What a Prop 65 warning on a cushion does and doesn't tell you
Pull up a chair. A chemical warning on a cushion tag has sent more than one family to the porch rail with a worried question, and the honest answer is shorter, and more useful, than the internet makes it sound.
SaveThe quick answer
A Prop 65 warning on a cushion means the business says the product can expose you to a chemical on California's Proposition 65 list; it does not mean the cushion is banned or proven harmful at that level. A missing warning isn't a certificate either, because businesses with fewer than 10 employees don't have to warn. Ask the maker for named materials and checkable certificates.
The question families ask at the porch rail
A Prop 65 warning is a notice, not a verdict. I say that first because the people who bring me a Prop 65 cushion question are rarely casual shoppers. They're parents with a new baby, somebody with a chemical sensitivity, a grandmother buying a floor cushion for the grandkids' sleepovers. They've seen the warning on other things in the house, and now they want to know what it means on the thing they'll sit on.
It has a real answer. It's just not the one-word answer anybody wants. Chemical questions are a small, earnest thread: flame retardants, off-gassing, PFAS, certificates and, now and then, the California warning by name. They come up for a living room floor sofa as often as for a kids' room corner cushion. Here's how I read that warning, what it leaves out, and what to ask a maker instead.
What the warning says, and three things it doesn't
Proposition 65 is California's right-to-know law. Businesses with 10 or more employees must give a clear warning before they expose people to a chemical on the state's list, and there is a furniture version of the warning that sends you to P65Warnings.ca.gov/furniture, run by the state program. The chemicals the state names for furniture include certain flame retardants (antimony trioxide, chlorinated tris or TDCPP, TBBPA and TCEP), phthalates in vinyl upholstery, and PFOA and PFOS in some older stain-resistant upholstery.
Here's what the warning does not tell you:
- It isn't a ban. Prop 65 requires the notice; it doesn't take the product off the shelf.
- It isn't a measurement. A business can skip the warning when exposure stays below the level the state sets for that chemical, the safe-harbor level. The state program also explains that a business may warn simply because it knows a listed chemical is present, without measuring anything. So the label alone won't tell you how much, or whether any limit was crossed.
- Its absence isn't a certificate. Businesses with fewer than 10 employees aren't required to warn, so a small maker's cushion can carry no warning without anybody having tested anything.
A warning is a flag to ask a better question. It is not, by itself, the answer.
Five labels a cushion can carry, side by side
| Label or claim | Who stands behind it | What it covers | What it doesn't prove |
|---|---|---|---|
| Prop 65 warning | The business selling it, under California law | Possible exposure to a chemical on the state list | That the product is banned, or how much exposure there is |
| Flame-retardant checkbox (SB 1019) | The maker of covered furniture sold in California | Whether flame-retardant chemicals were added, on furniture made from January 1, 2015 | Anything about other chemicals |
| Law label, 'Under penalty of law…' | A maker licensed by California's Bureau of Household Goods and Services | Who made it and the license number; Type No. 1, at least 2 x 3 in, is the label for chair cushions and decorator pillows | Anything about chemicals |
| OEKO-TEX Standard 100 | A fabric mill, certified for its own scope and renewed every year | Textiles tested against a list of 1,000+ harmful substances | Fire behavior, durability, or that the finished cushion is certified |
| CertiPUR-US | A foam producer listed in the program's public directory | Flexible polyurethane foam only, tested for content, emissions and durability | The cover fabric, or any brand that isn't in the directory |
How to read a cushion's warning, step by step
Find every label, not just the loud one
Look at the hang tag, the sewn-in law label and the packaging, and read the listing before you buy. On covered upholstered furniture sold in California you may also find the flame-retardant statement with its checkbox. One label is a sentence; all of them together tell the story.
Look for a named chemical
For products made from January 1, 2028, even the short-form warning, the brief version on small tags, must name at least one listed chemical. Tags made earlier may name none. No name? Write that down as your first question for the maker.
