As a professional organizer, I use this particular rolling storage system in nearly every garage of clients who have children. It has impressive storage capacity while also being sturdy. It rolls nicely as well if you'd like to wheel it out to the driveway for the kids to play. It holds sidewalk chalk, bubbles, sports balls, skateboards, lacrosse sticks, jump ropes, shoes, helmets...you name it!
I could also see this in a home gym to hold a couple of light kettlebells and weights, yoga mats, medicine balls, and the like.
