Lifetime of sponge
The greatest wear of the auditorium chair is the seat cushion, and the sponge wear inside the seat cushion is the most direct. Under long-term pressure, if the weight of the human body exceeds the bearing capacity of the sponge, it will cause irreversible damage to the sponge, and it will lose its original elasticity.
Life of steel
Steel is easy to oxidize, if not well maintained, it will rust, resulting in the auditorium chair looks easy to rust, and also affects the service life of the auditorium chair. Because steel is usually used in the foot support, if the steel rusts, it will affect the support of the foot.
Life of wood
Because the wood is prone to cracking or mildew, if the place where the auditorium chair is placed is too dry or too wet, the service life of the auditorium chair will be shortened.
