We ordered the brown chair with gray cushions.  Calling it brown is a it of a stretch as the brown contains a lot of gray too.
 We have assembled many pieces of Wayfair furniture but I would recommend paying for assembly unless you have access to proper wrenches and perhaps a socket set. Doing 1/4 turns with the provided hex wrench on a 2” bolt takes forever and does a number on your thumbs. 
With that said, the assembled chair is attractive and does glide and swivel nicely. One ergonomic note - the depth of the chair seat is quite long and you might need an additional cushion behind your back to feel more comfortable.
