We bought the exact same product in the spring of 2012 and it performed great.  Washed the covers which are removable a year ago.  Thought that leaving them out through endless rain, snow and hot summer days they would suffer but they didn't.  The shape fits so well in our location that we thought that we should replace while still available. Which we did.  Sold the original set for $300 and could have sold many more on Craig's list.  Great product.
