Layer breakdown
Polyfoam comfort layer
2″ thick · 1.6 lb/ft³ density
At 1.6 lb/ft³ this foam sits under the ~1.8 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 · 2.2 lb/ft³ density
Measured at 2.2 lb/ft³ — clears the ~2 lb/ft³ durability bar we'd hold polyfoam to even under heavier (200 lb+) sleepers.
Coil support core
6″ thick · 14.5-gauge steel
An open coil core is the best airflow a mattress can have — body heat vents out instead of building up.
Polyfoam base layer
2″ 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.
