We purchased a table and chair set last August, the set was great through fall no issues at all. Then I went out to clean it this afternoon and a slat or two had extreme amounts of mold and mildew on it. Slats next to those look perfect. I would expect light black spots on a bit of it due to the wet winter, but some slats look compromised. I expect better from such an expensive item. It seems like some slats are not up to what you would expect from a teak patio set.
