How to adjust the correct height of the net chair

Many people's office chairs are not up to the standard, so they can't free their bodies from low back pain. So, how can we adjust to the "best state"?

First, adjust the desk or workbench to the appropriate height according to the nature of the work. Because different desk heights have different requirements for the placement of seats, and sometimes even need to change a seat. Once the height of the desk is fixed, the height of the net chair can be adjusted according to the "reference" of each part of the body.

Elbow: on the premise of comfortable sitting, the closer the elbow is to the table, the better, so as to ensure that the upper arm is parallel to the spine. Put your hand on the surface of the workbench (such as notebook or keyboard), and adjust the height of the seat up and down to ensure that the elbow is at a right angle. At the same time, adjust the height of the armrest so that the upper arm happens to be lifted slightly at the shoulder.

Thigh: check whether your fingers can slide freely under your thighs and at the front of the chair. If the space is too tight, you need to add an adjustable footrest to support your thighs. If there is a finger width between your thighs and the front of the chair, raise the height of the chair.

Leg belly: with the hips close to the back of the chair, try whether the clenched fist can pass through the gap between the back of the leg belly and the front of the chair. If you can't do it easily, the chair will be too deep. You need to adjust the back of the chair forward, pad a cushion or change a chair.

Back waist: when you feel tired, don't shrink into a ball in the chair, which will increase the pressure on the back waist and intervertebral disc. Keep your hips close to the back of the chair. It's best to put a cushion so that your back can bend slightly, so that your body won't shrink into a ball when you're tired, and the burden on your back can be minimized.

Sight height: close your eyes, and then slowly open your eyes. Your sight should fall in the center of the computer monitor. If the monitor position is too high or too low, you need to make corresponding adjustments to reduce neck muscle strain.

Of course, sitting still for a long time is not good for your body, so remember to get up and move for at least one to two minutes every half hour. Even simple activities like stretching or going to the bathroom are OK. If possible, walking slowly for 20 minutes can not only reduce the pressure on the spine, but also promote blood circulation, so as to transport nutrients to all parts of the spine.
