Instead of buying expensive special stand that are nitro safe, get a standard cheap 10 dollar stand, remove the tubing, and get an old T-Shirt (make sure it's cotton) or something, and just cut it into strips and wrap the cloth around the places where the tubings used to be. Use rubber bands or cotton threads or double stick tape (the foam one works great and provides extra cushion) to secure the cloth. That way you get a stand that is nitro safe for not a whole lot of money.
