I bought this based on the great reviews and plus it is just the right size for my screen porch.  There is no assembly required, just unfold and you are ready.  It has a no rust finish but I think it may be worth using some paste wax on it occasionally just to be guard against rust.  It is attractive and comfortable.  I live in a warm climate year round, but if you are in the north, this would be nothing to collapse and put away during the winter months.

Pros: Attractive, comfortable, no assembly required, collapsible.
Cons: This has a protective finish against rust but still may want to use something on the metal frame to keep it rust free.
