It fits well on the toilet. There’s a small gap on the side of my toilet, but it stays firmly in place with the clamps. The problem is that it’s a little short, so it leaves a gap at the back and reduces the usable space on the toilet. Nevertheless, it’s very helpful for an elderly person who has difficulty sitting down and standing up

Very good construction and the clamps keep the seat stable. It is easily removed for cleaning or if the toilet needs to be used by someone who does not need it. The model with the lid is clearly more convenient as the toilet lid will not be able to close.

For perfect stability, I glued it to the toilet bowl with silicone because my elderly mother was shaking it.

Very easy to install, ideal seat, very convenient lid (recommended) but you can't really say the screws "tighten," they just "stabilize." If you pull it all together, you can easily take it off with your hands. Of course, it doesn't slip from the bowl, so... ok

I got it for my mother who had knee replacement surgery and for the first few months she couldn't bend her leg enough to sit at the original low height of the toilet. It is very easy to install and stable. It does its job.

It is very easy to install. It raises the toilet bowl quite a bit. For people with problems and the elderly, it is just fine. For people without problems, it is unnecessary! I hope it lasts over time!
