Working with our team of testers at the USN&WR Reviews Lab in Salt Lake City, we put in hours of tossing and turning on each mattress, brand research, along with rigorous reporting on every pro and con. Plus, we polled 4,500 Americans on how they felt about these beds, and researched industry feedback amongst fellow experts. According to our research, 65% of U.S. adults say a high-quality mattress is the most worthwhile bedding product.
