Twin Size Mattress in a Box 12 Inch Hybrid Mattress [Enhanced Stability], Medium Firm Feel with Memory Foam and Pocket Springs, Reinforced Edge Support

【Balanced Comfort and Medium Firm Support】 This medium firm hybrid mattress combines responsive memory foam with durable individually wrapped coils to offer a balanced blend of contouring comfort and stable support. Ideal for back, side, and combination sleepers, it helps align your spine and relieve shoulder and back pressure. 【Reinforced Stability and Edge Support】 Enhanced edge reinforcement ensures greater perimeter support, prevents sagging or roll-off, and expands your usable sleep surface. Whether lying near the edge or getting in and out of bed, the mattress provides dependable support and structural durability. 【Quiet Sleep System with Wave Foam】 Individually wrapped coils respond independently to movement and minimize partner disturbance. Combined with wave-shaped foam layers, the mattress absorbs motion and excess noise—creating a quieter, more restful sleep environment. 【Breathable Layers with Safe Materials】 The mattress features breathable knitted fabric and open-cell comfort foam that promote airflow and temperature regulation. Made with carefully selected, safety-tested materials, it’s designed to offer everyday comfort and long-term peace of mind. 【Mattress in a Box with 100-Night Trial】 Compressed and rolled for easy delivery, the mattress fully expands within 48–72 hours after unboxing. It comes with a 100-night risk-free sleep trial and a 11-year limited warranty. Compatible with most bed frames, platforms, and foundations.
