Just checked the orientation of our bed. Head points due west, window due North, bedroom door due south. It wouldn’t be too difficult to knock up a wooden “X” frame to sit between the feet of the bed and mount an angular contact roller bearing on the base at the intersection. That would allow you to orient the bed to any point of the compass. You could also dangle your leg out of the bed and use your foot to scoot the bed around so your side is nearest the door if you need to get up in the night for a pee.
