Four activity modes share one 29 x 24 x 20 in unfolding frame in this foldable activity push walker, allowing babies to sit, walk, push and play under a rolling toy car body. Three adjustable height positions from 20-in to 22-in help the walker match your baby’s growth, while the adjustable rear wheels let you set resistance for different walking strengths. A cushioned polyester sponge seat supports up to 25 lbs and removes for washing. Five non-slip stair pads and a safety bumper add stability as your baby moves.
