Pros: suited perfectly for my VariDesk adjustable standing desk (obviously--same product line), has the "wobble" feature so you are forced to use your core to keep yourself upright

I have used this Varidesk now for several months - love it!

VariDesk was great with the return, though, and I had no issues or out-of-pocket costs to try this chair out and then return it if I didn’t like it.

I feel safe on it because my heels rest on the chair's "foot" so I'm holding it in place as I lean back on it.
