This is a fitted sheet for a futon, made with Smart Heat, a moisture-absorbing and heat-generating material with 100% natural cotton pile that touches the skin. The cotton Smart Heat fabric on the skin side has a 100% cotton pile, and the ground part converts sweat and water vapor from the body into heat, providing warmth that is +2.3°C warmer than regular fabrics with a similar pile length. The back of the sheet has an all-around elastic band for a neat fit with less bunching. It is also resistant to slipping and easy to put on and take off. It can be easily washed in a washing machine using a laundry net. This cotton Smart Heat sheet is made with natural materials so that those who are sensitive to synthetic fibers can use it with peace of mind. * All-around elastic band * Machine washable (using a laundry net) Color: Soft Brown Quality: 100% Cotton Size: Fitted Double Width 145x215cm
