Best Mattresses-in-a-Box

We filtered for mattresses-in-a-box in our ratings, and picked the models with the highest Overall Score, determined by our rigorous lab tests and member survey responses. Below, we highlight eight mattresses-in-a-box, including four innersprings and four foam models. In our mattress ratings, you can filter for mattresses-in-a-box models, as well as for other criteria.

We put mattresses-in-a-box through the same rigorous testing we use for all mattresses. Our mattress tests cover support for back and side sleepers, durability, and stability. For example, to test how durable a mattress is, we pass a 309-pound roller over each mattress 30,000 times to simulate use after eight to 10 years. There’s no noticeable difference in performance between our top-rated mattress-in-a-box models and traditional models, according to Chris Regan, the senior test project leader who oversees CR’s mattress tests. In fact, all the mattresses featured here earn an excellent rating for durability.

We also include brand ratings on comfort and owner satisfaction from our member surveys on nearly 67,000 mattresses. Almost every mattress-in-a-box listed here receives solid ratings for both comfort and owner satisfaction. To learn more about how we rate and test mattresses, check our mattresses buying guide.

Innerspring mattresses combine coils with layers of fiber padding, foam, or latex. These mattresses offer a buoyant feel. Many innerspring mattresses, including most on this list, have lower stabilization ratings than foam mattresses in our ratings, so there may be more motion transfer from a partner’s movements.

Most foam mattresses-in-a-box, like the Casper Original, are made with synthetic foams. But three of our four top picks consist of latex, a typically more durable material. Foam mattresses generally receive higher marks than innersprings for stabilization, so there’s little motion transfer when a partner shifts position.
