Well the first set that arrived was very easy to assemble - hw ever i noticed that the wood was splitting when I installed the screws. When everything was assembled I noticed the table was cracked and that each chair had at least one or two splits on the assembled parts. 
1- The replacement parts process was very easy and I was sent a completely new set to replace the old damaged set - so very happy with the process and response which was very smooth 
2- The chairs look very nice and I can't wait for spring and summer to start using outdoors
