Layer breakdown
Memory foam comfort layer
1.5″ 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.
Memory foam transition layer
1.5″ thick · 5 lb/ft³ density
Measured at 5 lb/ft³ — high-density foam like this resists softening and body impressions, one of the strongest longevity signals in a build.
Memory foam transition layer
1.5″ 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.
Polyfoam transition layer
0.5″ 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 · 13.5-gauge steel
13.5-gauge steel — thicker wire than most, built to carry heavier sleepers without giving up support.An open coil core is the best airflow a mattress can have — body heat vents out instead of building up.
Polyfoam base layer
1″ 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.
