This piece was fairly easy to put together; it only took about 20 minutes.  I do like the wheel feature.  I know it is hard to stipulate how much will fit, but my chaise and 2 tall chair cushions (which are fairly thick) just made it. Describing it in gallons means nothing to me.  Perhaps they could also picture real cushions and other yard "things" so folks could get an idea of how much it will actually hold.  I have yet to have it out in the rain, so can not comment on its water tightness.
