In 1960s television, why are married couples shown sleeping in separate beds?

by Bellajoey

An example of this would be The Dick Van Dyke Show. The characters Rob and Laura are married and have a son, but the scenes that take place in their bedroom show the couple sleeping in separate twin size beds.

While there’s always more to say on the subject, there was an excellent answer from u/mimicofmodes on this subject:

Did married couples actually sleep in separate twin beds as depicted in old movies from the ‘30s, ‘40s, and ‘50s? Or was it just for the propriety of the movies?
