Got it today! This chair is great only problem I had is the washers on the sides of the seat back kept falling off and I ended up losing one inside the chair itself (Super nit-picky). With that said this build quality is stellar the chair and hardware is very beefy, the lumbar support is great and I can already feel the back pain fading as this chair forces me into a comfortable position. This thing is absolutely amazing!
FatCat332I have the similar washer issue. My problem was one of the screw won't tighten 100%. It's not too bad, but not as tighten as the other screws.
