Query: FRUSTRATING!!!!!

Spent many hours trying to assemble this product. Some of the pieces were very warped and would not fit properly. Think we finally had it fitted together and it would pop out in another area. Very tempted to throw the thing out but I do like a challenge! So, with the help of a very large mallet mission accomplished. Piece of advice...patience is recommended! Overall, nice piece for the deck if patience is a virture otherwise, SEND BACK!
