About Diamond Mattress
Diamond Mattress has been family-run in Southern California since 1946 and is now in its fourth generation, supplying both independent retailers and its own direct lines.
The company's identity is materials-first: certified natural latex, wool and cotton in the Everyday Diamond and Nature's Bounty collections, alongside conventional hybrids for the retail channel.
Diamond also runs an unusually serious sustainability programme, including in-house recycling of old mattresses, which is rare for a manufacturer of its size. If you want a domestically built natural bed and do not want to pay Avocado or Naturepedic prices, this is a brand worth shortlisting.
What they make
Natural latex, wool and cotton hybrids, conventional pocketed-coil hybrids, and retail-channel collections; also mattress recycling.
Origin
American — manufactured in California
Diamond Mattress Signature Technologies
Natural Latex and Wool Comfort Layers
Certified latex with wool batting used as a natural fire barrier instead of chemical retardants.
Hybrid Coil Systems
Zoned pocketed coil units built in the California plant, tuned by gauge for firmness rather than by comfort-layer thickness alone.
Closed-Loop Recycling
An in-house programme that breaks down returned and old mattresses into recoverable steel, foam and fiber.
Best for
- Buyers wanting a natural-materials bed made in the USA
- Hot sleepers — latex and wool both breathe well
- Shoppers who care about manufacturing sustainability
- West Coast buyers who want a short supply chain
Not ideal for
- Memory-foam contour seekers
- Buyers who want a single nationally consistent online lineup
- Bargain shoppers looking under $600

How Much Does a Diamond Mattress Mattress Cost?
Diamond Mattress queens run $900–$3,500 across the lineup (mid to premium tier). The table below estimates the rest of the size ladder from that queen range using the standard size pricing brands apply — the low column tracks the entry model, the high column the flagship. Treat these as planning estimates rather than quotes: promotions move real street prices by 20–30% for weeks at a time.

Diamond Mattress FAQ
Where are Diamond mattresses made?
In the company's own Southern California facility. Diamond has manufactured domestically since 1946 and is still family-owned.
Is Diamond a good alternative to Avocado?
It is the closest value alternative if you want natural latex and wool made in the USA. Avocado has deeper organic certifications and a stronger brand; Diamond typically undercuts it on price for a comparable materials list.
Does Diamond recycle old mattresses?
Yes — the company runs an in-house recycling operation that recovers steel, foam and fiber from returned and end-of-life mattresses, which is unusual for a manufacturer of its size.
