I purchased 8 of these chairs in white, and I love love love them!  The off-white upholstery and black legs match my table perfectly.  Granted, my husband is a mechanical engineer, but he had no difficulty assembling them using an electric hex drill, which was easier than using the provided Allen wrench.  He recommends beginning with the back leg assembly, starting the 3 middle screws, followed by the 2 screws in each corner, leaving them all loose.  Then tighten the 7 back screws, beginning with the 3 in the middle followed by the 2 in each corner.  Install the front legs last, leaving the screws snug but not tight.  Then have someone sit in the chair, and go back and forth, tightening the screws until the legs are level and solid.
