9 Best Mattresses of 2024, Lab-Tested and Reviewed

There are more than 250 mattresses in our ratings, each with an Overall Score that’s determined, in large part, by the model’s performance on a range of tests: sleeper support, firmness level, stabilization level, and durability. 

To test stability (also known as motion isolation), we drop a 38.5-pound weight onto the mattress and measure the vibrations at the point of impact and across the mattress. This tells us how easily sleepers should be able to shift their weight without disturbing a partner. We also test how well the mattress keeps its shape over time by using a machine that moves a 300-plus-pound wood roller across the surface of the model 30,000 times. 

The ratings for mattress comfort and owner satisfaction included in the Overall Score are based on data from survey results on almost 67,000 mattresses. To learn more about how we test and rate mattresses, and how to choose the right one for you, check our mattress buying guide.

We also recently started examining a mattress’ impact on the environment and health, taking into account a range of factors, including materials and construction, durability, owner satisfaction, and shipping footprint. Our Green Choice recommendations are designated with a green leaf icon in our comprehensive mattress ratings.
