We have had two of these stools now for around 6 months.  They came nicely packaged and there was no initial damage.  They do come un-assembled, but assembly is fairly quick and easy with appropriate tools. Some bolts are a little challenging to torque down, but with a little extra time, were not a problem.  After preliminary connection of the legs, be sure to take a minute to double check that all legs are flat on the floor before you tighten all the leg bolts.  This should help any "wobbling" down the road.  After 6 months, they have held up very well.  These are very comfortable and used daily in our kitchen.  Initially, they did not scratch the vinyl laminate flooring but to be safe, I purchased felt floor protectors from a local "hardware" store which are attached to the bottom of the legs.  As long as they remain durable in the next 6-12 months, I plan on purchasing 2 more to have for larger gatherings.
