My wife and I really like the Rattan conversation set.  The installation took time but was doable.  Break it down into days and your body will thank you! Thank God, I have a multi-bit manual screwdriver that had the hex-bit the size of the Allen wrench that came with the unit, assembly with the Allen wrench alone would have been arduous at best.  Do not use power tools!  You need to be able to adjust the alignment of each unit's pieces, so a manual tool is best.  The instructions and the prepared screw holes were all correct which was great!  We did not notice that we would be receiving a "tarp" to cover the unit to protect it from rain.  This was a nice surprise.  We would recommend this unit and manufacturer.  Thank you.
