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.
Memory foam transition layer
1″ thick · 3.6 lb/ft³ density
Measured at 3.6 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
1.5″ thick · 2.2 lb/ft³ density
At 2.2 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
1″ thick · 1.5 lb/ft³ density
1.5 lb/ft³ foam runs light, but a 1″ slab like this is too thin to drag durability down.
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 · 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
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.
