Pretty comfortable, and look as good as they do in the photos.  Seems to be a minor design flaw, though - every chair has one leg slightly shorter than the others, and it seems to be the same leg on every chair.  I tried them on my living area rug and it wasn't noticeable, but I wanted to use them in an area with hardwood.  I put furniture leg pads on the feet so they wouldn't scrape the floor (a bit tricky, since the feet are rounded), and I just used a thicker one on the shorter legs - mostly fixed it.
