This makes it ideal for sleepers who tend to overheat at night.
High-Density Support Foam Base
The bottom support layer:
Prevents excessive sinking
Improves spinal alignment
Adds structural durability
Makes it suitable for back, side, stomach, and combination sleepers
Unlike single-layer toppers that may feel too soft or unstable, this hybrid system maintains both comfort and support.

✔ Back pain sufferers
