The Feel This mattress has a medium-firm feel. The 2.5" memory foam comfort layer will cradle your body and relieve pressure points so you wake up well rested. It works throughout the night to correctly align your spine, improving your posture and preventing lower back pain. Open Cell Memory Foam The manufacturing process makes a softer foam that will quickly conform to your body weight and position. Open cell construction makes for a longer lasting, more resilient foam that will not leave long-lasting body impressions. The memory foam also helps to isolate motion transfer between sleeping partners. Safe for You and the Environment The memory foam is naturally resistant to allergens and dust mites. The soft velour cover is also hypoallergenic and prevents dust mites and other allergens. This foam is CertiPUR-USA certified which means this product has been independently tested for safety of materials used, physical performance, and environmental stewardship. Careful construction guarantees no prohibited phthalates, no ozone depletes, no CFCs, no mercury, no formaldehyde, no PBDEs, and low emission (VOCs) for indoor air quality. This mattress does not contain synthetic or natural latex of any kind.25-Year Warranty We offer a 25-year warranty that protects the mattress and cover against manufacturer's defects.
