The Diamond Difference

Diamond is different. We're a fourth generation family-owned and operated company that has been handcrafting mattresses in the USA since 1946. We care about our customers and our products, which is why we focus on quality, value and promoting the importance of a good night’s sleep and its beneficial effects on your health.

Our Passion: Making Mattresses You'll Love

Today we continue the tradition set forth by my great grandparents who started Diamond Mattress over 65 years ago. My father, sister and myself are here every day working with over a hundred Diamond team members to make the finest quality, most comfortable mattresses available. We take our time to design each mattress, blending the finest materials to meet the comfort level our customers want and to do it at a great value.

Our Quality: We Do It Ourselves So We Know It’s The Best

We’re passionate about making quality products that will stand the test of time. You spend over 1/3 of your life in bed and having a quality mattress that will provide pressure-relieving support is essential for rejuvenating the body and promoting health.

That’s why we control our own production lines and are vertically integrated to make sure you receive the best quality:
What's more is that our low overhead allows us to offer our customers a better quality product for hundreds of dollars less than the major brands. We can do this because own all of our trucks, equipment and buildings so we don't have high interest and overhead costs and can focus on offering a better mattress at a great value.

Our Culture: We Want Our Customers To Be Satisfied

We want our customers to be happy with their Diamond mattress and have a great experience with our company and products. That’s why we offer an industry leading 20 year warranty and focus on treating everyone like part of Diamond’s extended family. Taking care of our customers, employees, and suppliers to build lasting, meaningful and beneficial relationships, is not just good business. It makes life enjoyable.

At Diamond, we talk often about how we spend 1/3 of our life at work and after 65 years we’ve learned that treating people well always pays off in the end. That’s why we never sacrifice our quality or service. My great grandma Pearl always told us, “Never compromise quality to make a quick buck. Make a great product, offer great service and people will come back again and again.” It's the philosophy we've lived by for 4 generations and has made Diamond California's largest independent mattress manufacturer.

We hope you’ll be one of the millions of people to enjoy a Diamond mattress.
