To attempt an artificial gravity "chamber" would require an exact measure of how much gravity is exerted at a given time, and then a consistent way to multiply it. That's far out there for any engineers working on any similar projects.
To be fair though, there is a somewhat simpler, albeit still irritatingly complex and expensive, solution to your problem. Magnetics are a fantastic way to recreate such effects. What you'd need is a large, powerful magnet below you, and you'd need to be wearing metal that responds to magnetism. Pretty much all over.
This is the most feasible solution I can think of right now.
