Strong plastic deck box with useful internal dimensions for outdoor seating cushions.  After reading reviews I decided to caulk the box as I built it, which resulted in a good round all the joints to prevent water seeping or blowing in.  It fitted together well and the self-assembly was simple enough although the diagrams in the instructions weren't very clear and although they were labelled well all the nuts and bolts were different sizes so you need lots of spanners to assemble it.  So far seems ok, can't vouch for longevity yet.
