Ventured to the beach for the first time yesterday but think I need to get a sun shade. I will need to be able to fit 2 chairs under it and it needs to be quick to put up and down. I don't really care if it has a floor or not. I am really hopeless with those things that fold up into a circle and a lot of the ones I've seen do that, in fact I have one of those in the garage somewhere that I never use. Any recommendations?
