We have the 9" one. Bought it on Amazon only about $25. Works well for the entire family (2 jpouchers and even the non - jpouchers). I suppose you can try a 9" step stool if you have one. But your feet should be positioned slightly out to the side not directly in front of you. You can Google videos of Squatty Potty. Some people say simply leaning back or at different angle helps them go more easily. Can't really think of any cons.
