Definition of Fatigue

Meaning of the Term as it Pertains to Mattresses

What is Fatigue?

Also see coil fatigue: when a mattress's weight supporting capacity diminishes. Generally, lower-quality mattresses experience fatigue after repeated use over several years. Both innerspring and foam mattresses can experience fatigue. Innerspring mattresses are more prone to noticeable effects of fatigue. Sagging and increasing discomfort can indicate diminishing support capability.

High-quality innerspring and foam mattresses usually do not experience noticeable fatigue. Name brands use durable materials, which provide consistent support, even after years of use. Weight loads above the capacity of a bed can cause added strain on a mattress, which causes materials to soften and the mattress to experience fatigue early.
