This 13-inch hybrid mattress in classic gray offers firm support with a tight top design, sized Twin Extra Long for bedroom sleeping. Advanced cooling technologies work to keep you comfortable: phase-change material absorbs and releases heat, while gel-infused memory foam contours to your body and dissipates warmth instead of storing it. The pocketed coil system with 1000 individually wrapped coils responds to movement, delivering targeted support and reduced partner motion transfer. A reinforced perimeter provides 360-degree edge stability, making the entire surface usable. Inside, reinforced center-third support enhances lumbar alignment right where you need it, while resilient foam helps maintain the mattress’s shape for lasting support. At 13 inches thick, this hybrid mattress combines cooling comfort with firm support so you wake feeling refreshed and rejuvenated. The classic gray cover completes a clean look for any bedroom.
