As a travel writer, I spend a lot of time in other people's beds. While that statement is not nearly as salacious as it sounds, the reality of being on the road half the year is that I fall asleep on hotel, Airbnb, and friends' guest room mattresses just as often as I do my own. And lucky for me, I'm often checking in to five-star properties outfitted with the cushiest bedscapes. Over the years, I've developed a habit of pulling up the sheets on the most comfortable mattresses to get a peek at their label. All of this experience has made me a bit of an expert at judging what makes a genuinely superior one, which recently came in handy when my husband and I purchased a new home and needed to furnish it virtually from scratch.
