These chairs look perfect!  I have a black and white striped rug, and although the chair stripe is more of a dark gray than black they pick up the stripe nicely.  They are not really comfy chairs (the seat is harder than I generally like), but the back of the chair offers surprisingly great support.  The chairs were held up in shipping, and customer service was very, very responsive.  They were easy to put together, the directions were very straightforward, and there were only two slightly wonky corners on two of the chairs.  That issue was resolved by common sense.  Great experience.
