Also includes back rest, rail & extended gliders to prevent your child from crawling out. | LEARN TO SIT - While your little one is learning to sit, the Tripp Trapp Baby Set offers comfortable side + back support.

When your child can climb in/out of the chair, remove the Tripp Trapp Baby Set & readjust the chair accordingly. | DESIGN WITH A PURPOSE - Tripp Trapp was designed by Peter Opsvik in 1972. Inspired by his young son Tor, who had grown out of his high chair but was still too small for an adult chair, Peter aimed to seat all ages at the same table comfortably.
