Does the auditorium chair you purchased meet the needs of the user?
1. Sitting on the auditorium chair and watching the stage: when you close your eyes, then gradually open your eyes, just right to see the stage or the front, the seat will be uncomfortable if it is too high or too low, so you need to make corresponding adjustments to reduce the neck Muscle strain.
2. The hips are close to the back of the chair, the body will not shrink into a ball, and the burden on the back can be minimized.
3. With your hips close to the back of the chair, try to see if your clenched fist can pass through the space between the back of your calf and the front of the chair. If you can't do it easily, then the chair is too deep, you need to adjust the back of the chair forward, put a cushion or change a chair.
4. Check whether your fingers can slide freely under the thighs and at the front end 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's width between your thighs and the front of the auditorium chair, raise the height of the chair.
5. Under the premise of sitting comfortably, adjust the height of the armrest so that the upper arm is lifted slightly at the shoulder.
