We just received this chair.  It is simple, modern and feels well made.  The wood is not treated, so I am a bit concerned that it will show dirt on the arm rests and back if I don't apply a teak oil prior to use.
Also, we purchased this to use with a Knoll Sarrenin table.  The arm rests are < 1/4" too high to slip under the table.  We will have to either trim the bottoms of the chairs or prop the table slightly.

Pros: Comfortable and modern 
Cons: Wood is not treated
