Thank you for viewing. This is a piano footrest. Approximately 36cm (length) x 35.5cm (width) Height is adjustable from approximately 14cm to 21cm. As shown in the photos, there are some scratches on the main body, but I believe it can be used without any problems. My child has grown and no longer needs it, so I would like to give it to someone who can use it. I am looking forward to your purchase if you understand that this is a used item. Thank you very much.
