Futons are special because they have flat mattresses that bend into upright couches, which allow them to serve a dual purpose in the bedroom or living area. Futons originated in Japan but are now embraced in the West. Futons typically consist of two pieces: a frame and a mattress. The best frames are constructed from wood, metal or a combination of both. The frame supports the mattress, which is laid on top or connected to the frame on certain models. At night, lay the frame flat so the mattress is horizontal and, during the day, fold the frame upright so the mattress bends in the middle, creating a loveseat. Most futon mattresses come in full or queen bed sizes. Choose a mattress with a firm foam or polyester filling, or search for one filled with cotton or wool for a more natural option. Enclose the mattress in a futon cover to protect against spills, bodily fluids and insects. Opt for a hypoallergenic cover if you're an allergy sufferer. Some futon mattresses are made from high-end materials like leather or suede and are not meant to be covered. Other mattresses sport a pillow-top for added comfort.
