Experience cool, supportive comfort with this mattress. Its breathable knitted cover and air-sensing gel memory foam actively regulate temperature by promoting airflow and pulling heat away. The foam contours to relieve pressure points at shoulders, hips, and back, while the resilient high-density sponge core provides firm, consistent support for proper spinal alignment. Featuring a removable, machine-washable cover and anti-slip bottom for easy cleaning and stability, it's safely constructed with a fiberglass-free, fire-retardant inner cover and double-certified (CertiPUR-US & OEKO-TEX Standard 100) foams. Delivered compressed in a box, simply unbox, unroll, and allow 24-72 hours to expand to its medium firm feel, suitable for all sleeping positions.
