These stools are fabulous!  So easy to assemble!  The only tool I needed to provide was a Philips Head screwdriver.... the allen wrench was included.  Took only about 15 minutes per stool.  The stools are very comfortable and look great at the island.  I ordered the red and the color is perfect, more on a dark cranberry color than true red.  I highly recommend these stools.  Sturdy and beautiful!
