We started to try to put it together about 20 minutes ago. Seems straightforward enough, but despite both our big brains and smallish muscles, we cannot get the sides to snap in. Also, a part of the plastic had already broken off--in transit, I'm guessing, or a prior buyer who returned it because s/he coudn't get the sides to snap in???? We'd be willing to ignore that broken bit if we could get the sides on.
