Layer breakdown
Memory foam comfort layer
3″ thick · 3.3 lb/ft³ density
Measured at 3.3 lb/ft³ — solid memory foam for average-weight sleepers, though heavier (200 lb+) sleepers would want closer to 3.5 lb/ft³ here.A memory-foam layer this thick tends to hold body heat — worth knowing if you sleep hot.
Polyfoam transition layer
3″ thick · 1.7 lb/ft³ density
Measured at 1.7 lb/ft³ — solid polyfoam for average-weight sleepers, though heavier (200 lb+) sleepers would want closer to 2 lb/ft³ here.
Polyfoam support core
6″ thick · 1.8 lb/ft³ density
Measured at 1.8 lb/ft³ — clears the ~1.8 lb/ft³ durability bar we'd hold polyfoam to even under heavier (200 lb+) sleepers.
