Layer breakdown
Polyfoam comfort layer
0.75″ thick · 1.5 lb/ft³ density
1.5 lb/ft³ foam runs light, but at 0.75″ it's a surface quilt — too thin to drag durability down.
Memory foam transition layer
1″ thick · 2.5 lb/ft³ density
2.5 lb/ft³ foam runs light, but a 1″ slab like this is too thin to drag durability down.
Memory foam transition layer
1.5″ thick · 2.4 lb/ft³ density
At 2.4 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.
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
0.75″ thick · 1.5 lb/ft³ density
1.5 lb/ft³ foam runs light, but a 0.75″ slab like this is too thin to drag durability down.
Polyfoam support core
6″ thick · 1.5 lb/ft³ density
Measured at 1.5 lb/ft³ — solid polyfoam for average-weight sleepers, though heavier (200 lb+) sleepers would want closer to 1.8 lb/ft³ here.
