In auditoriums, cinemas, theaters and other places, we can always see that the seats there are very different in appearance and structure from ordinary chairs. This kind of seat is the auditorium chair commonly used in these public places. The structure of the auditorium chair is slightly more complicated than that of ordinary chairs. It is mainly composed of four parts: seat, back, armrests and feet. So how to distinguish the pros and cons of the appearance of auditorium chairs?

1. Wiping method: Use stain removal oil to wipe the surface of the auditorium chair to see if there is fading or color loss on the surface of the seat. This method can effectively avoid old seats that have been recolored.

2. Smell method: After a certain process, a seat will generally not have an irritating smell. However, if it has too much solvent smell and paint smell, it will definitely be unqualified.

3. Observation method: Use a magnifying glass with a magnification effect of 30 times or more to observe whether there are some small holes on the surface of the seat. If there are, it means that the auditorium chair has good air permeability, otherwise it means poor air permeability.
