The Buying Guide

Now you know the problem.
Here's what to look for instead.

The research is clear. Conventional mattresses are loaded with chemicals that off-gas, leach, and accumulate over time. This guide translates that science into a simple framework for finding a mattress that actually supports your health.

Read the underlying research first
Section 01 — Materials

Seek these. Avoid those.

Materials determine everything — what off-gasses, what leaches, what accumulates. This is the single most fundamental thing you can evaluate.

🌿
Materials to Seek
Naturally derived, low-emission, long-lasting
🌳
Best Choice
100% Natural Latex

Derived from Hevea tree milk — not petroleum. Naturally resilient, breathable, and inherently resistant to dust mites and mold without chemical treatment. Critically, it does not degrade into microplastics. Look for GOLS certification and confirm it's not synthetic or blended.

🐑
Best Choice
Certified Organic Wool

Naturally flame-resistant without chemical treatment — one of the only materials that can meet federal fire regulations without chemical additives. Also naturally moisture-wicking and temperature-regulating. Look for GOTS-certified wool and confirm it isn't backed with chemical batting.

🌾
Best Choice
Certified Organic Cotton

Used for covers, ticking, and comfort layers. Grown and processed without synthetic pesticides or chemical finishes. GOTS-certified organic cotton is the gold standard. Does not off-gas.

🔩
Good Option
Pocketed Steel Coils

An inert, non-emitting support material. Individually wrapped coils provide motion isolation and airflow. Pair with organic comfort layers for a fully low-chemical mattress.

🌱
Good Option
PLA (Polylactic Acid) Fiber

A plant-derived fiber increasingly used as a clean flame barrier alternative. Made from fermented plant starch, it provides fire resistance without halogenated or organophosphate chemicals. MADE SAFE approved.

Materials to Avoid
Petroleum-derived, high-emission, chemically treated
🛢
Highest Risk
Polyurethane Foam

Found in the vast majority of conventional mattresses — including "memory foam" and "plant-based foam." Petroleum-derived, highly flammable, a major source of VOC off-gassing, and degrades into microplastics over time. Requires chemical flame retardant treatment that compounds the exposure.

🧪
High Risk
Chemical Flame Retardants

PBDEs, OPEs, chlorinated retardants — these leach slowly over years and can't be aired out. Linked to hormone disruption, neurodevelopmental damage, and cancer. Manufacturers are not required to disclose which ones they use.

🪟
High Risk
Fiberglass

Used as a cheap flame barrier in many budget mattresses. Safe when fully sealed — dangerous when the cover is ever removed or worn. Tiny inhalable glass fragments can contaminate an entire bedroom. Multiple states have moved to ban it.

⚗️
High Risk
PVC Covers & Vinyl Coatings

Used in waterproof mattress covers and crib mattresses. As PVC is exposed to heat and moisture — both present in normal sleep — it leaches phthalates and heavy metals that disrupt hormones and childhood development.

🧴
Caution
Synthetic or Blended Latex

Often marketed as latex but derived from petroleum-based styrene-butadiene rubber (SBR). Blended latex mixes natural and synthetic. Only GOLS-certified 100% natural latex is genuinely clean — "latex" alone means nothing.

Section 02 — Certifications

The certifications that actually matter

Third-party certifications are the most reliable signal available — but they vary enormously in scope. Here's what each one actually covers, and where its limits are.

✓ Trust
GOTS
Global Organic Textile Standard

Covers the entire textile supply chain from field to finished fabric. Prohibits chemical flame retardants, polyurethane, and hazardous dyes. One of the most comprehensive certifications available.

Organic fiber sourcing
No chemical flame retardants
No polyurethane
Processing & manufacturing
✓ Trust
GOLS
Global Organic Latex Standard

Ensures latex content is at least 95% organic and sourced from certified rubber plantations. Prohibits chemical flame retardants and polyurethane. Essential for any latex mattress.

95%+ organic latex content
No chemical flame retardants
No polyurethane
Farm-to-product traceability
✓ Trust
MADE SAFE®
Nontoxic Certified

Screens against thousands of known toxic chemicals. Prohibits flame retardants, fiberglass, PFAS, and phthalates. Among the most rigorous consumer safety certifications for mattresses.

