@sbtheplumber1 , you might check with a hospital bed supply store. Insurance should cover it. It connects to a pump that fills the mattress topper (which lies on top of your regular mattress) with air. As your body exerts pressure, the air expands. It’s designed to prevent pressure sores on patients who lay in bed for long periods of time without moving. The downside is that it creates a bit of noise. Also, it moved a lot and takes getting used to. I hope it gives you at least an option.
