Use frequency: If used less frequently, it will last a long time. The mattress in the less-used guest room will last much longer than the mattress you sleep every night.
Bodyweight: Similarly, the smaller your body, the lower its compression; the higher pressure causes the mattress to be wearing out sooner, so that the lighter the body, the longer its lifespan.
Activity and use: The more you use it, the more it gets worn down after sitting on it. It involves placing hard or blunt items on the couch or dining or sleeping. Dispositions and other harm may weaken the mattress.
Cleaning: This can improve the life of your mattress, as it not only eliminates bacteria but dust mites and insects which cause harm.
