Product Overview


The Serenity Gel Memory Foam Mattress with CoolRest Adaptive Technology is our coolest sleeping mattress. It has a plush/medium feeling that allows you to softly float on the surface, while still feeling supported and comfortable. The 2 inch cover has two different types of CoolRest Adaptive material for maximum effectiveness. CoolRest Adaptive reacts to your body by creating a microclimate between you and the cover for individualized temperature regulation. This amazing fabric was originally developed for use in astronaut space suits. CoolRest Adaptive technology is based on micro capsules which are a phase changing material that absorb excess heat and release it to the body as needed. Combined with 3 inches of CoolRest Gel infused memory foam for comfort that's out of this world. CoolRest Gel infused memory foam was created from years of testing, and sleeps cooler than the older, heavier (5.3lb.) memory foams on the market and rebounds quicker and has the advance pressure relief and cooling properties of gel. Most memory foam requires body heat to conform; not ours- it immediately conforms providing instant comfort and pressure relief. It is made in North Carolina, packaged in Tennessee, and once opened it is ready to sleep on in 5 minutes, and it requires no time to 'air' out. It is backed by a 20-Year warranty and a 120 Day Free Return Policy. It's also certified skin-friendly by the Hohenstein Institute, and Certified by CertiPUR-US to NOT contain substances that are known to be harmful to humans such as Phthalates, Polybrominated Diphenyl Ethers (PBDEs), formaldehyde, CFCs, and others. Even the FR barrier used is non-toxic. It is inherently fire-resistant and is not treated by harmful chemicals. The foam used in the mattress is made with plant-based materials to replace the polyols, making it a more environmentally friendly product.
