In Consumer Reports' latest mattress survey of 61,000 members, almost 70 percent reported that they sleep on their sides, at least for part of the night. That's why we run extensive tests on mattress support for side sleepers.

If your partner isn't a side sleeper and you want a mattress that rates well for all sleeping positions, check out the options among the more than 150 models in our mattress ratings.

How We Test Mattresses for Side Support

In our support tests, we use people of small and large stature. (We average the results of both to produce the score for average-sized sleepers.)

For the side-sleeping score, we observe several points along each subject’s spine and measure how much they diverge from a straight line. For a test model to score well, the points must remain fairly parallel to the surface of the mattress.

“You might think that softer mattresses would be better for side sleepers, but the average firmness of the models on this list was right around 5 out of 10—or a medium-firm mattress on our firmness scale,” says Chris Regan, the Consumer Reports engineer who oversees mattress testing.

CR members can read on for ratings and reviews of standout models that provide great support for side sleepers of all sizes—and perform well overall in our mattress tests. These innerspring, foam, and adjustable air mattresses are from brands including Avocado, Casper, Charles P. Rogers, Ethan Allen, Sealy, and Reverie.
