Casper Sleep Original Foam Hybrid 11" Medium Firm Memory Foam Mattress

11-Inch Medium Cooling Hybrid Mattress

Enjoy the perfect balance of support, pressure relief, cooling, and responsive comfort with this premium 11-inch hybrid mattress. Combining three layers of resilient memory foam with individually pocketed springs, it provides a supportive yet comfortable sleep surface with enhanced airflow.

The zoned support system is designed to provide softer cushioning beneath the shoulders and firmer support around the hips, waist, and lower back, helping promote balanced spinal alignment and full-body support.

Responsive pocket coils add gentle lift while allowing air to circulate through the mattress. Combined with breathable open-cell foam and a flexible knit cover made with recycled materials, the design helps create a cooler and more comfortable sleep environment.
