I slept in the middle of the kingsized bed initially. Figured I'd take my old side back (had given it up 4 years ago because he really wanted it) but something was funky with the mattress, so I'm back to my current side of the bed, with books on the other.
Sometimes I scooch to the middle, curl up with a soft full pillow and sleep very well.
When I get out of bed, even if it's 3 AM, I make the bed, shaking my head in wonder as I do.
