The CNET Sleep editors have tested more beds than the average sleeper. Around 200 different ones, in fact, and we’ve dedicated hundreds of hours to the craft. The main consideration we take into account when we look for the best mattress for side sleepers is firmness and the amount of pressure relief a mattress offers. When testing mattresses, we lay in each sleeping position (including side) and determine how well they accommodate our primary pressure points. When we’re on our side, it’s crucial our hips and joints feel properly cradled. If a bed’s too firm, it can press into your pressure points and cause soreness or pain.
Other key factors we test are edge support, motion isolation and temperature. Edge support is how strong the bed’s perimeter is, which is important if you sleep with another person or hug the edge of the bed. Motion isolation is how well a mattress dampens movement across the surface. We test this by having two testers roll around and bounce on the bed.
Everything we assess is recorded and compared to our year’s worth of data, allowing us to compare and rank beds accurately.
