Bought two of the 20x20.  Bigger than I expected but luv it nonetheless.  Makes a great statement in black.  Transitional and timeless!  It's supposed to simulate wood.  From afar looks like wood.    Only wish that up close it looked more like wood but it's very close!  Can't comment on the water reservoir at the bottom, as I only just planted my flowers, but it does hold a lot of water.  It will be interesting to see if it works.
