Balance Mattress with Reduced Sagging - Futon Original Price: ¥7,678 I am selling this because it didn't fit in my storage space. It has been used only 3 times, so it's practically new. It will be shipped in its original futon bag. Regarding the price, the shipping cost is around ¥2,500, so I have set the price accordingly.
