Just purchased so this review is based on the chairs out of the box and assembled. These chairs will be used around our fire pit in Florida. So with time, it will be interesting to see their durability.
Back to the current time, first, they are very comfortable ergonomically. 4 adult members of my family who normally complain about any seating all gave thumbs up and one even ordered four chairs for herself. The arms are wide enough to hold your arm, cell phones a drink or two etc. Perfection. Sturdy and pretty heavy. 

Second, the gray is a win for our decor. Love it and I ended up buying two ottomans and four matching side tables.  the ottomans are surprisingly comfortable too. 

Had some minor issue with delivered pieces, sent an email to customer service who responded within 24 hours and gave first class resolution. I am very pleased.
