We purchased three chairs. They were easy to assemble. The chairs are well constructed, solid and have a quality finish.  As the instructions state, do not tighten all of the bolts until the chair is fully assembled.  I would encourage you to have someone sit in the chair when one accomplishes the final tightening that way you can ensure all for legs are even footed on the floor.  I highly recommended these bar stool.  Don’t be concerned with “rubber wood” it is a hard wood similar to Birch.
