These were SO easy to assemble.  The cushion is comfortable and the base is surprisingly stable, even on carpet.  I needed extra tall stools so these work great.  I am 5'2" and a petite/active woman and I do have to climb onto them at the highest setting so they might be an issue for older/less coordinated/heavier people trying to climb onto them!  If just using as a chair, they would be fine.
