Purchased in November 2024 at the bedding section of a department store. It is a Nishikawa Healthyon, single size. Used only a few times during the winter season. I purchased another one last year, so it has been stored at home until now. The condition is very clean. There are no stains. I think it's almost unused, so I have indicated the product condition as "Like New." This is just my personal opinion. Please check the images and consider purchasing. Please understand that this is a used item. Operation has been confirmed. The warranty is only shown in the photos. The warranty period is one year and has expired. Please understand. A dedicated cover is included. It has been home-cleaned. Please let me know if you don't need it. Size: 100 x 195 Single Color: Gray Retail Price: ¥242,000 (tax included) This is a mattress that supports your health. It comes with a storage bag. - Brand: nishikawa - Product Name: Healthyon - Accessories: Instruction manual Thank you for viewing.
