Delivered quickly and intact; virtually no assembly required.  These are beautifully designed and solidly constructed chairs.  I expect to have these a very long time.

Pros: No assembly required, except for plastic protectors for the feet (good idea!).  Also, they fold nicely to store, and even have a permanent heavy woven handle attached for carrying.
Cons: The only con would be that these being natural wood, they will require oiling each year, or they will grey-out.  If you like that look, that's fine too.  But oiling every year will better protect the wood.
