That is an issue that the Klymit Intertia X-Frame ultralight inflatable sleeping mat was designed to address. It has various cut out sections in it which allow the down in the bottom of your sleeping bag to stay uncompressed in those specific areas, and loft up into them (you use it inside your sleeping bag), providing much greater warmth that you can get with sleeping mats that go under your sleeping bag.
