Diamond Mattresses

What Is a Diamond Mattress?

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.

Benefits of Diamond Mattresses

Diamond Mattress delivers a compelling combination of quality, value, and local craftsmanship. Here's why our customers love them:

• Made in Southern California: Every Diamond mattress is manufactured locally, which means shorter supply chains, fresher materials, and a lower environmental footprint. You're supporting a local family business with nearly 80 years of mattress-making expertise.
• Exceptional Value: Diamond Mattress delivers premium materials — high-density foams, pocketed coils, gel cooling layers — at prices 30–50% below comparable national brands. This is one of the best dollar-for-dollar mattress values available.
• CertiPUR-US® Certified: All foams used in Diamond mattresses are independently certified for content, emissions, and durability. This means no harmful chemicals, low VOC emissions, and foam that's built to last.
• Advanced Cooling Technology: Many Diamond models feature their proprietary cooling gel foam layers and breathable cover fabrics, making them an excellent choice for hot sleepers in the Southern California climate.
• Wide Range of Options: From budget-friendly foam mattresses to premium hybrid models with pocketed coils, Diamond Mattress offers something for every sleep preference and price range. They also offer bed-in-a-box models for convenient delivery.
• Quality Construction: Diamond uses multi-layer construction with high-density base foam, targeted support zones, and comfort layers that rival mattresses at twice the price. Their attention to build quality ensures long-lasting performance.

How to Choose the Right Diamond Mattress

Diamond Mattress offers several collections designed for different needs and budgets. Here's a guide to finding the right one:

• Mattress Type: Diamond makes both all-foam and hybrid mattresses. All-foam models offer deep contouring and motion isolation at lower price points. Hybrid models add pocketed coils for better airflow, edge support, and responsive bounce.
• Firmness Level: Diamond mattresses are available in plush, medium, and firm options. Side sleepers generally prefer plush to medium for hip and shoulder relief. Back sleepers do well with medium to medium-firm. Stomach sleepers should choose firm for proper spinal alignment.
• Cooling Needs: If you sleep hot, look for Diamond models with gel-infused memory foam and breathable cover fabrics. Their cool gel foam mattresses are specifically engineered for temperature regulation.
• Budget: Diamond's range starts with affordable foam models and scales up to premium hybrids. Even their entry-level mattresses feature quality materials and solid construction — they simply use fewer specialty layers.
• Body Weight: Heavier sleepers (230+ lbs) should consider Diamond's hybrid models with reinforced coil systems and high-density comfort layers for adequate support. Lighter sleepers can choose any model that matches their firmness preference.

Diamond Mattress vs. Other Brands

Diamond Mattress vs. National Brands

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.

Diamond Mattress vs. Online Brands

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.

Diamond Mattress vs. Tempur-Pedic

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 FAQ

Where are Diamond mattresses made?

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.

How long does a Diamond mattress last?

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.

Are Diamond mattresses good for back pain?

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.

Does Diamond Mattress offer a bed-in-a-box option?

Yes. Several Diamond models are available in compressed, rolled packaging for convenient delivery and setup. These bed-in-a-box mattresses use the same quality materials as their uncompressed counterparts. At LA Mattress Stores, you can test the actual mattress in our showroom before purchasing, and we'll deliver it to your door with free white glove delivery service.
