Why you can trust us
Lauren Brooks is an ergonomist and sleep coach who previously worked at a physical therapy practice. For this guide we tested 11 models over 8 weeks in our test house. We bought most models ourselves; loaned units were returned after testing. Manufacturers don’t see our conclusions before publication.
Who is this for?
You buy a mattress in a box online and can usually try it for 100 nights. That’s a good option if you don’t feel like visiting a showroom.
How we tested
Testers of different heights, weights and sleeping positions slept on every mattress. We measured pressure distribution with a pressure mat, edge support and surface temperature.
