I purchased this for my 17m old for Christmas. Even though he's not quite jumping yet, he loves to get on the trampoline, hold onto the bar, and bounce up and down! It easily converts into the ball pit. If you need to store it, you remove the bag which is already storing the balls, and the trampoline folds so easily. It's very compact and easy to use. The only reason I gave 4 stars is because 100 balls is not nearly as much as you would think. In the pictures, they make it look like it will fill the entire bottom of the play area, but it doesn't even make one complete layer. 100 balls ends up being somewhat underwhelming. Otherwise, great product! Well worth it!
