12 Inch Full Hybrid Mattress in a Box, Firm Pocket Spring Gel Foam

• Extra Firm Feel – Designed specifically for sleepers who need extra support, our extra firm full size mattress delivers a high level of stability that prevents excessive sinking. Ideal for back and stomach sleepers, as well as those with higher body weight, this firm full size mattress promotes proper spinal alignment and reduces pressure on the lower back. Wake up feeling refreshed without the morning aches. Engineered for those who prioritize support and durability.
• This Pocket Coil System – Our firm mattress features individually encased pocket coils that respond independently to your body's pressure points. The coils are reinforced with heavier-gauge steel in the center third to provide targeted lumbar support where you need it most. This firm mattress full construction ensures long-lasting durability and minimizes motion transfer, so you and your partner can sleep undisturbed. Experience the stability of a full mattress firm that truly delivers on its promise of support.
• Enhanced Pressure Relief - To complement the firm coil support, we've added layers of high-density comfort foam that cushion without sacrificing firmness. These foam layers contour slightly to relieve pressure on hips and shoulders while maintaining the extra firm foundation. The result is full size mattress that feels supportive yet comfortable. Delivering the perfect balance of stability and pressure relief for restorative sleep, even for those who require maximum support.
• This Edge Support – The perimeter of this extra firm full mattress is fortified with high-density foam encasement, creating a rigid edge that won't collapse when you sit or sleep near the side. You get more usable sleep surface and can confidently get in and out of bed without feeling like you'll roll off. This reinforced design enhances structural integrity for years of reliable use. Ideal for couples or anyone needing edge-to-edge support.
• Breathable Design & Easy Setup – Despite its firm construction, this firm full mattress in a box promotes airflow through the open coil structure and a breathable knit cover, helping to regulate temperature throughout the night. Plus, it's compressed and shipped in a box for convenient delivery—simply unbox, unroll, and the mattresses will expand to fully regain its shape within 24–48 hours (Size dimensions: 75" L x 54" W x 12" H). Compatible with most bed frames, platform beds, slatted bases, and box springs.
