Not for the cowardly; This is the only chair on the market that actually works! And it works very, very well, including Full Toilet Training. Folds and stores in seconds, easy to carry, travels well.
(Please note that although the Toilet Chair may look simple (good engineering often does!), a lot of meticulous design, trial and error, crazy experiments, and sleepless nights went into this product. It is very difficult to make. It takes patience and many hours to get the bowl, tubes, gag, finish, and everything else right. Hence the premium price)
