What is the standard for the service life of auditorium seats?

The service life of auditorium seats is an important standard for measuring the quality of an auditorium chair. We all hope that the auditorium seats can be used for ten or even twenty years. So, what is the standard for the service life of auditorium seats?

Life of sponge:

The seat cushion is the most worn part of the auditorium seat, and the sponge in the seat cushion is the most directly worn. If the weight of the human body exceeds the pressure bearing capacity of the sponge under long-term pressure, it will cause irreversible damage to the sponge and lose its original elasticity.

Life of steel:

Steel is easy to oxidize. If it is not properly maintained, it will rust, causing the auditorium seats to look easy to rust and also affecting the service life of the auditorium seats. Because steel is usually used for standing foot support, if the steel rusts, it will affect the support force of the armrest.

Life of wood:

Because wood is easy to crack or mold, if the place where the auditorium seats are placed is too dry or too humid, the service life of the auditorium seats will be shortened.
