These stools are so comfortable.  I was really happy once I finally tightened all of the screws to be flush with the leg.  Assembly was a bit of a challenge.  The leg holes were not drilled deep enough and I really had difficulty putting enough torque on the allen wrenched screws.  The allen wrench kept slipping out and fortunately I had another wrench in the 2nd chair.  Hope this makes sense.  I usually have no difficulty assembling furniture.  I could have used the kind of screws and wrench provided in the sofa I had to assemble.  Assembly is the only reason I couldn't give this all 5 stars.
