I love this umbrella so far.  I got it to go over a sectional on my patio.  I wouldn't leave the house without putting it down as it seems pretty flimsy in the wind, but I suspect it has to be that light in order to keep it from tipping over.  The base is very sturdy and easily fills/drains with water (top plug for filling and side plug for draining).  I was amazed at how quickly the umbrella can be deployed and folded up.  The post swivels with a foot pedal lock so it can be adjusted for sun movement. Pic is kind of dark, but you can see how well it works with a sectional.
