4"

I bought this because my mother has MS and mobility issues. We raised her motorized scooter seat to make it easier for her to get in and out of bed but that left the toilet seat to low. We had a 4 inch riser before this one that we got at a local drugstore. This one is truly taller and exactly what we needed. The plastic is very sturdy and easy to clean. I was skeptical when I took it out of the packaging but it really works. It cannot just sit on the toilet, you have to use the clamps but the clamps are clamping! Our shorter riser had a tendency to slide no matter how much we clamped it. This seat is not going anywhere. It's been very helpful in the few weeks we've had it and it serves us purpose very well for my house. Update: We've had this for several months now and it works great. Even the lid is still going strong and is vast and dignified improvementover every other riser we've ever had that didn't come with a lid. I am able to sit on it without breaking it. And even my kids who are destroyers of everything have not found a way to destroy this. I am donating one to a friend who is having surgery and I feel very confident saying this is what they need!

This toilet seat riser saved my knees (both need replacing and go out periodically) and helped so much after tailbone surgery the other day. It hurts to squat even the smallest amount. With this on my toilet, I can sit right down and stand back up with very little pain at all.

** UPDATE on June 24, 2025 ** After seeing my review, the seller reached out to me which I thought was incredibly considerate of them to do. They were patient, kind, and understanding. You can tell they care about their customers! They worked with me and provided the perfect solution to the issue by way of giving me a complete refund and suggesting I repurchase the seat through Amazon to ensure a very prompt delivery. I'm very satisfied with the seller and appreciate their reaching out to resolve the issue :) ** Original Review ** I bought this on behalf of an older friend of mine. The fit is good, and it even looks fairly nice in appearance overall. But the lid ... it has flimsy plastic hinges that broke off. The cover is gently opened and closed, it should not have broken like it did. This means the top has to be 'leaned' or 'removed' and placed elsewhere when the toilet is in use. There isn't even a way to repair or jimmy rig the cover to reattach it. We are past the 30 day return window unfortunately.

My very tall husband has bad knees and most toilets are too low for him to easily get up and down. When he learned he was going to require heart surgery, we knew that grab bars weren't going to be an option so I shopped for toilet seat risers. This one was perfect. First, I don't have to remove the existing toilet seat and lid. This one sits down on my oval shaped toilet and clamps with two screws on the side. At first I thought it wasn't going to stay put and be unstable but when I loosened the screws on the sides just a little, it became very stable. This seat is taller than most of the ones I've seen advertised so this was a real plus for my husband. I put it on a newer, taller toilet and had to add a stool for the short people (me) in the house. If you have standard toilets, this will be perfect to give the average person a little height so they can easily get up and down. It's easy to clean, has it's own lid and doesn't look too bad.

The lid is very flimsy. It broke on the latch even before we got it installed. However I do like the way it fits on the toilet. It totally covers the rim so crud doesn't get under it, like my old one that just sat on top. And it goes on and off easily so I can take it off and clean under it periodically. For that reason I didn't return it as soon as we got it. But buyer beware that the lid is flimsy is an understatement.

NO, WOULD NOT FIT ON THE TOILET KEPT COMING OFF. THE LOCKING HATCH WOULD NOT HOLD IN PLACE. DIDN'T REALIZED HAD GONE PAST THE RETURN DATE. STUCK WITH IT. NOT MADE VERY WELL. VERY DISSATIFIED!!

A fine product with easy installation. Good value and fulfills its promises.

I had total hip replacement, and this seat really helped me the first month
