Product information
Product details
Enjoy pliable gel comfort with a firm foam-supported feel and no underlying spring unit. Best for sleepers who want a firm mattress with a gel surface response distinct from gel-infused memory foam. This 11-inch mattress pairs Technogel comfort material with cushioning foams and a foam support core. Technogel is a separate pliable gel material, not gel particles mixed into conventional memory foam. The comfort foams work with the gel above the foam support base. Available in Twin XL, Queen, King, California King, Split King, and Split California King. Check the exact pieces for split-size orders, and include the 11-inch mattress height when checking your foundation, frame, and fitted sheets.
