Hot carpet Size (for one tatami mat) 90 x 180cm It's a bit old, but I was using it until last season. It's thick and sturdy. The controller has some sun discoloration, but there is no damage to the carpet, and it works fine. I just took it out of the box for the photos, so the carpet has some creases, but they will disappear quickly with use. It's a 1-tatami mat size, so it's a good size for one person to lie down on or use as a kotatsu substitute. If you understand that this is a used item, would you consider it? - Model: KC-K100 - Voltage: 100V - Power consumption: 200W
