"Q-MAX Contact Cooling Value: 0.552W/cm2" (※The feeling of coolness when touching an object. The higher the value, the colder.) Cooling value up! Cool to the touch, every time. Completely covers futons and mattresses. ◆POINT.01: Achieves approximately 2.8 times the standard contact cooling! Cool and refreshing, you'll want to touch it in the hot summer. Uses "contact cooling" fabric made of polyethylene, which has higher thermal conductivity than nylon. Furthermore, the weight per unit area is increased, increasing the contact area of the fabric, resulting in a cooler feel. [What is Q-MAX: It is a numerical value that quantifies the amount of heat transfer at the moment of touching the fabric, and is an indicator of the coolness when touching an object. Contact cooling materials are those with a Q-MAX of 0.2W/cm2 or more, and the higher the value, the colder it is.] ◆POINT.02: All-around elastic prevents bunching! All-around elastic on the back to completely cover. Can be used for futons and mattresses up to approximately 25cm thick! Easy to set up, just cover it, and it looks neat. ◆POINT.03: Washable at home! Always clean and comfortable. You can easily wash it even if you are concerned about sweat and dirt, and you can always use it clean. Because it is bedding that is easily affected by night sweats, "antibacterial and deodorizing treatment" is used. It suppresses the growth of bacteria that cause unpleasant odors. ●Product Size (cm) Single: Width approx. 100 x Depth approx. 200 x Height approx. 30 ●Weight Single: Approx. 880g ●Material Nylon 64%, Polyethylene 30%, Polyurethane 6% Retail Price (tax included) ¥4,398
