Purple 4 Mattress Review: Archived Hands-On Testing Restored
The Purple 4 is discontinued, but the original review contained extensive real testing of the deepest Purple Grid model and should not have been replaced by a tiny archive notice.
Deepest Purple Grid
The Purple 4 used four inches of Purple’s hyper-elastic grid over specialized foam and pocketed coils. That made it the plushest, deepest-contouring model in the old Purple hybrid lineup.
Sinkage and side sleeping
Our 14-pound bowling ball sank deeply into the grid, matching the weightless, cradled feel we experienced on our side. Among the old Purple hybrids, this was the strongest side-sleeper option.
Bounce without excessive motion transfer
The grid recovered almost instantly and the coil unit added true spring response. Despite that bounce, the mattress still controlled cross-bed motion surprisingly well.
Cooling
The open-grid structure allowed continuous airflow through much of the comfort layer, making the Purple 4 one of the cooler-feeling mattresses we tested in that era.
Current-shopping note
Purple discontinued the Hybrid Premier 4/Purple 4. This page is preserved as a historical review; current Purple collections use different names and constructions.
