Complete and utter junk.  Maybe I got a bad set, maybe the quality control is horrible, but this chair is unable to be assembled.  The warping in the frame prevents the holes for the bolts from lining up.  You can only install the top 2 or the bottom 2 bolts for the chair side, but not all 4.  Also, the bolts are about 1/8” to 1/4” too short to start threading.  Requires the use of a 2nd person using pliers to squeeze the frame together enough to be able to start the threading of the bolt.  Nothing like this should be this difficult, which makes me think these are faulty materials.
