The solid wooden body and low centre of gravity give the Radio Flyer Classic Walker Wagon maximum stability. The wheels are heavy duty moulded with grip tread and the moulded front bumper helps to protect the furniture! The push handle is made from chrome and the removable stand-up sides are made from wood. The 'resist' push feature really helps beginner toddlers to get the hang of it without the Wagon running away with them. The Classic Walker Wagon is so good that it's been one of Radio Flyer's best sellers for over 25 years, and the design just keeps getting better. Size: 22" (L) x 12" (W) x 15" (H) Recommended age range from 1 to 4 years.
