What can I salvage from a deskchair with a broken base?

I’ve paid way too much for chairs over the span of my many obese years and I was sort of hoping I might be able to reuse it or parts of it. It’s a similar chair to this one: http://ak2.ostkcdn.com/img/mxc/091210_deskchair.jpg and two of the legs are broken. I glued them back on and taped them up and attached ropes to prevent buckling outward. So the wheels buckled sideways, obviously. Not that that’s really relevant…

I’m losing weight but people need to learn plastic is barely fit for making toys, let alone anything else.
