I've only had my swing up through 1 summer, but it was a very hot, sticky and l-o-n-g one in Florida. While it is not unusual for my porch furniture to develop mold/mildew during that time,  my swing stayed bright & shiny white and, at most times, occupied! It is truly a great, well-made item (which doesn't even "moan" when my 250 lb. husband AND I sit on it together. As well as it being a great item it was also a bargain! Love it, love it, love it!!!

Pros: Reasonably priced and the best thing on the porch!
Cons: Can't think of a one.......
