The NOVA Medical Products Toilet Seat Elevator arrived quickly and was packaged in a nice colorful box. I ordered the white elongated rise. It came with easy to follow instructions, long bolts, washers, and wing nuts. Installation was very easy and self explanatory. The riser lifted the toilet seat to just the right height. My husband had back surgery recently and was struggle to use the over the toilet walker style raise toilet seat. The walker style seat was uncomfortable and the older round style. I searched and searched and searched and was unable to find anything like this riser in stores, not to mention no one actually carries the elongated version of any style. After many stores, I finally ordered this seat via Prime and it arrived right away! The seat was much more comfortable and easier to use than the walker style seat. This riser simply goes under your toilet seat to raise it up and installs all parts together with the long screws. It’s made of a hard plastic non porous surface and was very easy to clean. It bolted together tightly and did not move or shift during use. This was perfect for his after surgery recovery and a great price compared to the horrible things carried in stores. I did pay full price for this item and would gladly do so again! Was just what we needed! Thank you NOVA Medical for making such a great and helpful product! This toilet seat riser was a huge life saver!
