This is a very light and yet very strong bar stool,  the change in height is easy and smooth, the look is just as the picture, 4 wing nuts and it was ready to use.

For a metal bar stool it is not bad at all.. comfort rating I would give it a solid 8.
if the foot rest was kicked out a bit further it would be a 9.
and if the seat was a tad bigger I would give it a 10 all day.

Overall looks, quality and comfort = 9.5
