I bought a sleeping bag for a trip to Scotland. From 12 degrees Celsius down I have frozen, but I am also an absolute frostbite! Other freeze as not intended. But for a backpacking trip he is certainly not geeiget because relatively heavy. I am also in my Thermarest self-inflating sleeping pad always rumgerutscht and therefore could hardly sleep, but that's at today sleeping unfortunately so that the surfaces are as smooth (have now bought a good sleeping bag, because the surface is so smooth !). I got the tip, a few points glue to do the sleeping mat in order not plan rumzurutschen. This could therefore provide a remedy.
