I just put this set together and wanted to let folks know, it was one of the easiest assembly jobs I have ever had. It took more time to unpack and get all the plastic wrapping off the chairs than it did to put it together. The chairs ARE stackable. The table glass is tempered. For the gray color version the glass is tinted orange and matches the coffee table I already had on my porch. The set is extremely high quality. The chairs came intact. Only the table legs and shelf underneath had t o be assembled. The trick is, as others have said, not to tighten the screws until you have all the screws in and loosely tightened. It also pays to lose the Allen wrench and use your own socket wrench or socket driver. Two people arent needed. Im a woman in my 50s and managed just fine.
