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 Beautyrest brand hub or our mattress types guide, which explains how foam, latex, hybrid, and innerspring builds differ in feel and durability.
Beautyrest signature technology
- Pocketed Coil Technology: Individually wrapped coils that move independently, the construction Simmons pioneered and still builds its lineup around.
- T3 / T2 Pocketed Coil (Black): Higher-tension, multi-strand coils in Beautyrest Black models for extra support under heavier load points.
- InfiniCool / RightTemp Layers: Surface cooling layers and fibers used on upper models to pull heat away from the sleep surface.
