Very comfortable once put together. The assembly was a bit frustrating with less than perfect QA on the manufacturing that required me to finagle things a bit.  One pre-drilled hole in one part of each/both chairs was mis-drilled - interesting it was the same hole so their equipment isnt adjusted quite right. And then there was a badly made screw but that is why they provide two extras.  Without issues it would have taken about 30 minute per chair to assemble (the first one takes longer as you figure out what goes where, but the miscreant holes and screw added another hour.  That said, we're enjoying them now.
