    The convenience of the kit is worth it.

    Having every component shipped right to your door is worth the money. You only need to go buy the metal poles and lumber which is all explained exactly what you need in the instructions manual. If you run into any trouble there is someone always ready to take your call or chat online and help you out. Awesome service!

    From all I read and went thru this seems to by far the best choice for myself and kids coming up soon. A question tho as I didn't see it as I may of missed it. What is the height from the bottom to the top in the center?
