Foam mattresses may combine several foam types and densities in separate layers. Compare the model’s layer description, certifications and warranty rather than relying on a single label.
Layer chart
| Material label | How it appears in product descriptions | Check before buying |
|---|---|---|
| Memory foam | A viscoelastic foam layer, sometimes listed as comfort foam | Layer location, thickness, cover and included support layers |
| Polyfoam | A polyurethane foam layer used in several parts of a mattress | Whether the maker identifies it as comfort, transition or support foam |
| Latex foam | A latex layer, with material and process varying by model | Natural or blended material statement, certification and care directions |
| Hybrid construction | Foam layers combined with a coil unit | Coil count or layout, edge structure and layer materials |
Tempur-Pedic and other manufacturers publish model-specific construction descriptions. Compare the exact product’s layer list and any certification record. This guide describes mattress materials only. If pain, sleep symptoms or another health concern affects your choice, ask your doctor.

Common questions
Is memory foam the only foam in a mattress?
No. A mattress can combine memory foam, polyfoam, latex or other layers. Check the maker’s material breakdown.
Does a certification describe every mattress layer?
A certification applies to its stated scope and product. Read the certifier’s listing and the maker’s model details.
Can I compare firmness ratings between brands?
Use each maker’s own scale and construction details because firmness labels are not a universal measurement.
