The 15 Best (and Worst) Mattresses You Can Buy Online

Shopping for the best mattress online is a waking nightmare, and picking the wrong one can literally cause bad dreams or kill your back. It doesn’t help that the online market is flooded with options or that there are more dedicated mattress review sites than stars in the sky. It’s a mess.

WIRED is not a dedicated sleep site, but we did fill a room with 25 of the top mattress-in-a-box models and spent several days unboxing, examining, reclining, and even jumping on each of them last year. Since then we’ve tested about a dozen more. Below are my favorite (and least favorite) mattresses right now. All of the prices shown are for queen-size models.

Be sure to check out our many other buying guides, including the Best Sound Machines and our roundup of the best gifts for people who like to sleep.

Updated November 2021: We’ve added the Awara, Keetsa, Avocado Green, and MyGreenMattress for kids, and upgraded the Casper to runner-up.
