- I had a new patio built in which a cantilever umbrella would look and work great in a strategic spot as built in/in ground mount. It must be able to extend and rotate to three areas: one side is a swinging day bed, the other side is a grill, and the third side is a patio table. The picture here of the cantilever umbrellas would be similar to what I envision. If you could suggest how and which umbrella, I would greatly appreciate it!
