The chairs are sturdy and comfortable. The seat and back are put together already, so assembly was easy and fast, with clear instructions. The seat is 20" deep and 20" wide. They are folding, but not adjustable in terms of the back incline. I love the slate color I bought. The only reason I am not giving it 5 stars is the folding function. 1) No matter how much you tighten the bolts, there is some movement in the chair. Hopefully this won't cause issues over time, 2) To fold the chair for storage, you should loosen some of the bolts to prevent wear-and-tear, so the feature is really only useful for out-of-season storage. The chairs have been out in Colorado fall weather only couple of weeks, so I'll try to update this review at the end of the season.