Thousands of chemicals screened
No fiberglass
No PFAS
No chemical flame retardants
✓ Trust
Oeko-Tex Standard 100
Independent Safety Testing

Tests the finished product for over 350 harmful substances — including pesticides, heavy metals, phthalates, and formaldehyde. Applies to every component of the tested product, not just one material. When granted at the factory level, it means the facility itself meets environmental and safety standards.

350+ harmful substances tested
Covers the entire product
Independent lab verification
Not an organic certification
~ Partial
CertiPUR-US
Foam-Only Certification

Certifies that certain harmful substances weren't used in the polyurethane foam only. Covers nothing else — flame barriers, adhesives, covers, and other components are out of scope. The foam itself still off-gases.

Low-VOC foam content
No formaldehyde in foam
Doesn't cover flame retardants
Foam itself still off-gases
~ Partial
Greenguard Gold
Low Emission Standard

Certifies VOC emissions fall below a threshold — not that the mattress is VOC-free. Doesn't address the materials themselves, only the level of off-gassing at a given point in time.

VOC emission thresholds met
Stricter than basic Greenguard
VOCs still present
Doesn't restrict materials
✗ Ignore
"Natural" / "Eco"
Marketing Language — Not a Certification

No regulatory definition on mattress labels. A mattress can legally call itself "natural," "plant-based," or "eco-friendly" while containing polyurethane, chemical flame retardants, and fiberglass.

No regulatory definition
No third-party verification
No material restrictions
Often masks foam content
Section 03 — Before You Buy

10 questions to ask any mattress brand

Before committing to any mattress — even one with certifications — ask these questions. How a brand responds tells you as much as the answer itself. Check them off as you research.

Your pre-purchase due diligence checklist.

Click each question as you verify it. A brand that's transparent will answer every one of these directly and without hesitation.

If a brand can't clearly answer these, that itself is a significant red flag — regardless of what certifications they display.
What specific flame retardant do you use? Wool, PLA, or Kevlar are acceptable alternatives. "Meets all federal regulations" without specifics is not an answer — manufacturers aren't required to disclose this. ✓ Acceptable: Organic wool barrier, PLA fiber
Does the mattress contain polyurethane or memory foam? Any amount of polyurethane foam is a source of VOC off-gassing and microplastic shedding over time. ✓ Acceptable: Natural latex, innerspring, organic fiber
Is the latex 100% natural and GOLS certified? "Latex" can mean 100% natural, synthetic, or blended. Only GOLS-certified 100% natural latex is a clean option. ⚠ Watch for: "Natural latex" without GOLS = likely a blend
Does the cover or any layer contain fiberglass? Fiberglass is used in many budget and mid-range mattresses. It's safe when sealed, but catastrophic if the cover is ever removed. Ask directly: "Does any component of this mattress contain fiberglass?"
Has this mattress been independently tested for VOC emissions? Third-party lab testing is the only reliable measure. Ask for the test results, not just a certification name. ✓ Best case: Test documentation on request
What adhesive is used to bond layers together? Adhesives are a frequently overlooked VOC source. Many foam mattresses use petroleum-based glues that off-gas independently. ✓ Acceptable: Water-based adhesives or mechanical assembly
Is your waterproofing or stain resistance PFAS-free? If they advertise stain or water resistance without explaining how, PFAS is the likely answer. ✓ Acceptable: Organic wool provides natural moisture-wicking
What certifications do you hold, and what exactly do they cover? CertiPUR-US only covers foam. GOTS only covers textiles. Ask what each certification actually applies to. ✓ Gold standard: GOTS + GOLS + MADE SAFE across all components
Where is the mattress manufactured? Countries with looser regulations may use flame retardants banned in the U.S. The EWG specifically flags imported products — China has no PBDE restrictions at all. ✓ Preferred: U.S. or E.U. manufactured with full traceability
Can I get a complete layer-by-layer material list? The most confident brands publish full material disclosure and will confirm everything in writing. Hesitation here is a significant red flag. ✓ Best brands: Full ingredient transparency on their website
Section 04 — Red Flags

Marketing phrases that should give you pause

The mattress industry has become expert at language that sounds clean without committing to anything. These are the most common phrases — and what they actually mean.

