6"

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.

The height of the seat is okay for someone with knee or hip problem but the lid is very flimsy. I would not dare to sit on the lid for fear of it cracking. It feels very cheap. Wish also that it was soft close lid. They should make better lids and send a replacement to everyone who purchased it.

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

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!!

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.

After my 92-year-old father fell and fractured his arm, life changed drastically. Formerly, he was very active on his walker, continent, and raised and lowered himself with ease. Dad then started plopping down in an uncontrolled manner, oftentimes veering well off the center of the toilet seat. I would try to control his plopping by aiming his bottom toward the center of the seat, but he would just take me down with him and into the shelving next to his commode. I ordered this and one other item that changed all that. The elevated seat helped him lower himself down to the seat rather than plopping. The other item helped him center himself on the seat with his non-fractured arm. This was SO easy to install, literally under a minute. It is secure and easy to clean. The only issue is if one has a bidet installed, it can no longer be used effectively. My brother used a hot crafting knife (available at Michael's or other crafting stores) to make an opening for the stream. Problem solved! Note: The after-market bidet has helped keep him clean so much: highly recommended.
