I bought 2 of these chairs on Tomato Red.  Took me about an hour to put them both together.  After re-tightening all the screws and bolts, I sat in them to test them out.  I felt like I was siting in a very breakable chair, not ther best construction, kinda cheap.  And they are very light.  I can easily lift them with 1 hand.  I'll be putting 2 coats of polyurathane on them to preserve them from the elements, but I don't expect them to last all that long.  Still, at $70.00 you can't expect qaulity lumber and construction.  So if you are looking to go on the cheap with an adirondack chair you could do worse.  Just don't have your 250 pound guest sit in them.
