For me, the most telling thing about this footrest is that in the few days I've been using it, I've not once had the urge to sit cross-legged in my chair (which makes my knees ache, so that's a good thing).

I'm not an idiot but this thing is not 'idiot' proof - normally I'd tell folks to RTFM on how to use but..

I love this thing.

A pain in the arse to move around (good thing) as it does stick to the carpet very well

A great thing to have under your desk.

so it cause me to shift position which is a very good thing
