The optimal height of an office chair
For office workers, a comfortable office chair can relax the tired body better. However, the most important thing is the appropriate height of the office chair. What is the best height of the office chair? Everyone's height and shape are different. Not the same, we have to choose the height of the office chair according to our own factors. Let me tell you how much the height of the office chair is best!
Starting from working hours, we need to sit on office chairs and work all day long. If we do not have a proper sitting posture, it will affect our health in the long run. Therefore, it is very important to have a correct sitting posture and a suitable seat height .
The height of an office chair refers to the vertical distance from the seat surface to the ground. If the seat surface has a receding or concave arc shape, the seat height refers to the vertical distance from the center point of the front edge of the seat to the ground. The appropriate height of the seat varies according to the height of the individual. If the seat height is too high, the feet will hang in the air and cannot touch the ground, and the weight will compress the blood vessels of the thighs, hindering the blood circulation of the whole body, which will easily cause fatigue and numbness in the legs; if the seat height is too low, the calves need to support the pressure from the thighs. If it grows, it will cause upper body soreness and discomfort.
The height of the best office chair is the height from the calf socket to the sole of the foot plus the heel thickness of 25-35mm, and then minus the 10-20mm activity margin, that is: H1 (height) = calf socket height + heel thickness - appropriate gap. The actual seat test is to sit in front of the table, place your hands on the table, and your elbows should be bent at exactly 90 degrees.
The height of tables and chairs also has standards in the world, as follows: the national standard GB3326-1997 stipulates that H1 (seat height) is 400-440mm, and the size difference S is 10mm. The maximum height of the soft seat is 460mm (excluding the sinking of the seat). The height of the sofa seat can be lower, so that the legs are stretched forward and the backrest is tilted back, which is conducive to the natural state of the spine. The seat height of the sofa is generally 360-420mm.
Now, most office chairs have the function of automatic adjustment, but for those office chairs that cannot be adjusted in height, we can also flexibly change the height we sit on. Put something on the top, if the seat is high, we can put something under the feet, so that two right angles can be guaranteed.
