Getting a hip replacement soon and it hurts badly enough now to sit lower to ground as is. I'm 5'7 and my feet touch the ground just enough to reduce a LOT of pressure on the hip joint. Wife is 5'3 and it is fine for her given I have to have it installed for me but we both need to use the master bath. So it should be fine for most adult heights. The bolts were the same width as those that came with the Kohler toilet seat, and the holes in the riser were drilled at the right locations. The bolts were plenty long enough to easily secure both the toilet seat and riser to the commode. There is a metal washer that goes under the bolt head at the top, that fits well into the toilet seat hinges, and the plastic washer that goes underneath just before the wingnut also does the trick. Bottom line is everything installed as adverstised and works perfecty. It is also very secure. The hinge on the riser is great to allow for cleaning.Helpful hints: You may need pliers to hold the wingnuts from turning as you tighten the screws to maximize the secure fit. I also recommend using the washers that come with it. If you use all metal washers and don't use the plastic washer on the bottom, you will not be able to get it as tight as you want, and also risk cracking the commode as you try.This product is highly recommended.
