COMFORT WITH PRESSURE RELIEF: Designed for side sleepers, this medium firm king mattress combines comfort cushioning with supportive pocket coils to create the perfect balance of comfort and support. It helps reduce pressure buildup in the shoulders and hips while maintaining proper spinal alignment, allowing you to enjoy a comfortably supported sleep experience night after night.
HYBRID CONSTRUCTION – 60% MORE STABLE SUPPORT: this medium firm king hybrid mattress combines high-density comfort layers with a reinforced pocket coil system to create a more stable sleep foundation. The responsive support helps prevent sagging over time while delivering consistent firmness and full-body support.
COOLER SLEEP WITH ENHANCED AIRFLOW: Stay comfortably cool throughout the night with a breathable knit cover, cooling gel-infused foam, and airflow-promoting pocket coils. The open hybrid design allows heat and moisture to dissipate more efficiently than traditional foam mattresses, helping create a fresher, drier, and more temperature-balanced sleep environment.
PREMIUM MOTION ISOLATION FOR UNDISTURBED SLEEP: Built with individually wrapped 2.0mm reinforced steel coils, this king hybrid mattress effectively absorbs movement and reduces motion transfer between sleep partners. Ideal for couples, it helps ensure a quiet, uninterrupted night's rest—no more being disturbed by your partner's tossing and turning.
CERTIFIED SAFE, FIBERGLASS FREE : Sleep with confidence knowing this king mattress is made with CertiPUR-US certified foams, OEKO-TEX certified fabrics, and fiberglass-free materials while meeting CFR1633 flammability standards. Backed by UniPon's 40+ years of sleep expertise, every mattress includes a 365-night trial and lifetime customer support for long-term peace of mind.
