Comfort – Comfort in a mattress comes from the foams and fibers used in the upholstery layers above the innerspring. Special fibers and responsive body-conforming foams ease pressure points along the body, reducing tossing and turning and giving you a better night's sleep.

Innerspring – The innerspring is made from double-tempered steel coils and provides the support characteristics of the mattress. Innerspring units offer a number of different "coil counts" – the number of coils in the mattress. Actual coil count is generally based on a full-size mattress. Therefore, twin mattresses will have fewer coils while queens and kings will have more. The coil count and wire thickness (or gauge) determine how much support the innerspring offers and its ability to evenly distribute weight..

Foundation – The foundation is the "base" of the sleep set and works in unison with the mattress to provide proper support and durability. The foundation is designed to complement the performance of the mattress. Purchasing just the mattress or foundation reduces the overall durability of the set.
