We got 5 white ones to put at our marble peninsula. I had been worried that the arms might not fit under the counter, and the stools would stick out too far.  That's not the case at all -- they fit and they look nice.  The adjustable height feature is nice and the footrests work just fine.  They seem pretty stable -- my seven year old twins squirm around a lot, and the stools haven't been wobbly that I've noticed.  If you're sitting with your rear all the way at the back of the seat, then you get decent back support.  But if you're sitting to far forward, there's not much back support if you need it.
