Japanese floor beds, or tatami mats, were originally used to cover the lower half of traditional Japanese homes. Their unique look and feel has made them increasingly popular in the west, where they are frequently used in modern homes as a stylish choice of flooring. Tatami mats are made of tightly woven rush, a material that has been used for flooring in Japan for centuries. Their pliant nature makes them particularly comfortable to sleep on, and they can be easily made to fit any room in your home using simple joinery techniques.
