Nicely constructed and super-sturdy. The problem I had, which cost it a star and led to my returning it, is that even though the description says it fits tubs up to 21.25" deep, in reality it only fits tubs a couple of inches shallower than that. I was very disappointed because this is otherwise a great bench that I would have loved to have been able to use.
