The Drive Medical toilet seat riser with handles is designed to aid people in getting up and sitting down. This locking device comes with a larger, heavy-duty "worm screw" and locking plate for a safe, secure fit. Our elevated toilet seat adds an extra 5 inch of height to the toilet and includes padded armrests that can be easily adjusted or removed. It fits on most elongated and standard toilets and installs without tools. Backed by a limited lifetime warranty from Drive Medical, a leading brand of bathroom safety products, mobility aids, and other medical goods for more than 20 years, you can purchase with confidence.
