I use the HoseBuddy Tangle Free CPAP Hose Suspension System as my permanent home hanger. It is a heavy duty hanger that is built to last. I think your house would fall down before this hanger broke or flexed. http://www.cpap.com/productpage/HoseBud ... ystem.html
For a packable travel system I use the CPAP Hose Lift System. This is a lighter duty collapseable system. Small sections with an elastic cord running through them. Think tent poles. http://www.cpap.com/productpage/flexibl ... -lift.html
I've had no problems with either hanger. I do have a small sheet of plywood at the head of my boxspring to minimize the swaying and drooping of the hangers. The plywood gives the hanger's foot something solid to support it so it doesn't sink into the mattress.
One thing to watch out for is your headboard, I have a tall headboard and the CPAP Hose Lift System just isn't tall enought to reach over the top. I can't sleep with it on the inside of the headpard (personal quirk). The HoseBuddy goes straight up and does a 90 degree bend at the top whereas the CPAP Hose Lift System goes up then angles outward. See the pictures.
Either will work, just depends on what you want/like.
