My Otis would totally spread his fat ass out over all the egg cartons and purr.
Update to this.
I notice this post from me was from July 2020.
In August I moved, and one of my purchases was a Purple bed. Basically the most comfy wonderful bed ever.
I tossed Otis on it day 1. For a moment he was getting ready to waddle off, took 1 and a half steps, and hasn't moved since.
When I go to bed, both Roland and Otis are stretched out sideways, taking up about 80% of the middle, leaving 10% on either side of them.
I've adjusted to not rolling over, either when I first get into bed, or when they climb on top of me, pining me down for the next 6 hours.
