by Organic Mattresses Inc (OMI) makes some of the most rigorously certified organic mattresses in the US, but the price range of $2,800 to $5,500 and the lack of a long sleep trial make it a niche choice. For most organic-focused shoppers, the Saatva Zenhaven offers 100% natural Talalay latex with GOLS and GOTS certifications, a 365-night trial, lifetime warranty, and free white-glove delivery at a more accessible price.

Organic Mattresses Inc: what the brand actually offers
Organic Mattresses Inc, widely known as OMI, was founded in 2003 in California. The brand has built its reputation on strict full-spectrum organic certification: USDA-certified organic Dunlop latex cores, GOTS-certified organic cotton covers, GOTS-certified organic wool fire barriers, plus GOLS, OEKO-TEX, and Made Safe certifications across the lineup. That level of certification depth is unusual. Most brands carry one or two eco labels; OMI stacks them intentionally for buyers who need documented proof at every layer.
The current OMI lineup centers on four collections: Wildflower, Flora Nouveau, Duo, and Terra. All are all-latex constructions with no synthetic foams, no adhesives, and no chemical fire barriers. Retail pricing runs from roughly $2,800 to $5,500 in Queen, and the brand sells through specialty natural-bedding retailers and select chiropractic offices rather than direct online. That distribution model affects the buying experience: trial periods vary by retailer, typically offering no trial at all or a maximum of 60 nights.
OMI models compared
| Model | Type | Firmness | Price (Queen) | Trial |
|---|---|---|---|---|
| Wildflower | Organic Dunlop latex | Medium | ~$2,799 | 0-60 nights (retailer varies) |
| Flora Nouveau | Organic Dunlop latex | Medium-Firm | ~$3,499 | 0-60 nights |
| Duo | Organic Dunlop latex, flippable | Plush/Firm | ~$4,299 | 0-60 nights |
| Terra | Organic Dunlop latex | Firm | ~$5,499 | 0-60 nights |
Performance: what OMI mattresses actually feel like
All-latex construction gives OMI mattresses a buoyant, responsive feel that memory foam cannot replicate. Dunlop latex is denser and slightly firmer through the base than Talalay, which tends to produce a more grounded sleep surface rather than the deep contour of foam. Pressure relief across the Wildflower and Duo Plush sides is good for side sleepers, while the Terra and Flora Nouveau suit back and stomach sleepers who need firmer lumbar resistance.
Motion isolation is moderate. Latex absorbs motion better than innerspring coils but transfers more movement than slow-rebound memory foam. Couples where one partner is a light sleeper may find this worth testing in person before committing.
Cooling is a genuine strength. Organic wool batting wicks moisture, the latex core promotes airflow, and the absence of dense foam layers means OMI sleeps noticeably cooler than most foam alternatives.
Edge support is softer than coil hybrids. Latex edges compress under sitting weight, which is typical of all-latex designs. Back-and-center sleepers rarely notice; edge-sitters may.
Off-gassing is essentially zero. Certified organic construction eliminates the chemical smell new foam mattresses often produce in the first week.
OMI vs Saatva Zenhaven: side by side
| Feature | OMI (mid-tier) | Saatva Zenhaven |
|---|---|---|
| Latex type | Dunlop, GOLS-certified | Talalay, GOLS-certified |
| Cover | GOTS organic cotton | GOTS organic cotton |
| Made Safe certified | Yes (full lineup) | No |
| Trial period | 0-60 nights (retailer) | 365 nights direct |
| Warranty | 20 years | Lifetime |
| White-glove delivery | Not standard | Free, included |
| Old mattress removal | Not standard | Free, included |
| Price (Queen) | ~$3,499 mid-tier | ~$1,995 |
The trial gap is the most consequential difference. Sixty nights is borderline for confirming fit with a mattress at this price point; 365 nights is enough to experience every season and sleeping condition. If OMI is the wrong firmness, buyers with a short-trial retailer have limited recourse. Zenhaven's flippable design also adds built-in flexibility: Luxury Plush on one side, Gentle Firm on the other, without returning the mattress.
Who should buy OMI
OMI makes sense for a specific buyer. If you need the strictest possible full-spectrum organic certification across every component, including Made Safe verification, GOLS Dunlop latex, GOTS cotton and wool, and OEKO-TEX, and you are willing to pay the $2,800 to $5,500 price premium for that documentation, OMI is one of very few brands that delivers it.
This tends to describe chemically sensitive sleepers with confirmed latex or fragrance sensitivities, allergy sufferers seeking the lowest possible synthetic exposure, or parents furnishing a primary bedroom for health-sensitive family members. These buyers should ideally test an OMI mattress in person through a specialty retailer before purchasing, given the limited trial window.
Who should choose Saatva Zenhaven instead
Most organic-focused shoppers end up better served by Zenhaven. The core organic credentials are strong: 100% natural Talalay latex, GOLS certification, GOTS organic cotton cover. The trial is 365 nights, which is 300 nights longer than most OMI retailers offer. Lifetime warranty coverage is meaningfully stronger than OMI's 20-year terms. Free white-glove delivery and free old mattress removal are bundled on every order.
Where Zenhaven falls short of OMI is the Made Safe full-spectrum certification and the Dunlop latex base, which some organic purists prefer. For buyers who prioritize the GOLS and GOTS organic documentation but do not specifically require Made Safe or Dunlop construction, Zenhaven covers the important ground at roughly half the price with far stronger purchase protection.
OMI is the strictest certified organic mattress option in the US and a legitimate pick for chemically sensitive buyers who need full-spectrum documentation. For most eco-conscious shoppers, Saatva Zenhaven delivers GOLS-certified natural Talalay latex with a 365-night trial and lifetime warranty at half the price.
Frequently asked questions
Is OMI fully organic certified?
Yes. OMI mattresses carry GOLS, GOTS, OEKO-TEX, and Made Safe certifications across major components. The Dunlop latex cores are USDA-certified organic, the cotton is GOTS-certified, and the wool fire barrier is GOTS-certified. This is one of the most complete organic certification stacks available in a US mattress brand.
Does OMI offer a sleep trial?
Most OMI retailers offer no in-home trial or a maximum of 60 nights. Because OMI sells through specialty retailers rather than direct, trial terms depend on the retailer. Saatva Zenhaven offers a 365-night home trial direct, which is significantly stronger protection at this price level.
What is the difference between OMI Dunlop latex and Zenhaven Talalay latex?
Dunlop latex is denser and slightly firmer through the base, producing a more grounded, stable feel. Talalay latex goes through an additional processing step that creates a more consistent cell structure and a slightly bouncier, lighter feel. Both are natural latex; the difference is texture and response, not certification.
Where can I buy OMI mattresses?
OMI sells through specialty natural-bedding retailers and select chiropractic offices. The brand does not sell direct online, which means pricing and trial terms vary by retailer. Saatva sells direct nationwide with consistent pricing, showrooms in major US cities, and a standardized 365-night trial.
Is OMI worth the price?
For buyers who specifically require full-spectrum Made Safe certification and GOLS Dunlop latex, yes. For most organic-focused shoppers, the price premium over Saatva Zenhaven, combined with the weaker trial terms, is hard to justify unless certification depth is a firm requirement rather than a preference.
