The Halston Firm is where the Jamison Autograph Series reaches its upper echelon of performance. At 14 inches, this mattress introduces UltraCool™ Fabric — Jamison's most advanced cooling cover, engineered to feel noticeably cooler to the touch than standard mattress fabrics and to maintain that temperature advantage throughout the night. MemoryQuilt™ Foam w/Gel in the quilt layer adds an initial adaptive softness at the surface, while the dual upholstery system of ComfortFirm™ Foam and LuxFirm™ Foam creates a layered, supportive firmness that doesn't sacrifice body contouring. LuxFirm™ is a high-density performance foam that provides the kind of stable, even support preferred by healthcare professionals and back pain sufferers. The UltraEdge Secure™ Individually Wrapped Coil foundation completes the picture with zoned coil technology that delivers different levels of support to different body zones. 10-year full warranty.
