The Avocado Green Mattress is GOTS certified organic at the finished-product level, uses GOLS-certified organic Dunlop latex, and holds five additional finished-product certifications. The Birch® Natural Mattress is a natural latex hybrid that holds GREENGUARD Gold on the finished mattress and uses organic cotton, but it does not hold finished-product GOTS certification or the broader finished-product nontoxic certification stack.

Avocado Green Mattress Firmness Options
Extra Firm — our firmest tight-top model
Firm — tight-top with a no-sink surface
Medium — the sweet spot of firmness, comfort, and full-body support. Most popular.
Plush — attached Euro-style pillow top
Ultra Plush — indulgent softness, box-top design
The Birch® Natural Mattress is available in a single medium-firm option. Birch offers separate models (Birch Natural, Birch Luxe Natural) at different price points and constructions, but each individual model is available in one firmness.
Certifications: What the Difference Means
Both mattresses use natural latex and natural-material covers, and both avoid polyurethane foam and fiberglass. The distinction is in what has been independently certified — and at what level.
GOTS — the Global Organic Textile Standard — certifies the finished mattress, not individual components. It audits the entire product from fiber cultivation through manufacturing and prohibits polyurethane foam, chemical flame retardants, fiberglass, and chemical adhesives in its finished-product requirements. A brand either holds a verifiable finished-product license in the public GOTS database or it does not.
The Avocado Green Mattress holds a publicly verifiable GOTS finished-product license (CU863637), searchable at global-standard.org. The Birch Natural Mattress does not hold a finished-product GOTS certification, though Birch uses GOTS-certified organic cotton at the material level in the cover.
GREENGUARD Gold — which both mattresses hold — certifies against chemical emission limits for bedrooms and living spaces. The Birch Natural Mattress also references eco-INSTITUT® certification on its Talalay latex (typically applied at the latex supplier level). Neither certification is equivalent to finished-product organic certification, and neither alone covers the broader set of substances tested under MADE SAFE®, EWG Verified®, or OEKO-TEX® Standard 100 Class I.
Avocado mattresses are simultaneously certified against four additional finished-product standards that Birch Natural does not hold: OEKO-TEX® Standard 100 Class I screens against harmful substances at the most restrictive classification, designed for products used by babies and toddlers. MADE SAFE® screens against thousands of substances known or suspected to harm human health, aquatic life, and wildlife. EWG Verified® requires full ingredient transparency and health-based screening. UL® Formaldehyde-Free independently verifies the absence of added formaldehyde or formaldehyde precursors. Each standard tests for different substances through different methodologies, so that fewer gaps go unchecked.
Materials: What Each Mattress Contains
The Avocado Green Mattress is built around GOLS-certified organic Dunlop latex as its primary comfort and support material, sourced from Avocado-owned farms in India and Guatemala. Organic wool provides natural temperature regulation and serves as a flame barrier, eliminating the need for chemical flame retardants. The ticking is GOTS-certified organic cotton across most models; the Ultra Plush features a ticking with a 3% elastane blend. Coil counts go up to 1,379 fabric-encased coils across multiple firmness zones, with hand needle-tufting securing the comfort layers without chemical adhesives.
The Birch® Natural Mattress uses natural Talalay latex (approximately 2 inches) over an individually wrapped coil base, with a wool flame barrier and an organic cotton cover. Birch is owned by Helix Sleep, which manufactures the mattress in the United States. Birch's Talalay latex is sourced from Talalay Global, the latex supplier most commonly referenced in eco-INSTITUT documentation for that material category.
On latex volume: at approximately 2 inches, the Birch Natural contains meaningfully less natural latex than the Avocado Green Mattress, which uses between 3 and 6 inches, depending on the model. Latex is one of the most expensive components in a natural mattress, so latex volume is a useful indicator of where construction tradeoffs were made.
PFAS Testing
Avocado screens for 679 PFAS substances at parts-per-billion sensitivity across core materials and waterproof protectors. No detectable amounts have been found. Full results — substance list, methodology, and findings — are published publicly in our Help Center. Avocado was among the first mattress brands to publicly publish comprehensive PFAS test results.
Birch® has not published comparable PFAS test results.
Warranty and Trial
Both mattresses carry a 25-year limited warranty. The Avocado Green Mattress offers a 365-night sleep trial. The Birch Natural Mattress offers a 100-night sleep trial. For an organic mattress purchase, the longer trial gives more time to evaluate a sleep surface across seasons and through any initial adjustment period.
Frequently Asked Questions
Is the Birch® Natural Mattress GOTS certified?
No, not at the finished-product level. The Birch Natural Mattress is not listed as a GOTS-certified finished product in the public GOTS database. Birch uses GOTS-certified organic cotton in the cover, which is a material-level claim, not a finished-product certification. For a detailed explanation, see Are Birch Mattresses Certified Organic?
Is the Birch® Natural Mattress an organic mattress?
A mattress can be marketed as organic only when the finished product has been independently certified to a recognized organic standard such as GOTS. The Birch Natural Mattress contains organic materials at the component level but does not hold a finished-product organic certification. Birch's product marketing describes the mattress as "natural" — a term that is not regulated in the United States and does not require independent certification.
How much latex does each mattress contain?
The Birch Natural contains approximately 2 inches of natural Talalay latex. The Avocado Green Mattress contains between 3 and 6 inches of organic latex, depending on the model — 3 inches in the Medium and Firm models, 5 inches in the Plush, and 6 inches (combining GOLS-certified Dunlop and FSC-certified Pure Talalay) in the Ultra Plush.
What is EWG Verified® and why does it matter?
EWG Verified® is an independent standard from the Environmental Working Group that requires full public ingredient disclosure and screens the finished mattress against EWG's health-based criteria — including prohibitions on chemical flame retardants, fiberglass, PFAS, and PVC. The Avocado Green Mattress is EWG Verified®; the Birch Natural Mattress is not. For a full explanation, see What EWG Verified Means on a Mattress.
Can I verify Avocado's GOTS certification?
Yes. Avocado's GOTS license (CU863637) is publicly searchable in the GOTS certification database at global-standard.org.
How many firmness options does the Avocado Green Mattress offer?
Five: Extra Firm, Firm, Medium, Plush, and Ultra Plush. The Birch® Natural Mattress is available in a single medium-firm option.
How do the sleep trials compare?
The Avocado Green Mattress offers a 365-night sleep trial. The Birch Natural offers 100 nights. Both carry a 25-year limited warranty.
Does the Avocado Green Mattress contain fiberglass?
No. Avocado mattresses do not contain fiberglass. Organic wool serves as the natural flame barrier, meeting federal flammability standards without chemical flame retardants or fiberglass.
Where is the Avocado Green Mattress manufactured?
Every Avocado organic mattress is handcrafted and hand needle-tufted at our GOTS-certified manufacturing facility in Fullerton, California, with domestic and imported materials.