Match the chemical to the part
The state's furniture list points at particular parts. Flame retardants belong to foam and treated fabric. Phthalates show up in vinyl upholstery. PFOA and PFOS turn up in some older stain-resistant finishes. Knowing the part tells you which question to ask: foam, cover or finish.
Read the state's own furniture page
Go to P65Warnings.ca.gov/furniture, the state program's page for furniture warnings, and read it before any forum thread, including the ones that start with a cousin's opinion.
Ask the maker named, checkable questions
Skip the yes-or-no question every seller answers with yes. Ask instead: What is the foam, by type and density? Were flame-retardant chemicals added to the foam or the fabric? What is the fiber content of this exact fabric code? Which certificates cover it, whose are they, and what are the numbers? Get the answers in writing.
Check whose certificate it is
An OEKO-TEX Standard 100 number belongs to a mill and covers that mill's own scope; it runs for a year and keeps its number on renewal. Enter it on OEKO-TEX's official label check, where the holder, scope and validity are listed. A CertiPUR-US claim should match a producer in that program's public directory.
Weigh it for your household
If someone at home has sensitivities or allergies, ask what the filling is made of and for a photo of it, and ask about natural-fiber covers such as cotton. The natural-fiber cushion guide goes further. Then decide with facts on the table, not one line on a tag.

Key facts
- Proposition 65 requires businesses with 10 or more employees to warn before exposing people to chemicals on California's list.
- A Prop 65 warning is a disclosure, not a ban, and a missing warning is not a safety certificate.
- California's furniture warning points to P65Warnings.ca.gov/furniture.
- For products made from January 1, 2028, short-form warnings must name at least one listed chemical.
- OEKO-TEX Standard 100 tests textiles for harmful substances but says nothing about how a fabric burns.
- The workshop's standard seat foam is ordinary 32-density polyurethane, about 2.0 lb/ft³, with no added flame retardants.
- The workshop's foam cushions are declared as roughly 60% polyurethane foam and 40% upholstery fabric, a named-materials answer worth asking any maker for.
The California rules that sit beside Prop 65
Prop 65 isn't the only California rule a cushion can meet. TB 117-2013 is a smolder test, with a lit cigarette, for cover fabric, filling and barrier, and it neither requires nor bans flame-retardant chemicals. Since January 1, 2020, AB 2998 has capped designated flame-retardant chemicals at 1,000 ppm in new upholstered furniture, juvenile products and mattresses sold in the state, and the same limit applies to replacement parts used by custom upholsterers. For stain and water finishes, AB 1817 bans regulated PFAS in upholstery and furnishings at 100 ppm total organic fluorine from 2025, dropping to 50 ppm in 2027.
Furnishing a house out west? The California cushions page gathers the room and climate notes. For the fire side, read flame-retardant-free cushions; for certificates, OEKO-TEX Standard 100 for cushions and CertiPUR-US foam explained. Off-gassing and new-foam smell have their own page: airing a new foam cushion.
Common mistakes when reading chemical labels
- Reading a warning as a recall. Prop 65 requires the notice; it doesn't pull the product.
- Reading no warning as a clean bill of health. Businesses with fewer than 10 employees don't have to warn at all.
- Treating OEKO-TEX as a fire or quality rating. The standard itself says it isn't a quality label, and it says nothing about how a fabric burns.
- Taking a certificate on faith. Ask whose it is and check the number; a mill's certificate covers that mill's fabrics, not a whole cushion.
- Assuming 'linen' means natural fiber. Many linen ranges are a polyester linen-look that melts under a hot iron, so ask the fiber content of the exact code.
- Not asking about the filling. Tufted cushions are often filled with polyester hollow-fiber clusters, sometimes called silicone balls, which are neither beads nor foam.
- Trusting an adjective over a number. A certificate number you can check tells you more than any one-word promise on a listing.
The writing corner and the two corduroy poufs
A buyer in the US wrote to the workshop wanting seating for a writing corner that kept chemicals to a minimum. She did her homework the right way. Before she ordered a green and a blue corduroy pouf sofa, she confirmed the fabric's OEKO-TEX certification and asked what the filling was, and was told latex foam.
