You can also use a good car jack -- most folk have one around or a friend/relative will have one -- no need to buy a rear stand just for this.
Just make sure your kickstand is down good and proper. Slide the hydraulic car jack under your rear shock assembly. Jack up the carjack. Done.
I've had my rear wheel/chain off for two nights supported like this, no mishaps/falls. It's basically like a tripod. Of course, I have no dogs/kids running around my garage either....
