Four activity modes share one foldable 29 x 24 x 20 in frame, allowing your baby to sit in the seat, stand and push, or play on the floor under the rolling toy car mode. The walker offers 3 height settings from 20 to 22 in so it can better match babies from 6 to 18 months, while adjustable rear wheels let you adapt rolling resistance to their leg strength. A removable, cushioned seat keeps your child comfortable and is easy to wash. Built-in music, lights, steering wheel, shifter and toy mirrors keep little ones engaged within the 25-lb capacity.
