These covers are very sturdy and we use them year round even through harsh New England winters. I will say that this is our 2nd set, as the 1st did not survive this season of dealing with 4 Nor'Easters. This was due to where the furniture and covers were located; in a place that takes direct 60+ mile an hour winds. We have since moved the furniture to an area that has better protection. We do still have the original table cover, which has always been located in a less exposed area and it has been great for 3 continual years of use. Sturdy product, but be mindful of high winds!
