Thank you for viewing. This is a Yamazen folding shower chair. I couldn't find the model number on the main unit, but I searched using the images and it almost perfectly matches YS-1060, so 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. Shipping will be as compact as possible via courier service. Please only purchase if you understand that this is a used item stored at home. No cancellations or returns. Thank you for your consideration.
