Definition of Discoloration

Meaning of the Term as it Pertains to Mattresses

What is Discoloration?

Discoloration refers to when a mattress changes to a different, less attractive color. The process occurs gradually over time when exposed to light giving exposed materials a yellow hue. Sunlight, as opposed to indoor light, tends to speed up the discoloration process. Though visually unappealing, discoloration does not affect mattress performance or durability.

Individuals who want to prevent mattresses from discoloring should keep mattress covers on underneath bedding. Quality covers help protect mattresses even further. Some premium memory foam mattress manufacturers keep coloration in mind when designing mattress. To fight against the unattractive "block of cheese" image that old memory foam casts on the memory foam industry, many quality manufacturers produce foams that maintain clean white appearances over time.
