Layer breakdown
Polyfoam comfort layer
1″ thick · 2.8 lb/ft³ density
Measured at 2.8 lb/ft³ — high-density foam like this resists softening and body impressions, one of the strongest longevity signals in a build.
Memory foam transition layer
2″ thick · 1.9 lb/ft³ density
At 1.9 lb/ft³ this foam sits under the ~2.7 lb/ft³ we'd want from memory foam — low-density foam tends to soften and take body impressions sooner, especially under heavier sleepers.A memory-foam layer this thick tends to hold body heat — worth knowing if you sleep hot.
Polyfoam transition layer
2″ thick · 1.5 lb/ft³ density
At 1.5 lb/ft³ this foam sits under the ~1.6 lb/ft³ we'd want from polyfoam — low-density foam tends to soften and take body impressions sooner, especially under heavier sleepers.
Polyfoam transition layer
4″ thick · 1.6 lb/ft³ density
Measured at 1.6 lb/ft³ — solid polyfoam for average-weight sleepers, though heavier (200 lb+) sleepers would want closer to 2 lb/ft³ here.
Polyfoam support core
6.5″ thick · 1.6 lb/ft³ density
Measured at 1.6 lb/ft³ — solid polyfoam for average-weight sleepers, though heavier (200 lb+) sleepers would want closer to 1.8 lb/ft³ here.
