These are VERY heavy so be sure to have two people to lift the box. The instructions were pictures only using numbersletters for each part which was difficult.  I bought two of these one for each side of our fireplace. I laid out all the parts by order they would used and that helped.  The first one took me about 40 min to assemble.  The second I was much faster about 25 min.  Make sure not to tighten screws completely until the pieces are all in.  This helps line up the holes correctly. Then it tightens up at the end and is very sturdy!  Handy tip A power drill with the right bit was so helpful! They turned out very nice and I have had many compliments on them!
