Adjustment methods of different types of office chairs
We can see that there are two handles under the office chair, and one of the handles is used to adjust the height of the chair. We only need to hold this handle and lift it up, and you will find that the office chair will be adjusted upwards. If you press down, the corresponding office chair will go down, so we only need to sit on the office chair and adjust the height according to our own needs. It's not as complicated as you think, you can try it yourself.
Matters needing attention in adjusting the height of the office chair:
Adjusting the height of the office chair is not that complicated, you only need to master its operating lever, and then adjust it according to your own needs, but we also need to pay attention to several aspects when adjusting.
1. It should be adjusted according to the height of the desk and chair, and at the same time according to your own height. Generally speaking, when we sit on the office chair, people's eyes should be at the same level as the computer, so that we will not be too tired when looking at the computer. .
2. The height of the adjustment should also be moderate, not too low, so that people will get stuck on the office chair. But it can't be too high, or the eyes will be very difficult. Afterwards, we must ensure that we can sit in a good posture, otherwise we will be hunched over, bending over all day at a young age, and the image will be very bad.
3. I encountered some chairs that were not easy to adjust and needed to be replaced. We also need to have a good environment when we come to work, and we have to sit for a whole day. If we can’t adjust it, we must not force ourselves, and we need to replace it.
The adjustment of different types of office chairs:
1. Pneumatic office chair
Pneumatic office chairs will have 1 or 2 operating levers under the chair seat, and the height adjustment mainly depends on the weight of the human body.
When no one is sitting on the office chair, lift up the operation lever, and the high-pressure gas inside the air lever will rebound after being pressurized, and the seat will rise.
When someone is sitting on the office chair, the operating rod is lifted up, the rebound of the high air pressure in the air rod is resisted, and the seat seat is lowered accordingly.
If there are two joysticks under the seat of the office chair, one is to adjust the height of the chair, and the other is to adjust the angle of the back of the chair. If you don't know the difference, just try it out before adjusting.
2. Spiral Office Chair
In the case of a spiral office chair, turning the knob clockwise will lower the chair, and turning the knob counterclockwise will raise the chair.
3. Manual adjustment
Of course, there are also some old-fashioned office chairs that are neither pneumatic nor spiral, but have a fixed screw under the backrest, which needs to be loosened and adjusted to a suitable height with tools, and then tightened and fixed. It is a bit similar to the lifting mode of the seat cushion of a bicycle.
The suitable height of the office chair:
Everyone's height is different, and the height of the desktop is also different. Therefore, the specific height of the office chair needs to be adjusted according to its actual situation.
However, the correct table and chair height should enable people to maintain two basic verticals when sitting:
One is that when the feet are flat on the ground, the thigh and calf can be basically vertical. At this time, the front edge of the seat surface cannot form pressure on the lower plane of the thigh.
Second, when the two arms hang down naturally, the upper arm is basically perpendicular to the forearm, and the height of the table should just touch the lower plane of the forearm. This allows people to maintain correct sitting and writing postures.
