This pergola is perfect for keeping the afternoon sun at bay.  We didnt want a big structure but also didnt want just an umbrella.  While the dimensions say 10x10 I think that is measured from the outermost corners.  Where the posts stand is about 8x8 which is perfect to cover a small dining set or seating area. The sailcloth is really great quality and slides easily from one side to the other.   The price is fantastic and it only took a couple of hours to put together.
