Very easy to build with the enclosed ratchet, and the extra screws etc. made it conveniently easier. It’s beautiful and versitle in arrangements. The quality is equivalent to the price, the plastic of the weave of the chairs is much thinner than a more expensive set I purchased a few years ago. 
The backs are very low so, I use a lumbar pillow above the back pillow for a head rest. It stays in place by the deck railing. If the set were bigger, it would be more people friendly, meaning, it IS quite small as previous folks have said. Consequently, I purchased two sets. I’ve put part of my larger set alongside of it for tall friends. All in all, I am happy with it.
