COOLING HYBRID FOR HOT SLEEPERS: This advanced hybrid mattress combines a breathable coil system with a GlacioTex cool-to-the-touch cover and copper-infused CopperFlex memory foam to actively pull heat away from the body and promote airflow all night long. This is ideal for hot sleepers. TARGETED LUMBAR RELIEF: Individually encased coils work with zoned lumbar support to provide reinforced lower-back support, promote proper spinal alignment, and help reduce back and joint discomfort without sacrificing comfort. RESPONSIVE, MEDIUM-FIRM COMFORT: VariFlex IQ memory foam contours to your body while maintaining responsiveness, limiting motion transfer and preventing the “stuck” feeling common in all-foam mattresses. Medium-firm feel (7/10). STRONG EDGES & MOTION ISOLATION: The hybrid coil core delivers durable support across the entire mattress, enhanced edge stability, and reduced motion transfer—ideal for couples and combination sleepers. IMPROVED SLEEP QUALITY: With a 7-layer, 14” hybrid design, this mattress delivers deep pressure relief, long-lasting support, and advanced cooling—premium hybrid performance designed for hot sleepers at an exceptional value. CERTIFIED SAFE MATERIALS: This bed in a box mattress is Fiberglass-free, GREENGUARD Gold certified, and made with CertiPUR-US foams. Each mattress is carefully assembled in our own Arizona facility and delivered right to your door. We want you to be happy with your mattress and that's why we offer a 120 night sleep trial.
