Four setups come out of one frame here: a seated activity center, a sit-to-stand push walker, a driving station with steering wheel and shifter, and a folded package 12 in thick for the closet. Three height settings of 20 in, 21 in and 22 in grow with babies 6 to 18 months, and the music box answers with sound and lights. Six non-slip pads plus a safe-distance base keep the walker planted, while noise-free wheels spare the floor below. The seat cushion detaches for washing, and the PP and metal build holds 26.5 lb and meets ASTM and CPSIA.
