Thermarest xlite. When I sleep on my back, my shoulders and butt push down, which causes the pad to pop up into the small of my back. Like a bend over backwards motion. This goes away if I under inflate it. However if I do that my hip bone sinks into the ground when sleeping on my side.
Admittedly it’s because I’m overweight.
Anyone else have this problem? Is there one that’s comfy for back AND side sleep?
