Purchased the Kroy and it meets my needs perfectly — as I have a desk that is slightly higher than normal and this chair rises high enough to accommodate. Had minor difficulty was the assembly as one of the thirteen screws would not properly seat in the fastener. everything else was well marked and assembled smoothly.
positives: the chair is nice and fits my needs. Is the height I need Works with the adjustable desk. concern: not able to tilt forward as directions say the chair is to be able to do.
Chair is excellent. We had some difficulty with assembly and operation of the chair. Putting the casters on the feet required a lot of pressure. As for operation we tried to adjust the height using the wrong thing (it's on the right not the left).
