It's easy to assemble but also easy to do wrong, like put the base on backwards. The directions it comes with barely say anything. The chair so far seems descent enough, just really wasn't impressed with the directions.
This stool replaced one that was awkward getting onto and was uncomfortable if used for any length of time. The stool was easy to assemble, comfortable and has a great height adjustment feature. The two casters that lock make it easy to store without worry of rolling.
This was such an upgrade from the little round stool, should have upgraded a long time ago. The only draw back is the plastic tray very cheap and needed to be a little wider to.
