Query: Too high for standard toilet

I bought this for recovery after a double hip replacement for a 5' 10" tall man. It was way too high on a standard height toilet. His legs went numb while sitting on it because his feet did not sit flat on the floor. It may work for older toilets that are very low, but did not work for us. I wish I had bought a 3 inch riser, but the reviews for this one seemed like it would work great. I wish I had measured the toilet we have from the floor first to get the correct lift.
