Am I crazy to want to have soft and hard (firm) surface on the same bed?
I just started to have lower back pain after waking up in the morning in the last few months. I've heard that sleeping on the firm surface helps with backpain. However I'm a side sleeper most of the time; like 1/3 sleeping on the left, 1/3 sleeping on the right, and 1/3 sleeping on my back. I have no problem sleeping on the firm surface on my back, but it's painful to sleep on the firm surface on the side. It creates too much weight pressure at the shoulders and awkward angle at the hip area. I think most men would have this problem sleeping on the side because our shoulders are generally wider than our hips. Therefore I prefer soft surface for side sleeping.
The photo shows what I have in mind to try to change my mattress; make the middle area harder (maybe put a hard foam, plywood, or something) in the blue area for back sleeping and leave the soft area on both sides for side sleeping. Has anyone ever done this? Any thoughts?
