Chairs get 5 stars-I was excited to find these chairs as they matched another table and chair set that I had.
Assembly 3 stars: Putting together these chairs had its challenges.  The picture of the assembly was small and quite difficult to see, so time was spent experimenting to make sure assembly was correct.  In addition, the parts (washers) were labeled incorrectly in the assembly directions.  I figured out that the washer labeled 'M' were really suppose to be 'L' for installing the back the chair to the arm railings.  

Also, the included parts were for 1 chair rather than 2 on the directions and an extra set of screws and washers were included,  which was nice but confusing.  Once all of these issues were figured out, I was able to put the second chair together with relative ease.  It's a very nice, sturdy swivel chair, but with assembling challenges.
