase the desktop area.
