It's a fairly-well designed toilet seat riser that installs under your existing seat, raising it by three inches. The mounting slots allow it to be adjusted forward or back slightly, to account for variances in the bowl size (something we're seeing more and more, as toilet manufacturers seem to increasingly stray from conventional dimensions - Kohler, I'm looking right at you). It's quite sturdy, and the 300-series stainless steel bolts and fixtures hold things together nicely, as long as you tighten them down. The butterfly nuts work most of the time, but on a few occasions we had to switch to a hex nut & steel washer due to the wings being obstructed (again, on a bizarre Kohler "designer" model toilet). On the rare occasion that the underside of the toilet, around the mounting holes, has an irregular surface - a large rubber washer with a steel fender washer often does the trick. We usually add 3/8" a steel washer, anyways, and occasionally a locking washer. The foam-rubber padding, installed on four points under the riser, also help prevent it from slipping around the surface of the commode. As other reviewers have pointed out - in some cases the inner rim of the toilet is lined up with the riser in a particular way where liquid may run down the side of the riser, and between the porcelain rim of the toilet and the riser. It doesn't happen with with every toilet (1 out of 3 in my experience), but it's been an issue with several popular brand-name toilets we've installed these on. We recommend to our clients to loosen the butterfly nuts, but don't remove them. This provides an inch-or-so gap where one can use a spray washer or steamer to clean and sanitize in between the riser and toilet, without having to remove everything. We've attempted to use adhesive rubber as a gasket seal, but it didn't help very much - liquid eventually did seep in, as the riser would still move around slightly during use. Caulking worked to some extent, but made it difficult to remove the riser if needed, if the caulking didn't fail by then (the riser still moves around during use, and contracts and expands at different rates from the toilet). Despite this problem, the Carex B306-00 Elongated riser is one of the better risers on the market, especially at this price. We've installed much-more expensive risers, and even those still had difficulty with liquid settling between the porcelain and the riser. Hinged riser designs alleviate this problem, but come with their own host of problems (installation difficulties, too much lateral movement, and breakage the most common). This riser is also far more sturdy and safe than risers that clip on top of the seat. As such, we most-often recommend this item to our physically challenged clients, who require additional height on their toilets. Despite it's problem with liquid sometimes seeping under it, it's a good quality unit that's sturdy, has very secure hookup parts, and is well-priced.

In the end it worked, but what should have been a 5-minute installation turned out to be about an hour. The toilet seat assembles onto the riser and is held in place by two long bolts that replace the current toilet seat bolts. The first difficulty I encountered is that the bolt heads for the elongated bolts were so big that I couldn't close the caps that hide the bolts on the toilet seat. 10 minutes with a grinder and I was able to "modify" the bolts accordingly (see attached photo of before and after bolt heads). Next, the area at the back of the riser that the bolts go through is displaced about 10mm upward rather than lying flush on the toilet surface. This means that if you tighten the bolts, the front lifts up from the toilet. Why this was done, God only knows. I used the washers from the original installation hardware in a stack with some garden hose gaskets to create a shim stack to bridge this gap (see the photo, the gaskets compress some, so I guess the gap is 9-10mm). As a final touch, I added some double-sided tape between toilet and the riser at the front edge of the riser (you can seem some in the picture above, but in the final installation, the two pieces were replaced by a single piece about 2" wide at the front). It's rock solid now. It's pretty clear to me that whoever designed this has never installed one. Not a chance. I'm an engineer with over 30 years experience and this design could be improved significantly for little effort. It's kinda mind-boggling. Oh well, it's for my 93 year old mother who is coming over for Thanksgiving. I think it should help her immensely getting up and down. It's just a shame something should have been so simple was unnecessarily complicated.

I don't write reviews; certainly not for a toilet seat. This one is genuinely worth the hype. Fits the oval seat, screws into place (which means it can't possibly slide off sideways at 2 am) and allows you to still use the toilet seat as, well, a flat seat. Admittedly, removal of the old seat and install rivals that of a normal toilet seat, only moreso (fifteen minutes, two screwdrivers, few curse words) but is not difficult; the end result is -well- worth the cost of admission. For a 200lb person it's working well (I can't speak for heavier) to the point I ordered a second.

Little work to get it on correctly but once you do it's very safe and the family member that needs it finds it very stable and safe for someone that has a compromised standing ability. Just make sure you attach it very tight

I now own 2. The first one I purchased (for our upstairs bathroom) about a month go. I installed it without any issues. I just bought this 2nd one for our downstairs bathroom. I did though encounter a minor problem. When I tightened the rear mounting bolts, the front of the riser raised up about 1/2". To easily correct the problem, I shimmed the back of the riser with garden hose rubber washers (2) and passed the mounting bolts through the washers. When the bolts were tightened the front of the riser remained flush. Other than that, great product! I gave 4 stars only because of the installation issue, which could very well be a problem for some.

Product was easy to install, very solid and easy to clean. I would recommend this for anyone having knee surgery.

the holes on the toilet seat do not align with Australian toilet standards

A much better seat elelvator than most on the market

A game changer gives a good 5 inches to sore or replaced knees. You do have to remove your other toilet seat

Good height
