The bottom tray does not stay - so if I put umbrella in one corner then I need to make sure that I put something else in the other so that the tray does not tilt... also, I bought this for the design and I still like it, but when I put shorter umbrellas or umbrellas with extra coverage on the top (so the extra material is sitting on the top half of the umbrella, for example), they get stuck in the room between wires...  so after all, I realized that this is not so practical... looking good, though...
