The premise behind this table is, "Why have a middle on a coffee table when the drinks are placed on the edge? Might as well be a trampoline." Couldn't have said it better myself.
i don't know... maybe it's for the trampoline diehards who don't have anywhere to store their little trampolines and want to camouflage it as a piece of semi-useful furniture when they are not jumping on it... If not, it sure throws the standard admonishment of "don't jump on the furniture" out the window.
