Definition of Box Spring

Meaning of the Term as it Pertains to Mattresses

What is a Box-Spring?

A flat, spring-filled base, a box-spring is used to support a mattress. Consisting of wood construction and cloth covering, box-springs provide several key benefits for mattresses. Primarily, box-spring foundations absorb shock and reduce the nightly wear and tear on mattresses. A box-spring also raises the height of the sleep surface to make it easier to get in and out of bed. Manufactures even produce box-springs with different heights, such as standard and low profile versions. Using a box-spring also protects a mattress's warranty, as many manufactures require mattresses to be supported by box-springs in order warranty claims to be filed.

The Better Sleep Council, a non-profit organization devoted to educating the public about healthy sleep, suggests that a box-spring is just as important as a mattress. The council also advises that individuals purchase new box-springs along with new mattresses. Box-springs always need to match the length and width of accompanying mattresses. Larger beds may use two twin box-springs as foundations.
