The chairs arrived by the expected dated, well packed and easy to assemble.  No extra tools are needed to assemble.   The chair rotates 360 degrees and is adjustable which was my main reason for purchasing this style.  The stool is sturdy, looks nice, and not oversize for under the counter storage.  
My only complaint is the seat is not as comfortable as I would like, perhaps if it were made slightly larger or have contour to the wood.  Overall I'm happy with my purchase.
