Eight activities across the panels keep a baby occupied whether they are sitting to play or standing to walk. The handle sets to three positions, so children of different heights can push it with a comfortable upright posture that supports healthy leg development. Rubber rings on the wheels give skid resistance on hardwood and tile. MDF and plywood construction keeps the 11.5" x 13.5" frame stable at just 4 lbs, light enough for a toddler to steer alone. Suits ages 1 and up.
