Smart Dual Cooling System: Experience scientifically-engineered temperature regulation with Phase Change Material that actively absorbs and releases heat combined with HD CoolFlow Foam's ultra-breathable structure, working synergistically to maintain optimal sleeping temperature throughout the night while preserving firm support integrity.

Multi-Layer Firm Comfort: Our precision-engineered foam system features CoolFlow Plush Foam for breathable surface comfort, CoolFlow Medium Foam for balanced pressure relief, and HD CoolFlow Foam for enhanced cooling - all layered to provide firm yet comfortable orthopedic support without the typical stiffness of traditional firm mattresses.

Reinforced Core Architecture: The ultra-durable foundation combines high-resilience DuraLast Support Foam with 700 individually pocketed coils that provide zoned support where needed most, ensuring proper spinal alignment while effectively isolating motion across the entire sleep surface.

Marvelous Middle® Lumbar Technology: Our clinically-inspired reinforced center-third system delivers 25% increased support density precisely along the lumbar region, dramatically reducing pressure points while maintaining consistent firmness levels across the entire mattress surface.

360° SuperEdge Structural Support: The advanced perimeter system features high-density foam reinforced steel border guards working in unison with the coil system, creating an exceptionally rigid edge that prevents roll-off and effectively expands usable sleep surface by 18% compared to standard firm mattresses.
