What are the design characteristics of auditorium chairs and theater chairs and the material requirements for theater chairs?

It is very important whether the filling and cloth inside the auditorium chair are close, flat and comfortable. Whether there are creases at the joint of the armrest, seat and back needs to be carefully checked. When purchasing, you should sit on the chair and feel whether it is comfortable or not. Stability, angle is not reasonable, how comfortable is. I am worried that the material will affect the usability and life of the chair, so the durable strength, elasticity and density of the elastic material must be good enough and high enough. When purchasing, you can ask the company for relevant instructions to ensure the quality of the product.
