Stools are well made, easy to assemble and both the seating surface and the metal finish are done well.  The stools do not retract to as low a height as I would like but that is a personal preference.  The hydraulics work well.  For my height, the placement of the footrest is a little awkward in the lowest seat position, but it is good in all other heights.  The think I like the most about the stools is the ease at which you can move them around and that they are extremely stable when you are sitting in them.
