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.
Memory foam transition layer
0.5″ thick · 1.8 lb/ft³ density
1.8 lb/ft³ foam runs light, but a 0.5″ slab like this is too thin to drag durability down.
Polyfoam transition layer
1″ thick · 4 lb/ft³ density
Measured at 4 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 · 1.5 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.
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.
Polyfoam base layer
0.75″ 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.
