My kitchen remodel is not quite finished, but here are the stools next to the island. The seat height is 24". I would have liked the seats to be 26", but I loved the look of these stools. 
They were easy enough to assemble. Make sure the holes on the legs for the footrest screws are toward the center. I had to remove the legs on one stool to switch them. My mistake. 
Also, while attaching the footrest, I really had to wrangle the legs so the screw holes would line up. It helped not to tighten the screws holding the legs to the seat until the footrest was attached.
