Install the seat with handles and sit, or stand on the step board only. Both can be used. Everything in the photos is included. There are no tools, instruction manuals, or outer box. Please see the photos for the condition. The seat will be shipped detached. Thank you. There are no noticeable scratches or stains, and I think it's clean.
