Construction
This model's name doesn't encode its materials, and we haven't tested it in our lab.
For construction detail, start with the Sealy brand hub or our mattress types guide, which explains how foam, latex, hybrid, and innerspring builds differ in feel and durability.
Sealy signature technology
- Posturepedic Technology: A reinforced center-third coil zone engineered to limit sag where the hips load the mattress hardest.
- Response Pro Encased Coils: Individually wrapped coils with a firmer perimeter for edge support and easier bed exit.
- Chill / Air Cool Covers: Cover and comfort-layer treatments on upper models to reduce trapped heat over an all-foam surface.
