I have been on CPAP for 2 years. I keep mine on the floor. I have a homemade fleece covering over the hose and I have a HOZEBOSS which is a simple device held on to the headboard or wall with a command strip so it removes without damage and allows me to turn etc without problems. I got 2 (1 for travel) from Amazon and it has been the best asset. The pole type devices are both in the way and flimsy. I am going to look for that water pillow however. CPAP will improve your life.
