The large double padded seat unit has 2 phases; from 6 months, the added insert cushion can be used which offers great support and comfort to younger children. As their growth requires, this inner pad can be removed to leave the second phase seat, no less comfortable, but giving more space as an adjustable chair for children up to 3 years of age. The Polly highchair features 7 height positions, 3 recline positions and a removable tray so that baby can join in at the dinner table for family meal times.
