Memory foam was invented for spaceships—and then we took this foam beyond outer space with a gel cooling upgrade. These foam-infused gel capsules draw heat away from your body, so you can finally enjoy both perfect body contouring and perfect cooling. 

Each Tranquility Sleep System mattress is CertiPUR-US certified.
