Lulu has a mattress for everyone. Utilizing advanced NASA created Space Age Visco Elastic Memory Foam infused with Cool Gel, all of Lulu's mattresses are made to conform to the body's natural shape while maintaining proper spinal alignment and providing super support. The Micro Cool Gel regulates sleep temperature by effectively moving heat away from the body and dynamically cooling the bed, helping to maintain a optimal sleep temperature of 60-67 degrees F. At the core of every Lulu mattress is a base layer of Super High Density Closed Cell DuoFoam. This extremely durable base layer provides superior core support and makes every Lulu mattress comfortable for years to come. The premium materials of our Lulu beds allow them to be perfect as an adjustable bed.
