I have a pair of old sling styles chaises that do/have rusted a bit from even before switching to swg, but I love the zero gravity effect and have a power washer and know how to use acid to clean up a rust spot so I still haven't replaced them 
But if you're looking for something with cushions and don't mind paying a premium, google "Polywood" furniture...it is heavyweight for longevity and wind, completely salt resistant (composite planks) and are said to last forever. Nice looking stuff. My friend has a set out by her boat and loves em. Look as good as the day she bought em.
