About this deal

This hybrid mattress is engineered to provide consistent, healthy sleep for a wide range of body types and sleep styles. Its carefully designed multi-layer construction balances pressure relief, spinal support, and breathability to promote all-night comfort. Certified by OEKO-TEX STANDARD 100 and CertiPUR-US, all foam components are tested against over 1,000 harmful substances for a safer sleep environment. High-density gel memory foam contours to the body while resisting sagging, helping relieve pressure on the shoulders, back, and hips. Individually wrapped pocket coils deliver responsive, targeted support and reduce motion transfer for undisturbed rest. Breathable comfort layers and a skin-friendly knit cover enhance airflow and heat dissipation, supporting a cooler sleep experience. Reinforced edges improve stability and usable sleep space, while the non-slip base keeps the mattress securely in place. Built with durable core materials for long-term performance, this mattress is backed by an extended sleep trial and long-term warranty, offering a risk-free way to invest in lasting comfort and support.
