We are owned and operated by GoodMorning.com. We hire 3rd-party engineers and use public data to rate mattresses on over 25 criteria we believe important. Brands we own—Douglas, Full Moon by GoodMorning.com, Logan & Cove, and Novosbed—are reviewed and advertised where indicated. Views expressed here are our opinions only. Full details.

At Mattress-Reviews, we understand that it is absolutely crucial that the information we provide is accurate. So, in 2017 (August/September), 2018 (May/July/December), 2019 (March/July/September), 2020 (February/June), and 2021 (September) we commissioned professional engineers from either Pure Mosaic Ltd., Rus-Tec Engineering Ltd., or Techtree Engineering Ltd. to provide third-party testing for a range of mattresses in order to test their firmness, edge support, motion isolation, and bounce.

The third-party engineers employed by Pure Mosaic, Rus-Tec Engineering, and Techtree Engineering approved, stamped, and followed a strict testing methodology.

The link below shows the mattress testing methodology as well as the mattress testing results report.
