Layer breakdown
Polyfoam comfort layer
1″ thick · 1.5 lb/ft³ density
1.5 lb/ft³ foam runs light, but at 1″ it's a surface quilt — too thin to drag durability down.
Polyfoam transition layer
1″ 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 transition layer
1″ thick · 2.4 lb/ft³ density
Measured at 2.4 lb/ft³ — clears the ~2 lb/ft³ durability bar we'd hold polyfoam to even under heavier (200 lb+) sleepers.
Polyfoam transition layer
0.75″ 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 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.
Coil support core
8″ thick
An open coil core is the best airflow a mattress can have — body heat vents out instead of building up.
