The Radio Flyer Walker Wagon was purchased for my son on his first birthday.  It was received with easy to read assembly instructions.  After 20 minutes, the wagon was ready for use.  The quality of this wagon was sturdy.  Having a boy, things become destroyed easily but not this walker.  He loves to push it along while taking his toys for a ride.  His sister, who is 3 years old, likes to let him crawl inside and push him around.  The children play with this together for hours.  The side panels come out to allow for easy access for kids and preventing any injuries.  I would recommend this...
