I struggled to assemble the chairs myself. The holes did not line up well at all on one chair but after 3 hours of hard work I completed it.  It took force.  Not impressed with the quality really, 2 bolts were short as well and both chairs are Rocky, the same front right leg is off the ground.  It’s ok when you sit in them and feel sturdy.  You get what you pay for and these are basic cheap made.  The instructions were good however, better than other flat pack stuff I’ve had.  They look good but time will tell how they endure use.   The coffee table is easy to assemble but I’m dubious about the glass suckers so may need to buy some glue.
