Unlike other reviews, we found the small rachet type tool, to tighten the bolts, amazing - whoever invented this, is a genius, it would have taken a lot longer without, so use it.  It took 3 hours to assemble (two people) - very impressed by the instructions.  Just a bit of organisation needed to build.  Do not empty the boxes, keep all parts in their respective box whilst you build, otherwise it makes it harder to follow the instructions.  Let's face it, its a honking bit of furniture, so it is going to take time to build, but totally worth it.  Comfortable, looks more expensive than it was, would recommend.  Buy a cover for it, to protect.
