The baby set consists of high back and rail supports. Your child can start using Tripp Trapp® with the Tripp Trapp® Baby Set™ when they are able to sit up unaided, usually around the age of 6-9 months. It can be used until your child is approximately 3 years, providing protected seating for your child. The baby set is available in the same colour range as the Tripp Trapp® chair.
