The day after I placed my order,  I saw them in white on the patio at a local restaurant.  The waitress said they had been used on the patio for over a year and as far as she knew none of them had ever broken.  Upon close inspection they did have some marks at the bottom of some of the legs but considering the heavy use I was impressed.  I was not disappointed they are sturdy and comfortable.  With the "handles" on the sides of the seat they at easy to pick up and move.
