Cooling Gel Foam from Top to Bottom

Optimum™ by Sealy Posturepedic OUTLAST® is the first mattress on the market to feature cooling gel foam from top to bottom. This mattress is designed to provide optimal temperature and comfort plus smart technology integration for deep, relaxing, restorative sleep.

OptiCool® Gel Memory Foam with OUTLAST® Gold

The Optimum® difference can be felt from the very first touch. OptiCool® Gel Memory Foam is noticeably cooler because it's the only memory foam on the market to be fused with OUTLAST® Gold material, which is 12 times more effective at removing excess heat. The result is a mattress that stays cooler while you fall asleep*, helping you to fall asleep faster and stay asleep longer. *As measured over an initial 20 minute period. Results may vary. OUTLAST® material is used in high performance outdoor gear, undergarments, and even footwear for superior temperature regulation.

OptiSense® Gel Memory Foam

OptiSense® is a layer of body-hugging, gel-infused memory foam that contours and conforms to your body's unique shape and weight, creating the feeling that your mattress was made just for you.

Gel OptiCore™

The bottom layer, our patented gel OptiCore™, provides essential deep-down support. This section, made of firmer, higher-density gel foam, provides a feeling of deep support to allow you to sleep soundly throughout the night.

Optimum Radiance Gold Radiance Gold King Cushion Firm Mattress

The first to feature cooling gel foam from top to bottom, this innovative gel memory form cushion firm mattress features OptiSense™ technology. This technology allows the mattress to conform to your body's unique shape and weight while also designed to reduce motion transfer. The exclusive 7" GEL OptiCore™ offers deep-level support combined with 2" OptiCOOL™ for the best night's sleep possible. OUTLAST® material is fused to the surface of an OptiCool® gel memory foam layer. This is the same type of material used in today's high-performance sports clothing and footwear to absorb excess body heat. This technology absorbs 12 times more heat than material not treated with this technology. This allows for the consumers to achieve the cooling comfort they desire. Experience the ultimate in cool, comfortable sleep with this premium mattress. Foundation not included.
