HTTP/1.1 418: I'm a teapot
I'm pretty sure this wouldn't work.
Work? Well, setting aside points where the blood flow may be cut off, it looks reasonable from what I can see. She can relax a few of the ropes by spreading her legs even further, but that doesn't look like anything that would help her at all.
I meant the desk not toppling over. It's one of those kinds that's supported by the one continuous piece of bent metal, and I feel like her being strapped to it would make it automatically tip over (forward). Especially considering her body's position.
