After all the other reviews commented about the assembly issues I found an allen wrench socket attachment - that would have been miserable with the tool they provided.  The only thing with a better tool is I overtightened a few which pushed the material up where it should have been flush.  

The only thing I couldn't figure out was the elastic pegs to hold the ottoman cushion in place -- what are they supposed to attach to?

They look great and fit well on my covered porch.
