My son broke his leg playing soccer, so I used this for 2-3 months. I'm selling it at a low price, so I hope elderly people, those in介護, or those who have suffered fractures can use it. It's lightweight and foldable, so it doesn't take up much space. The seat height is adjustable in 3 stages. Please check the Shimamura Sangyo website or Amazon for details. There are no noticeable scratches, but there is some dirt and a feeling of use. I will ship it from Gifu Prefecture, cash on delivery (着払い), so thank you.
