Question: does this fit enlongated toilets?
Document: I have a very low toilet and needed a riser after knee surgery. This didn't fit our seat- had to buy a new one- and it looks weird because our toilet isn't white, but the height is so much more comfortable that I don't plan on removing it until I can replace the whole toilet with a higher one. I have a small bathroom. The new higher toilets are mostly elongated and too large, but this seat fits the older round models and is easy to keep clean.
This is an excellent toilet seat riser. You use your own seat and lid with it and the lid will close. The seat and the riser both lift up for easy cleaning. It is very sturdy and easy to clean. This makes a perfect height for the low toilets. It's a little high when used on the 'comfort seat' height toilets.
Elevation is fine, cleaning is easy, but less cleaning would be required if it fit the bowl better.
This item was easy to install. We like the hinged seat since it makes it easier to get to the bowl to clean.Four stars because it doesn't quite fit. Yes, i'd recommend it.
I ordered this item and it would not fit. I called the store, gave them the order number and was told to return it that there would be an 18% restocking fee. I paid $14.85 to return it then found out that item was not returnable because of Florida state laws. Why wasn't I told this before I spent another $15?
The hitch is that it doesn't fit my toilet. Toilet's a standard size round, not new but not ancient by any means, but this product is an inch shy of fitting to the outside edge of the toilet bowl, which of course means it overhangs the inside of the toilet bowl by an inch as well, and only has about half an inch of the product actually rests on the top of the toilet bowl. My existing toilet seat doesn't fit the riser seat, either.
it is just what we needed  w0rks well for us
Works well. Does what I wanted it to do. Raises the seat up so my husband can get down and up easier. Little hard to clean around, but I wanted something more permenant. By using my own toilet seat, makes it feel less like a "handicapped toilet".
We've had ours for nearly six months and has been a relief from the pain of raising off of a low toilet. Cleans easily and very solid.
We were not disappointed in the performance of this elevated toilet seat as an add-on to our existing toilet. The normal seat and cover installed on top of the elevated seat and all three hinged parts folded up and stayed up (for cleaning and male urination) just as described.We would recommend this product to anyone who needs an elevated toilet seat add-on.
Answer: yes
