Pommel Horse in SL/PE3

Just wondering, does anyone have any alternatives for the pommel horse in SL/PE3?

I have a pretty small room in which to train so a pommel horse is out of the question and probably a bit pricey! I do have stall bars which I expect is a good start. I've had a look at back extension station but they are still pretty expensive and take up a fair amount of space.

foots in between bars (stalbars) and i have table with something soft on top ,under hips. 

I use my sofa, it has a pull out bed that I loop a belt on to. It's quite study.
