This task chair looks great with my desk. I find it very comfortable, though the back doesn’t recline as much as I thought it wouldcould after adjusting the tension.   The hydraulic part sometimes makes a noise when you sit on the chair that almost sounds like it’s “re-seating” itself in the slot where it was installed. But, I’ve never felt unsteady or unsafe, and the up-down adjustment works just fine. Overall, I’m very pleased.
