Find OXO Tot high chairs, bibs and more at PishPosh Baby! OXO was founded in 1990 on the philosophy of Universal Design, which means the design of products usable by as many people as possible. For OXO, that means designing products for young and old, male and female, lefties and righties and many with special needs. The goal of making products more usable forces the company to first identify problems and inefficiencies of existing products not only in terms of comfort, but performance as well.
