Used it the other day for my husband who has a broken foot, but no cast. Worked great and was able to help him shower.
One thing he did which scared me was he went to stand up to get out of the shower and leaned on one handle only, which tipped the chair to that side. I was there to put pressure on the other side, so it would not tip over. It needs equal pressure on both handles to keep it flat on the ground.
