Easy to put together I was missing some washers for the last chair i put together .. that put me out a little!!  I went to the hardware store next day and got them.   Just frustrating.  They also wobble . I was able to adjust that by adding some felt to the bottom (not to the  bottom of the slider)  but rather in between the bottom of the chair itself and the slider..  I put a hole in the felt with a punch and screwed in the slider, this made it so the slider doesn't move every time the chair is moved . Worked perfect!  It was an easy fix. But took what I call some "Street Engineering" !  They look beautiful~
