Latex and memory foam refer to different mattress materials, but a product can combine several layers. Compare the full layer list, whether the latex is natural or synthetic, and what any certification actually covers.
Material names describe part of a mattress, not always the full construction. Check each layer and the scope of any certification before comparing products.
Compare the material descriptions
| Label | What it describes | What to check |
|---|---|---|
| Memory foam | A type of flexible polyurethane foam | Which layers contain it and whether the maker lists foam certification |
| Latex foam | Foam made from latex, with source and blend varying by product | Natural, synthetic or blended latex; layer thickness; certification scope |
| Hybrid mattress | A combination of materials, often including a coil unit | Full layer list, cover materials and base construction |
CertiPUR-US explains that its program applies to flexible polyurethane foam, including foam used in mattresses, rather than certifying an entire mattress. For a latex product, check the maker’s documents for the particular latex certification and the layer it covers.
A product-page checklist
- Open the full construction or layer-by-layer description.
- Record the material and thickness of every layer.
- Check whether “latex” means one layer or the full mattress core.
- Read what a certification covers: foam, latex material, textile, finished product or manufacturer.
- Compare dimensions, cover materials, care instructions and return terms separately from the material label.

Common questions
Does a mattress labeled latex contain only latex?
A mattress can combine latex with other foams, fibers or coils. Read the full layer-by-layer materials list.
Does CertiPUR-US certify a whole mattress?
No. The program says its certification applies to flexible polyurethane foam, not the entire mattress or company.
Is latex always organic?
No. Check whether the maker identifies the latex as natural, synthetic or a blend, and verify the specific certification claim.
