Layer breakdown
Memory foam comfort layer
3″ 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.A memory-foam layer this thick tends to hold body heat — worth knowing if you sleep hot.
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
1″ 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.
