I did alot of research before buying the wonderfold wagon. I love it and think everything is great. But I did buy it for my special needs son, hoping he would be able to use it because he has outgrown every stroller. So when we put him in we noticed he was a little long so his shoulders go past the 5 point harness so it doesn't fit him very well and he can't sit on his own. They don't have adjustable straps on the harness to move up or down like they do on the luxe. It would be nice if they made an upgraded seat for the w2 for bigger kids to be able to fit in the harness.
