These stools are comfortable enough, but the seat area is a bit narrow.  They were a little difficult to assemble.  The holes in the bottom didnt quite line up with the screw hole.  You have to press the frame pretty hard to get the screw to catch, as they dont seem long enough.  Then there is a cap that needs to be removed before placing the seat on the pneumatic bottom, which is not clear from the instructions.  However they are functional with a modern look.
