Layer breakdown
Polyfoam comfort 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 2.2 lb/ft³ here.
Memory foam transition layer
1″ thick · 3.5 lb/ft³ density
Measured at 3.5 lb/ft³ — clears the ~3.2 lb/ft³ durability bar we'd hold memory foam to even under heavier (200 lb+) sleepers.
Memory foam transition layer
2″ thick · 2.5 lb/ft³ density
At 2.5 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 · 1.8 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.
Coil support core
8″ thick · 15-gauge steel
An open coil core is the best airflow a mattress can have — body heat vents out instead of building up.15-gauge coils are thinner wire — a softer, springier core, though under heavier sleepers it can give up support sooner.
