The Squatty Potty Flip Bamboo Toilet Stool helps align the colon for better elimination. To simulate a squatting position, all you have to do is take a seat, put your feet on the toilet stool, and get comfortable. Prefer the 7” height, but someone else in the home requires the 9” height? This Squatty Potty adjusts between both heights with just a flip. Its clever design requires very little effort to accommodate anyone's squatting needs. So simple...yet so smart.
