What’s under the covers?
Part of your mattress education is understanding the different components of your sleep set. We all know what a mattress and a box spring are, but what’s really going on inside? And most important, how does what’s inside help you sleep? Once you know what goes into building a Serta® mattress, you’ll be able to select the one that’s right for you.
What's in a Serta Innerspring Mattress?
A: Comfort Layers
The feeling you get when you first lie down on a mattress comes from the foams and fibers used in the upholstery layers above the innerspring. Serta mattresses use special fibers complemented by responsive, body-conforming foams to ease pressure points along the body. These mattress comfort layers reduce tossing and turning, promoting a better night’s sleep.
Comfort choices vary by mattress collection. Many Serta mattresses offer a variety of comfort choices that allow you to choose your ideal sleeping surface, such as Firm, Euro Top, Pillow Top, and Super Pillow Top mattresses.
B: Innerspring Support System
Serta makes its innerspring systems from twice-tempered steel. The “coil count,” or number of coils in a mattress, varies from manufacturer to manufacturer. Of course, it also depends on size of the mattress. However, for comparison, actual coil count is generally based on a queen-size mattress. (In other words, twin mattresses will have fewer coils while kings will have more.)
You might have heard a rumor that the more coils in an innerspring, the more supportive the mattress will be. While this can be true, coil count is not nearly as critical today as it once was. These days, the combination of coil count, coil gauge and the construction of the coils is a much more important factor in determining the overall comfort and support of the mattress. For example, Serta’s continuous coil innerspring systems can provide greater support than other coil systems with similar coil counts because of the unique construction.
The mattress foundation is the “base” of the sleep set and works in unison with the mattress to provide proper support and durability. The foundation, or box spring, is designed to complement the performance of the mattress. Purchasing just the mattress or foundation alone does reduce the overall durability and longevity of your mattress set.
The federal mattress flammability standard, 16 CFR Part 1633, went into effect on July 1, 2007. Fire tests show that, in many cases, a 1633-compliant mattress that is used with a pre-standard box spring will fail the standard’s testing requirements. So mixing a new mattress with an old foundation may pose a safety risk to consumers. The mattress and foundation should both be replaced, as a set, at the same time.
