We ordered two chairs and the positives are the sliding head cushion, the black tubular construction and fabric is good and armrests are comfortable. The chairs were already assembled and they are very easy to open and close. 
Areas for improvement are the locking mechanisms are flimsy and one chair was missing the washer impacting the safety of that chair. The design itself has too much forward rock ability and not enough backward. When you rock back it abruptly stops too soon. Overall the are nice and we are enjoying right now with a glass of wine! Thank you Wayfair!
