Thank you for viewing. I purchased this for a family member who has difficulty sitting and standing. However, my toilet is a Japanese-style toilet, so I was unable to install it, and I am now selling it. It has not been assembled, nor has it been installed in a toilet. I have confirmed that all parts are present. Although it is unused, it has been stored at home for about two months, so I would appreciate it if someone who understands this would purchase it. Thank you.
