Thank you for viewing. This is a Yamazen folding shower chair. I couldn't find a model number on the main unit, but I searched using the images and it closely matches YS-1060. Please refer to the images for the size and how to use it. I will clean it as thoroughly as possible. Please understand that there may be some overlooked dirt or scratches. I plan to ship it as compactly as possible via Yamato Takkyubin (home delivery service). I will pack it immediately after purchase and take it directly to Yamato. Please purchase only if you understand that this is a used item stored at home. No cancellations or returns. Thank you for your consideration.
