MOBB Home Health Care 4 1/2" Foldable Hinged Raised Toilet Seat with Safety Rail (Elongated)

It works well for my husband. I like that your regular toilet seat goes on top and you can lift this seat extension as well. We didn't use the arms even though we put them on at first. They are simple to attach and take off and are adjustable. They hindered my husband as he has movement problems with his Parkinson's so we removed them. I highly recommend this raised toilet seat. It's very well made.
