Anecdotal also but I sometimes sleep alone in my office (have a futon) where it is very quiet. I usually feel fully rested after 6 hours in there versus 8 hours in bed with wife, dog and the cat occasionally coming through.

I wish culturally it was standard for houses to have something like `sleep` rooms that are optimized for that purpose.

I stopped sleeping with my wife in the same bedroom some years ago and it was great for our sleep quality.

It's very funny how people conflate that with other aspects of couples relationships.

They're called a bedroom.
