I'm reminded of my polish neighbors when I was growing up where the half-crippled old lady next door had gotten furious with her husband and was moving mattresses around to set up her own bed in the spare room because she couldn't stand to be in the same room as her husband.

I also remember back when I was doing extreme business development and my phone was a portal to the "island of misfit toys" and talking with an inventor who thought he'd cracked the code of managing temperature at sleep and was supposedly a year out from releasing a revolutionary bed that looked like a UFO on Amazon and... it didn't happen.
