Higher Quality Products: We Make It Ourselves So We Know It's Better


Better Foam = Lasting Comfort


We process, cut & convolute our own
foam right here at Diamond
The key to creating a high-quality mattress that will remain comfortable for years is the quality of foam used in the mattress. High density foam and low density foam can feel the same initially, but low density foam breaks down quickly over time, losing its support and firmness, causing sagging and back pain. In contrast, the high density foams used in a Diamond mattress do not break down over time and will provide the supportive comfort you deserve for years to come.

At Diamond, we process, cut and convolute all of our own foam so we can ensure the quality and comfort of every mattress we make. You can rest assured knowing your bed will be of the highest quality and feel just like a new bed, night after night, for years to come.

Diamond-Made Wrapped Coil Support Systems

Our individually wrapped coils do not
transfer motion & contour perfectly
We manufacture our own individually wrapped coils right here at Diamond Mattress, so we can guarantee the quality, consistency, and comfort. Our wrapped coils don’t transfer motion, so you can sleep undisturbed even if you partner moves at night. Our individually wrapped coils also contour to your body better than any other spring system, virtually eliminating painful pressure points that cause you to toss and turn at night.

With our Diamond-made individually wrapped coils, you will toss and turn less and sleep more soundly throughout the night. And because we make them ourselves, we know they are the best and we test them multiple times a day to ensure your bed will relieve pressure better and provide you with undisturbed rest.

Durability and Performance Testing

All of the products produced by Diamond Mattress have been designed through extensive research and in-depth testing. We use Rollator and Cornell testing to ensure that our mattresses will not break down over time.

10 Year Usage Test – Rollator Test
Rollator Testing simulates 10 years of usage by taking a 240 pound roller and rolling it over the mattress 100,000 times. This test takes 3 weeks of non-stop rolling to really abuse the mattress. During that time, we measure the firmness and height loss at regular intervals to measure the change over time and ensure that your mattress will never get uncomfortable body impressions or soften and cause a sagging, hammock like sensation. Through this testing we are able to prove that our mattresses will hold up far better than industry standards and will remain comfortable for years.

10 Year Abuse Test – Cornell Test
Cornell Testing is an abuse test that simulates 10 years of abusive usage by taking 240 pounds of pressure and pounding the mattress in one spot, 100,000 times. This is like having a 240 pound person jumping on the mattress in one place for 3 weeks straight, non-stop. This abuse test is a further step we take to ensure the quality and durability of all of our mattresses.
