Mine is an older version, and I think it displays differently than the new ones. At any rate, with the range being 0-100, I keep it set at 50. I have only had a loss of pressure once, and I don’t know the reason. Probably a cat under the bed, playing with the control. No experience with memory foam, if you are speaking of the pads that go on top of a mattress. My daughter thinks they’re heavenly.
