Received these armchairs and put them together today. The process was quick, the directions are great and easy to follow. I put together 3 chairs in 1.5hrs and it would have been quicker if my 4 yr old wasn't "helping". The charcoal is just as pictured. Reviews say "it's plastic" well yes but it looks like rattan and seriously the price for the modern style... 
One of my 4 chairs did come without any hardware but wayfair is sending - inconvienient/disappointing but by no means a big deal. Their customer service was excellent.
