Performance breakdown
Edge Stability
Steel-encased perimeter prevents sagging and maximizes usable sleeping surface area.
Motion Isolation
Hybrid construction dampens movement well, though coils still offer slight bounce.
Contouring Support
Multi-layer foam layers adapt precisely to body pressure points for alignment.
Adjustable Base Compatibility
Engineered specifically to flex and conform perfectly with motorized bed frames.
Firmness Consistency
High-density materials maintain a reliable, supportive feel across the entire mattress.
Setup Convenience
Heavy weight makes maneuvering the box difficult before the 48-hour expansion.
