We want you to love sleeping on your Diamond Mattress as much as we loved hand-crafting it, which is why every purchase comes with a 120-night at-home sleep trial. This gives you plenty of time to experience the comfort and support of your new bed and decide if it’s the right fit for you. We recommend trying it for at least 30 nights to allow your body time to adjust. If you have a change of heart, no problem—returns or exchanges are easy within the 120-night window, starting from the day your mattress arrives. Click here for trial terms.
Diamond Mattresses meet the most stringent certification standards, ensuring safe, non-toxic materials, a healthier sleep environment, and sustainable practices for your peace of mind and are fiberglass-free. All our foams are CertiPUR-US certified and mattresses hold Greenguard Gold certification.

THE SCIENCE OF INTEGRAMESH®
IntegraMesh is the reinforcing technology that runs through the middle of the gel grid. It keeps the grid stable so it never wobbles, while still letting it flex and respond to your body. Over time, it also helps the grid hold its shape — so your support stays strong for years.
