Heading out on a hunt for the best mattress at your local store can do wonders for helping you sniff out the bad mattresses from the good ones, but simply lying on a bed for a matter of seconds isn't nearly enough to help you actually make an informed decision. Every bed-in-a-box mattress below has been personally tried and tested by one of our expert team, putting the claims of the brand to the test, and giving you our insights based on five years of experience in the mattress game. At the very beginning, we set up a mattress emporium of sorts to replicate the experience of testing a mattress in the store.
