Purchased in the fall of 2025 and used a few times → stored unused for about a year, kept outside the bathroom. I threw away the outer box and instructions, but I believe it's a shower chair from Iris Ohyama. The seat and backrest are made of plastic. Height is not adjustable. Overall height: 80cm Height from floor to seat: 46cm Length 44cm x Width 42cm There are no noticeable scratches or stains, but please refrain from purchasing if you are concerned, as it is a personal inspection and has been stored at home. It will be disassembled and shipped in a waterproof bag → bubble wrap → cardboard box. Feel free to comment if you have any questions!
