Diamond Mattress is a family-owned mattress manufacturer based right here in Southern California, crafting quality mattresses since 1946. Every Diamond mattress is built locally in their Los Angeles-area factory, giving them direct control over materials, construction, and quality at every stage of production. At LA Mattress Stores, we carry a wide selection of Diamond Mattress models — from affordable all-foam beds to premium hybrid designs — available to test in person at all five of our Los Angeles showrooms.
What makes Diamond Mattress stand out in a crowded market is their commitment to quality materials at fair prices. As a local manufacturer, they eliminate the markup that comes with nationwide shipping and big-brand marketing budgets. The result is mattresses with CertiPUR-US® certified foams, tempered steel coil systems, and advanced cooling technology — at price points that consistently undercut national brands offering similar specs. For shoppers looking for the best value in a quality mattress, Diamond is hard to beat.
Diamond Mattress delivers a compelling combination of quality, value, and local craftsmanship. Here's why our customers love them:
Diamond Mattress offers several collections designed for different needs and budgets. Here's a guide to finding the right one:
Major national mattress brands spend heavily on advertising and maintain nationwide distribution networks — costs that get passed on to consumers. Diamond Mattress, as a local manufacturer, keeps overhead low and passes the savings directly to you. When you compare a Diamond mattress to a similarly specced Sealy or Serta at the same price point, Diamond typically offers denser foams, better coil counts, and more comfort layers.
Online mattress brands like Casper and Purple market convenience, but you're buying blind — relying on reviews and return policies instead of actually testing the mattress. Diamond mattresses are available to try in person at all five LA Mattress Stores locations, so you know exactly what you're getting. Plus, you get the same competitive pricing without the risk of a costly return shipping process.
Tempur-Pedic is the premium memory foam leader with proprietary TEMPUR® material. Diamond offers comparable foam quality (CertiPUR-US® certified, gel-infused) at significantly lower prices. If you want the absolute best in memory foam technology and budget is secondary, Tempur-Pedic is hard to beat. If you want excellent foam comfort at a much better value, Diamond is the smart choice. Visit our showrooms to test both brands back to back.

Diamond Mattress is proudly manufactured in Southern California. The company has been family-owned since 1946, with their factory located in the greater Los Angeles area. This local manufacturing means shorter delivery times, fresher materials, and direct quality control — advantages that imported or nationally distributed mattresses simply can't match.
A quality Diamond mattress typically lasts 7–10 years with proper care. The hybrid models with pocketed coils tend to last on the longer end of that range. Using a mattress protector and rotating the mattress every 3–6 months will help extend its lifespan. All Diamond mattresses at LA Mattress Stores include the manufacturer's warranty.
Yes, many Diamond mattress models are well-suited for sleepers with back pain. Their medium and medium-firm options provide the right balance of conforming comfort and supportive structure to maintain proper spinal alignment. The gel memory foam layers offer pressure relief at common pain points. We recommend testing different firmness levels in person at our showrooms to find the best fit for your specific needs.
Yes. Several Diamond models are available in compressed, rolled packaging for convenient delivery and setup.
