This Broyhill Sensura 12 Cooling Gel Memory Foam Mattress is the ultimate sleep experience. Its unique construction consists of multiple layers of enhanced cooling technologies integrated into one luxurious bed. We began by laying a 6 high density support foam system as the foundation, ensuring long-lasting durability. We added a 3 layer of cooling GelFlex liquid gel infused engineered latex using a state-of-the-art process that combines cooling liquid gel with high density foam for enhanced pressure-relieving comfort and greater cooling. 1 of open cell memory foam supports our patented Edge Plus foam tray perimeter support, preventing edge sag. A 2 MicroTec gel enhanced memory foam layer provides targeted contouring support while sleeping cooler than traditional memory foam. Mattress is platform and adjustable base friendly. Foundation sold separately. When your mattress arrives feel free to enjoy the mattress immediately upon unboxing, however, the mattress may take up to 48 hours to expand to full height. The mattress may have a slight odor upon packaging removal which will dissipate in a few days as this is common of all memory foams. Certified eco-friendly manufacturing practices are used in the production of our memory foam mattresses, reducing harmful VOCs released into the atmosphere. Available in sizes Twin XL, Queen, King and California King.
