Seat cushion with adjustable height in 3 stages. Easy-to-attach belt allows for securing to a chair, making it convenient to carry. - Size: Width 30 x Depth 30 x Height 3cm, 6cm, 9cm (3 stages) - Cover Material: Synthetic leather - Filling Material: Polyurethane foam The cover is water-repellent and easily wipes clean. I purchased it from the previous seller in a nearly new condition and used it for about 5 months, after which it was stored in a closet. There is some staining on the patterned seat surface. Otherwise, it is in relatively clean condition without noticeable stains or wear and tear, but please understand that this is a used item before purchasing.
