We bought this in July and have it at our beach rental. We came back in September and it had mildew all over it. Scrubbed it down. Looked fine. Came back for Thanksgiving and it’s BLACK. We have it in a sunroom so it’s not the same as being completely under air but we did not expect to only get a couple months out of it. If we could return it - we would love to.  I wish I would have thought to take pics before scrubbing it this time. This is a photo from after cleaning it.
