The Stokke Tripp Trapp Newborn Set turns the Tripp Trapp chair into a cozy, ergonomic infant seat from birth to about 9 kg (20 lbs). It cradles the newborn at table height with two angle-adjustable positions controlled by a one-hand trigger and optimal leg support. Safety features include a five-point safety harness with soft shoulder pads and red-green mounting indicators that turn green when the set is correctly mounted on the chair. The perforated shell promotes airflow, and the comfortable upholstery removes for machine washing. It attaches and removes with no tools and fits any Tripp Trapp chair produced after May 2003. A toy hanger and extended glider are included.
