The BabyBjörn Toilet Trainer is easy to adjust and fits firmly onto most toilet seats. Ergonomic design allows your child to sit comfortably and correctly. A FRIENDLY SEAT FOR EASY TOILET TRAINING A child is more likely to use a big-person toilet if he or she feels comfortable doing so, and the Toilet Trainer is designed to achieve this. Making kids feel safe and at ease, the trainer's soft, ergonomic shape provides a comfortable seat without any sharp angles. However, always help your child climb on and off the toilet trainer until it is safe for the child to do it on his or her own. The contoured curves also make it easy for kids to get on and off the toilet by themselves, helping them feel independent. Another key design feature of the Toilet Trainer is its opening, which is wide enough for parents to help kids wipe, but small enough to prevent a child from slipping through. FITS TOILETS OF ALL SIZES No matter how large or small the toilet is, the BabyBjörn Toilet Trainer will fit. The trainer features an adjustable dial that adapts it to toilets of all sizes. The bottom of the trainer has a soft rubber edge and adjustable wings, both of which ensure that it stays in place securely and doesn't slide under little bottoms. MINIMIZES MESSES WITH BUILT-IN SPLASH GUARD The BabyBjörn Toilet Trainer makes for hassle free cleaning for parents and caregivers. An integrated, angled splash guard helps prevent kids from making messes outside of the toilet. This splash proof feature translates to fewer accidents for kids, which in turn builds their confidence and makes them feel secure about using the full size toilet again and again. CLEANS EASILY For those family members who don't require the training seat, the Toilet Trainer has a convenient, built in handle that makes it easy to remove and replace. It is easily cleaned with hot water.
