This children's slide shaped like a bear / elephant (animal shapes might vary from slide to slide) would appeal to kids. Not only is the slide easy to assemble but it can also be fitted to accomodate older kids. Two different heights are available with the result that kids aged 2-6, all can make use of this slide. 

Quality wise this slide is highly recommeded. Sturdy plastic with plastic bolts & screws with no hard edges/sharp points anywhere ensure that children won't hurt themselves while playing on the slide.

As a bonus a soft basketball and a basketball loop also come with the slide. Other children waiting in line for their turn at the slide can try a shot at the basket while they wait.
