We bought this for our new 6 person round dining set and I was debating 10 vs 11 ft umbrellas.  Very glad we went with the 11 as it shades all seating very well. I like the tilt mechanism, very easy to use. I was looking for something that would also vent wind well, and though we haven't had it up during a windy day yet, I am hoping it will hold up! Color looks great as well. Great deal for the price!
