TWIN XL Size 12-Inch Medium Hybrid Mattress in a Box, Euro Top with ActiveCool Gel Memory Foam for Pressure Relief & Motion Isolation, Fiberglass-Free, CertiPUR-US Certified

The 12 Inch Hybrid Mattress is your gateway to transformative sleep and superior spinal support. This premium 12 inch hybrid mattress combines individually wrapped pocket coils with multiple layers of high-density memory foam to deliver the perfect balance of responsive support and cloud-like comfort. At the heart of this 12 inch hybrid mattress lies a sophisticated engineering approach—hundreds of independently encased steel coils work in concert to provide targeted pressure relief and motion isolation, ensuring you sleep undisturbed even when your partner tosses and turns. The top comfort layers of gel-infused memory foam and breathable transition foam gently cradle your body's natural curves, releasing tension from your shoulders, back, and hips accumulated throughout the day. What sets this 12 inch hybrid mattress apart is its commitment to temperature regulation and sleep hygiene. The quilted knit cover features moisture-wicking properties, while the gel memory foam layer actively dissipates heat to prevent the overheating common with traditional all-foam beds. The 12 inch hybrid mattress earns its profile name through thoughtful layering—transition foam creates a pressure-relieving buffer zone between your body and the supportive coil base, maintaining healthy spinal alignment whether you prefer sleeping on your side, back, or stomach. Reinforced perimeter edge support maximizes the usable sleep surface of your 12 inch hybrid mattress, preventing roll-off and making it easier to get in and out of bed. This 12 inch hybrid mattress is purpose-built for the American lifestyle, catering to busy professionals seeking hotel-quality rest, couples requiring motion separation, and anyone transitioning from an aging innerspring or sagging foam mattress. The 12 inch hybrid mattress carries CertiPUR-US certification, guaranteeing the absence of formaldehyde, heavy metals, and harmful flame retardants—peace of mind for families with children or sensitive sleepers. Delivered directly to your door in a compact, vacuum-compressed box, this 12 inch hybrid mattress navigates narrow staircases, tight hallways, and apartment elevators with ease. Once unboxed, your 12 inch hybrid mattress expands to its full 12-inch height within 48-72 hours, ready to deliver restorative sleep night after night.
