We've only been using the chairs for a couple of weeks but so far they're very comfortable.  I love the style and color.  They weren't difficult to put together but it did take a while with only one person.  The only draw back would be that the cushions don't attach to the chair (which I think could have been solved with some velcro straps on at least the front end).  It's not a huge deal as we can easily store them in the garage when not in use but with the amount of wind we get, it felt like it was worth a star to us.
