Carex Toilet Seat Riser

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.
