Futon Fabric Japanese futon mattress fabric uses cotton knit material with a medium filling and microfiber fillings to provide good support on the mattress for a comfortable sleep. Versatile Mattress This floor mattress is an ideal choice for floor beds in guest rooms, hotels, dormitories, hospitals, and travel, as well as for hosting guests. It can be used as a floor mattress, camping mat, bedroom futon, living room futon, lounger, sleeping mat, guest bed, or futon, and can also serve as a children's play mat or floor pillow. Breathability The breathable material and advanced ventilation system help keep the double mattress dry during sleep, reducing heat buildup in hot weather so you are less likely to toss and turn. Ergonomics It conforms to the curves of the body and supports cervical spine alignment. It can help improve sleep quality and alleviate back stiffness; the futon mattress automatically adjusts to your body weight to distribute pressure evenly.
