Layer breakdown
Polyfoam comfort layer
1.25″ thick · 1.5 lb/ft³ density
At 1.5 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 · 1.8 lb/ft³ density
1.8 lb/ft³ foam runs light, but a 1″ slab like this is too thin to drag durability down.
Memory foam transition layer
1″ thick · 7 lb/ft³ density
Measured at 7 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″ 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.
Coil transition layer
0.75″ thick
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
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 · 1.8 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.
