Yeah the thing I like about Jarvis is that they don't get wobbly near the limit of their extension like some of the other standup desks I've seen. I'm 6'5" and I have a thick anti-fatigue mat, so I have to raise it very high.
On top of that I also have a 42" TV on a monitor arm and an attached keyboard tray, and still no wobble.
