Hi all Just tried my first night with a pressure redistribution mattress to prevent pressure sores. Wow...its noisy....is this part of the deal...is peace and quiet a thing of the past? I feel like i have spent the night being intimate with a vending machine. I used to enjoy my sleep but now that seems to be a distant memory. Does it have to be this way? Florence Nightingale would surely have something to say on the matter.
