For a post-menopausal couple, a single bed is fine. There is no concern of marit ayin.

Women do occasionally become niddah after menopause (as a result of certain gynecological procedures or conditions), and a couple should not share a bed on Yom Kippur or Tisha B’Av. For those rare occasions, an alternative sleeping arrangement (e.g., a guest bed, a couch, or an air mattress) should still be available for one spouse.
