They are usually 2 to 4 inches thick and designed to lie on top of your mattress, providing a cooler surface for your body to interact with.

While lying on the mattress topper, our testers rate comfort and support in their preferred position.We then use this data to give the topper ratings for each of our performance categories.

Testers lie down on the mattress topper and move across the surface while we use heat guns, pressure mapping tools, and VOC meters to test for temperature control, pressure relief, and off-gassing, respectively.We test each topper on a medium soft (4) mattress, a medium (5) mattress, a medium firm (6) mattress, and a firm (7) mattress to ensure well-rounded ratings. All mattress toppers we test in OneCare Media’s Seattle office undergo rounds of testing for several performance criteria.
