The instructions to put this together are terrible!  ***** Make sure all the push in knobs are facing inward when putting the bottom frame together.  If you don't  do this the holes for screws do not line up.  Also, look carefully at the netting directions and make sure to slip the bottom part over the bottom pole before putting the top pole on***  The hardware on this is cheap and we will likely have to get new hardware after the season because it was all stripping.  The wrench and Allen wrench do not work for putting the upright poles on.  You need better tools.  The net is also too small.  The zipper does not shut all the way once you get the net totally installed.  We just put it up today.  Kids love jumping on it.  That part is good.
