My two little twin 4 year-old nephews have been the happiest little boys ever since I purchased the Upper Bounce Kid-Friendly Trampoline.  I decided that I could not wait till Christmas to give it to them, so they got Christmas in August.  It was a good decision.  Living in New York state means that snow will arrive soon.  Their father easily put it up in their backyard and immediately Cam and Owen were bouncing till their hearts content.  Best little beginner trampoline.  Great quality, easy to errect and looks good.  Can be used in doors or out.  Can't wait to purchase a larger one when they are a little older.  Thank you Wayfair for making two little toddlers very happy!
