Please understand that this is a used item. I have never had any leaks, so there are no noticeable stains, but there is some slight pilling from washing. Can be disassembled with Velcro. It has hook-and-loop fasteners, so you can peel them off and reattach them to the part of the size that is just right for adjustment. There is one hook-and-loop fastener attached vertically. Velcro contact area has some pilling. See photo. This is an area that is not visible when used, as it is attached to the cotton fastener. Cushion size: Approximately 10cm wide x 28cm long x 13cm high Will be shipped compressed. We are not responsible for wrinkles caused by compression.
