What is a Mattress made of?
Steel springs or polyurethane foam, comfort layers, and a legally required fire barrier under the quilted cover.
A mattress is one of the few household products with a federal flammability standard behind its construction: since 2007, US mattresses have had to survive a 30-minute open-flame test, which is why almost every mattress has a barrier fabric that manufacturers rarely mention. The other thing worth knowing is that firmness is not durability — a mattress usually fails because the comfort layers above the core compress permanently, leaving a body impression, long before the springs give out. Memory foam is a viscoelastic polyurethane developed from NASA-funded aircraft seat research in the 1960s, and its temperature sensitivity is intrinsic: the same foam is noticeably firmer in a cold room.
Component by component
| Part | Material | Why that material |
|---|---|---|
| support core | pocketed steel coils, continuous coils, or high-density polyurethane foam | Pocketed coils move independently so one sleeper moving does not transmit through the bed; foam cores are lighter and silent. |
| comfort layers | viscoelastic memory foam, latex foam or gel-infused polyurethane | Memory foam softens with body heat and spreads pressure, at the cost of sleeping warm and being slow to respond. |
| fire barrier | a knitted rayon-silica or modacrylic sock beneath the cover | US mattresses must survive an open-flame test under 16 CFR 1633, and a barrier layer is how that is met without soaking foam in chemicals. |
| cover | quilted polyester or polyester-cotton ticking | It has to survive years of abrasion and be stretchy enough not to fight the foam underneath. |
| edge support | a foam rail or a heavier gauge perimeter coil | Without it the edge collapses when you sit on it and the usable sleeping width shrinks. |
