Excellent condition TEMPUR wheelchair cushion, 40x40x5cm. This item was purchased new and used for a short period for guests. There are no issues such as sagging or stains. (^_^) Although it is a wheelchair size, it fit perfectly on the size of a wooden Tendo bentwood chair and I was using it. I am selling it because I purchased another one for a room remodel. It is in very clean condition. It has been stored in a closet. ■ Size Approximately Width 40 x Depth 40 x Thickness 5cm About this product ・Size: Approximately Width 40 x Depth 40 x Thickness 5cm ・Color: Navy ・Supports comfortable seating even for long periods.
