Cindy is demonstrating a bolted toilet seat riser with armrests, which sits under the existing toilet seat and bolts to the toilet. This may be a good option to accommodate for both improving the height of the toilet as well as having handles for upper extremity assistance when getting on and off of the toilet post knee replacement surgery. Always distribute even weight through both hands when getting up and down from the toilet.
