The Little Helpers potty training seat with ladder fits 99% of toilets and unlike a traditonal floor training potty, does not have to be emptied after use. Simply flush and toilet bowl clean up is done. This also allows your child to become familar with using a "real" toilet and the noise of a flushing toilet which makes using public restrooms much easier. Signifacantly more sanitary than others, our countoured seat is made of polystyrene that quickly pops in and out to clean easily, when needed. No padded materials to absorb urine or feces. Because there are no metal parts to rust our the Little Helpers toilet seat and ladder can also easily be cleaned in the shower, if needed. Sized for little hands our potty ladder has side rails and handles to support your child and an oversized step for stability. The footrest can raised or lowered to suit your child's needs. Easy to assemble and even folds for even easier storage. Ideal for children 2 years and up. Suitable for up to 110lbs.