Then real life arrived. The vacuum packing was so tight that opening the bags caused some damage. The green pouf puffed up; the blue one stayed hollow in places. And the backrest was simply too short for sitting upright to write.
Every chemical question she asked got a straight answer, and none of them turned out to be the problem. The problems were a tape-measure question and an unpacking question. So ask about the materials, neighbor, absolutely. Ask about the back height and the angle too. A lounge pouf isn't a desk chair, whatever it's made of.
A Prop 65 warning on a cushion is a disclosure, not a ban; ask which chemical the warning names and which part carries it: foam, cover or finish.

Buyer questions: chemicals, labels and certificates
- A common question
Are your fabrics OEKO-TEX certified, and would the cushion need a California Prop 65 warning?
The workshop's answerAsked about flame retardants and a Prop 65 warning together, the workshop pointed to its fabric certification: the fabrics come from a mill certified to OEKO-TEX Standard 100 (03.T.3239), and the certificate is shared on request. Its number can be checked on the official OEKO-TEX website, where the holder, scope and validity are listed. Keep in mind that a fabric certificate answers a different question from a Prop 65 warning: it covers the textile, not the foam or the finished cushion.
- A common question
Does your foam carry CertiPUR-US certification?
The workshop's answerAsked directly, the workshop described the foam, a high-density polyurethane seat foam, and did not claim CertiPUR-US certification. Its fabrics come from a mill certified to OEKO-TEX Standard 100 (03.T.3239), and documents are shared on request. If a specific certificate matters to you, ask for the document itself before you order.
- A common question
Do you treat the fabrics with flame retardants or any other finish?
The workshop's answerThe workshop's written answer was that its fabrics are not given a flame-retardant finish and that there is no fiberglass in its products. For buyers with strict requirements, pieces can also be made in a special fabric from the catalog, such as a cotton option. Treat any answer like this as the maker's statement, and ask about the exact fabric code you're buying.
- A common question
What kind of foam is inside, and was anything added to it for fire?
The workshop's answerThe standard inside is high-density polyurethane upholstery foam, and the workshop has told buyers that no flame-retardant additives are put into it. Not every product uses the same filling, though: one reply described a corduroy pouf's filling as natural latex upholstery foam. If allergies or off-gassing worry you, ask which filling your specific piece uses.
- A common question
What's actually inside the tufted cushions?
The workshop's answerPolyester hollow fiber rolled into small clusters, often called silicone balls, which feel soft like cotton rather than springy like foam. The fill is packed densely, the standard mix often includes some cotton filler, and there's no foam core; the cushions are sewn by hand. The workshop can send a photo of the filling if you'd like to see it before ordering.
Prop 65 and cushions, briefly
Does a Prop 65 warning mean a cushion has been recalled?
No. Proposition 65 is a disclosure law: it requires businesses with 10 or more employees to warn about exposure to listed chemicals. It doesn't pull products from sale. Read a warning as a reason to ask the maker specific questions, not as a recall notice.
Why do some cushions carry no Prop 65 warning at all?
Several reasons. Businesses with fewer than 10 employees aren't required to warn, and a business can skip the warning when exposure stays under the state's safe-harbor level. The missing warning tells you about paperwork, not materials, so ask for fiber content, foam type and checkable certificates.
What changes on Prop 65 labels in 2028?
Amendments that took effect on January 1, 2025 set a three-year transition. For products made from January 1, 2028, the short-form warning, the brief version used on small tags and labels, must name at least one listed chemical, so buyers will see a chemical name even on small tags.
Is an OEKO-TEX label the same as a fire rating?
No. OEKO-TEX Standard 100 tests textiles against a list of more than 1,000 harmful substances, but the standard itself says it isn't a quality label and says nothing about burning behavior. Fire performance for upholstered furniture in California is a separate matter, covered by TB 117-2013.
What is the flame-retardant checkbox on California furniture labels?
Under SB 1019, covered furniture that must meet TB 117-2013 carries a statement with a checkbox saying the product either contains added flame-retardant chemicals or contains none. It applies to furniture made from January 1, 2015, and it's often the quickest written answer to the flame-retardant question.
