I just bought this. It's brand new and unused, only taken out of the box. I bought two, but I don't need one, so I'm selling it. Features: It has high resilience, and the mattress pad smoothly responds to body movements, so it doesn't interfere with natural turning over during sleep. The three-dimensionally intertwined air fibers support the body from all directions. It has excellent breathability and a structure that prevents stuffiness. Both the filling and the cover can be washed completely. The filling can be washed with a shower, and the cover can be washed in a laundry net. It can be placed directly on tatami mats or flooring, or it can be layered on top of your existing futon or bed mattress. The cover has a COOL type mesh fabric on one side and a WARM type quilted fabric on the other. I haven't removed the tape from the plastic bag, but I briefly exposed a very small part of it for the photos in pictures 4 and 5. I will ship it in the box it arrived in, as shown in the photos. Please consider it if you are interested.
