Hotel Beds Are Disgusting
It's bad enough that most hotels don't change the bedspreads between guests (only the sheets), but did you know that the mattresses themselves are probably pretty filthy as well? Many hotels don't use waterproof mattress covers to protect the mattresses from the millions of skin cells, bodily secretions, bacteria, dust mites, and other allergens that guests leave behind.
And as for those not-so-fresh bedspreads, Reneta McCarthy, a lecturer at Cornell University's School of Hotel Administration, tells CNN, "Is it possible that a bedspread might only be changed four times a year? Yeah, it is." Sweet dreams!
