The adjustable buckle actually stays put on my chair, which I didn't expect from something this simple. I get in a few leg presses during slow conference calls without anyone noticing. Clip-on, clip-off takes two seconds when I need to stand up.

I clip this onto my desk chair between classes and squeeze in some leg work while grading papers. The fast clip-on design means I can move it to my couch in the evening without any hassle.

The buckle adjusts in seconds, so I can switch it between my dining chair and the couch without any fuss. It clips on tight enough that I actually forget it’s there until I’m doing my reps.