⚑ Red Flag
"Plant-based foam"

Still polyurethane foam — just with 5–20% soy or castor oil substituted in. The majority is still petroleum-derived, still off-gases VOCs, and still requires chemical flame retardant treatment.

⚑ Red Flag
"Natural latex"

Without GOLS certification, this frequently means synthetic or blended rubber. Synthetic latex is petroleum-derived styrene-butadiene. Confirm GOLS and 100% natural sourcing before trusting this label.

⚑ Red Flag
"Meets all safety standards"

A 2025 study found a compliance-labeled mattress containing 1,800 ppm of an EPA-banned flame retardant. Compliance means it passed a burn test — not that its ingredients are safe for long-term human exposure.

⚑ Red Flag
"Stain resistant" / "Waterproof"

Without explanation, these features almost always mean PFAS treatment — the bioaccumulative "forever chemicals." Natural wool alternatives exist but are rarely what conventional brands use.

⚑ Red Flag
"CertiPUR-US certified"

Commonly overstated. CertiPUR-US only certifies the polyurethane foam — not covers, flame barriers, or adhesives. A mattress can be CertiPUR certified and still contain fiberglass or chemical flame retardants.

⚑ Red Flag
"Non-toxic" / "Low VOC"

"Non-toxic" has no regulatory definition for mattresses and requires no certification. "Low VOC" without a specific test result is equally meaningless. Ask for actual emission data from a third-party lab.

Section 05 — The Ideal Profile

What a genuinely clean mattress looks like

Every component matters. Here's the complete profile of a clean mattress — what it's made of, how it handles fire safety, what certifications it should carry, and what it must never contain.

The Clean Mattress Profile

Core Support
100% Natural Latex (GOLS certified) or pocketed steel coils. No polyurethane foam in any layer — not even a thin comfort layer.
Comfort Layers
Organic wool and/or organic cotton — both GOTS certified. No synthetic fiber fill, no polyester batting, no blended materials.
Fire Safety
Organic wool barrier (most natural) or PLA fiber. No chemical flame retardants of any type, no fiberglass under any circumstances.
Cover / Ticking
GOTS-certified organic cotton or organic wool. No vinyl, no PVC, no synthetic blends. Unbleached where possible.
Adhesives
Water-based, non-VOC adhesives — or no adhesive at all. Layers held mechanically or by natural tension.
Waterproofing
If needed: organic wool or PLA only. No PFAS, no PVC coating, no vinyl encasement of any kind.
Manufacturing
U.S. or E.U. manufactured with full material traceability. Third-party tested, not self-certified.
Transparency
Full layer-by-layer material disclosure published on their website. Willing to confirm all components in writing.
Section 06 — The Brands We Carry

Two answers to the same question.

We evaluated every brand against the criteria on this page before carrying them. Naturepedic and Aireloom by Kluft represent two distinct paths — one is the most certified organic mattress in America, the other is 80+ years of luxury artisan craftsmanship with premium natural materials. Here's how they each hold up.

✦ Luxury Artisan Craftsmanship
Aireloom by Kluft
80 years of handmade California luxury.
Founded 1940 by King Karpen · Handcrafted in California · Acquired by E.S. Kluft & Co. 2004

Aireloom occupies a different position on the spectrum: not the most certified brand in the industry, but one of the most enduring names in luxury handcrafted sleep. Their Karpen Natural and Karpen Luxury collections are built around layers of natural latex, Joma wool, cashmere, silk, and alpaca — premium natural materials that don't appear in most mattresses at any price. The story is craftsmanship, heritage, and sensory luxury. The certifications are more limited, and we believe in being honest about that.

Buying Guide Criteria — How Aireloom Performs
Core material (Karpen collections)
TerraPur™ natural Talalay latex in Karpen Natural and Luxury lines. No memory foam in these collections.
Luxury natural fibers
Joma wool, cashmere, silk, horsehair, alpaca — exceptional natural comfort materials used throughout their premium lines.
