Our sleep experts have been testing mattresses, bedding and accessories for years (a few have been testing for up to eight years). At this point, we’ve tested over 300 mattresses from dozens of brands, from bigwigs like Purple and Tempur-Pedic to more niche companies like Sonu and Airweave.
Our team is comprised of bed testers with varying body weights and types, heights, genders and sleep preferences, which helps us provide an overarching assessment of each mattress from a multitude of viewpoints. Many mattresses are tested for long periods, ranging from a month or two up to five years.
We test king-size mattresses just like we would any other bed. When a new mattress arrives at our testing facility, it undergoes rigorous, hands-on testing by each of our experts. We analyze specific characteristics, including firmness, feel, temperature, motion isolation, edge support and other special features the mattress may have.
Firmness
Firmness is rated numerically on a scale of 1 (the softest) to 10 (the firmest), and we use industry terms such as soft or medium-firm to describe it. Our entire team takes turns assessing and ranking the firmness of each mattress, which allows us to make suggestions about which sleeping position and body type it best suits. After subjectively analyzing the firmness, we let our one-of-a-kind Mattress Smasher 9000 do its thing and give us an objective firmness score.

Feel
Another subjective element we review is the feel of a mattress, separate from its firmness. Does it feel springy and responsive when lying on it? Is it easy to switch positions? Or does the dense memory foam conform around our bodies and hold our shape for a while? Does the mattress have a soft, plush pillow top feel, or is it more neutral? Can we feel any coils or zoned support? We do our best to describe exactly what it feels like to lie on each bed to help you determine if it’s right for you without having to test them all yourself.

Temperature
Temperature can be tricky to review when considering each sleeper’s personal preferences and the fact that many mattress brands exaggerate their beds’ cooling capabilities. When testing and reviewing mattresses, we detail how hot or cool the mattress sleeps. Many external factors come into play here (such as climate and environment, bedding, pajamas, etc.), so we test the beds in temperature-controlled rooms without sheets or bedding. Using our extensive knowledge and experience, we analyze its construction and materials and explain how they affect the temperature.
