Mine is at a medium pressure (12-14) and it sometimes comes off. Usually when I am having a restless night. The hose gets caught under an arm or a pillow and moving around gets it pulled off. I've reduced the occurrences by routing the hose from behind the bed through my slatted headboard instead of from the side. Experiment until you're comfortable. I've had to make many adaptions over almost 30 years and can usually manage to make it work.
