1. NOTE: Please allow up to 72 hours for the mattress to fully expand and for any potential odor to dissipate.
2. ADAPTIVE FOAM: Constructed with freshly poured T&N Adaptive foam, this mattress provides a bouncy yet supportive feel perfect for all sleeping positions. Our foam allows us to compress our mattress to fit into a small box and shipped quickly.
3. HIGH QUALITY: Our high-grade foam is more advanced than outdated materials such as latex and memory foam which cause you to "sink in and feel stuck" and "sleep hot." The T&N Adaptive foam sleeps cool, is just the right mix of "not too soft, and not too hard", and offers great pressure relief and "localized bounce" so you won't disturb your sleeping partner.
4. NO RISK: Mattress has a full refund guarantee with a 100 Night Sleep Trial plus an honest, 10-year warranty you can actually use (no gimmicks); Over 95% of our customers keep their mattress and refer it to others
