Not 3 season or all season. Very poor quality. I purchased last spring. It collapsed a month ago. It was anchored into the lawn. I went to see if it could be salvaged, it was rusted in several areas and broken. When I was taking it apart so it could be hauled away, I was able to physically break the metal without much effort. I live in MD. We didn't get a harsh winter at all. Very upset I didn't even get a full year out of this purchase. The only reason for 2 stars is because it was very pretty once set up.
