About This Product

Experience a cooler, more restorative night’s sleep with the Alwyn Home Kristi Cooling Gel Memory Foam Mattress. Designed to combine contouring comfort with reliable support, this mattress adapts to your body’s natural curves while helping to relieve pressure on sensitive areas like the shoulders, hips, and lower back. The gel-infused, open-cell memory foam promotes airflow and temperature regulation, helping reduce heat buildup throughout the night. Whether you tend to sleep hot or share your bed with a partner, the advanced motion-isolating design helps minimize disturbances so you can enjoy uninterrupted rest. Built with a durable high-density support core, the Kristi mattress maintains stability and shape over time. Choose the firmness level that fits your sleep style: • 8" Firm – Structured support with minimal sink-in, ideal for back and stomach sleepers. • 10" Medium Firm – Balanced comfort and support for side, back, and combination sleepers. • 12" Soft Plush – Deeply cushioning comfort designed for side sleepers who prefer a cradling feel. Finished with a removable, antimicrobial cover and delivered conveniently in a box, this mattress makes upgrading your sleep simple. Just unbox, unroll, and allow 24–72 hours for full expansion. Wake up refreshed. Sleep cooler. Feel supported.
