Four reasons Diamond has been the best value in LA mattresses for 80 years — from the family that still builds them by hand, a few miles from your bedroom.
Every Diamond mattress is built in their LA-area factory. Shorter supply chain, fresher materials, and direct quality control at every step.
All foams independently tested — no formaldehyde, no heavy metals, no PBDE retardants, low VOC. One of the most meaningful certifications in mattresses.
No nationwide shipping markup. No big-brand ad budget. Just quality materials at honest prices from a family business that has been here since 1946.
Gel-infused memory foam layers and breathable covers engineered for the LA climate. Sleep cool without paying a premium.
Most mattresses you see online are made on the other side of the country — or the other side of the world. Diamond has been building them in the LA area since 1946. That’s 80 years of local manufacturing, family ownership, and direct accountability. When something is wrong, you can visit the factory.
Most “cooling” mattresses are marketing. Diamond’s cooling line is built specifically for hot sleepers in Southern California — gel-infused memory foam layers, phase-change cover fabrics, and open-cell support cores that move air instead of trapping it.
From the most popular hybrid pick to the cooling gel foams built for LA heat — every construction starts at honest value pricing.
Filter by type, firmness, size, and price.
When you compare spec-for-spec, the difference usually isn’t the mattress. It’s the marketing budget baked into the price.
At $299 to $1,499, Diamond is the best value in LA — but you should still feel it before you commit. Test every type side by side at any of our 5 LA showrooms.
