Layer breakdown
Polyfoam comfort layer
2.5″ thick · 3 lb/ft³ density
Measured at 3 lb/ft³ — high-density foam like this resists softening and body impressions, one of the strongest longevity signals in a build.
Polyfoam transition layer
2″ thick · 1.8 lb/ft³ density
Measured at 1.8 lb/ft³ — solid polyfoam for average-weight sleepers, though heavier (200 lb+) sleepers would want closer to 2 lb/ft³ here.
Polyfoam support core
7.5″ 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.
