Federal Upholstered Furniture Flammability Rule Codified, Phasing Out Toxic Flame Retardants

A new federal standard replaces outdated open-flame tests with a modern smolder requirement for upholstered furniture. The shift eliminates the regulatory need for toxic chemical flame retardants, improving indoor air quality and protecting first responders.

At a glance

  • The federal government has codified 16 CFR Part 1640, establishing a national smolder-test standard for upholstered furniture.
  • The rule replaces an outdated 1975 open-flame test that forced manufacturers to use heavy doses of toxic chemical flame retardants.
  • Fire science shows that smolder tests better reflect real-world residential fires, which typically start with a dropped cigarette on fabric.
  • The phase-out of chemical flame retardants significantly reduces the release of cancer-causing furans and dioxins during house fires.
  • Consumers can verify compliance by checking for a permanent CPSC flammability label on the underside of new residential furniture.

You want a plush, comfortable sofa to sink into at the end of the day, but for decades, that comfort came with an invisible compromise. To protect your home from fire, manufacturers saturated the foam cushions inside your living room furniture with pounds of chemical flame retardants.[3]

It was a classic regulatory catch-22. Fire safety mandates demanded that furniture resist open flames, but the chemicals used to achieve that standard—such as organohalogens and organophosphates—were quietly migrating into household dust, linked by researchers to endocrine disruption and developmental issues.[3]

Now, that tension has been resolved. The federal government has codified the Safer Occupancy Furniture Flammability Act (SOFFA) into a national standard known as 16 CFR Part 1640.[1][2]

This landmark rule fundamentally changes how upholstered furniture is built and tested in the United States. By replacing an outdated open-flame test with a modern "smolder" standard, the law eliminates the regulatory pressure to use toxic flame retardants.[1][5]

The smolder test evaluates how assembled materials react to a dropped cigarette, replacing the outdated practice of holding an open flame directly to the interior foam.

To understand how we got here, you have to look back to 1975. That year, California implemented Technical Bulletin 117 (TB 117), a well-intentioned rule requiring the foam inside furniture to withstand a small open flame for 12 seconds.[3]

Because California is such a massive market, TB 117 became the de facto national standard. Furniture makers across North America began treating their polyurethane foam with heavy doses of chemical flame retardants to pass the test and sell their products nationwide.[3][4]

But fire science eventually revealed a critical flaw in the open-flame approach. In a real residential fire, the fabric covering the sofa ignites first. Once the fabric is burning, the resulting large flame quickly overwhelms the foam underneath, regardless of how many chemicals it contains.[3]

Furthermore, the health costs became impossible to ignore. Organizations like the Green Science Policy Institute demonstrated that these chemicals do not stay inside the cushions; they continuously migrate out of the furniture and into the air we breathe.[3]

Manufacturers can now meet federal fire safety standards using tightly woven fabrics and simple polyester barriers instead of chemical treatments.

Firefighters bore the brunt of this toxic legacy. When flame-retardant furniture burns, it releases highly toxic furans and dioxins. The International Association of Fire Fighters (IAFF) championed the new standard specifically to reduce their members' exposure to these cancer-causing byproducts during emergency responses.[2]

When flame-retardant furniture burns, it releases highly toxic furans and dioxins.

The breakthrough came when California updated its standard to TB 117-2013, shifting the focus from open flames to smoldering ignition sources, such as a dropped cigarette.[4]

A smolder test evaluates how the assembled materials—the fabric, the barrier, and the foam—react to a smoldering heat source. This aligns with how most real-world furniture fires actually start, providing a more accurate measure of safety.[1][5]

Crucially, manufacturers can pass a smolder test using tightly woven fabrics or simple polyester batting barriers, completely removing the need to inject the interior foam with chemical retardants.[3][5]

The International Association of Fire Fighters championed the new standard to reduce their members' exposure to cancer-causing toxins released by burning flame retardants.

The American Home Furnishings Alliance (AHFA) spent years lobbying to make this California standard the law of the land. They argued that a single, science-backed federal rule would prevent a confusing patchwork of state regulations while prioritizing consumer safety.[4]

Congress finally agreed, passing SOFFA and directing the Consumer Product Safety Commission (CPSC) to codify it. Today, under 16 CFR Part 1640, all residential upholstered furniture sold in the U.S. must meet this smolder-resistant baseline.[1][2]

For anyone designing a living room or shopping for a nursery, the impact is immediate and tangible. You no longer have to choose between fire safety and indoor air quality.[5]

When you flip over a new chair or sofa, you will now see a permanent label stating: "Complies with U.S. CPSC requirements for upholstered furniture flammability."[1][4]

Consumers can verify that their new furniture meets the modern smolder standard by checking for the mandatory CPSC compliance label.

While the federal rule does not explicitly ban flame retardants, it removes the test that made them necessary. Combined with state-level bans on specific chemicals, the industry has overwhelmingly shifted toward cleaner, chemical-free construction.[1][3]

It is a rare regulatory victory where everyone wins. Firefighters face fewer toxic fumes, manufacturers have a clear and achievable standard, and you get to breathe a little easier in your own home.[2][4][5]

Terms to know

Smolder Test
A flammability test that uses a smoldering heat source, like a lit cigarette, rather than an open flame to evaluate how materials react.
Flame Retardants
Chemicals added to manufacturing materials to slow the spread of fire, many of which have been linked to adverse health effects.
TB 117-2013
The updated California flammability standard that shifted focus to smolder resistance and serves as the basis for the new federal rule.
Organohalogens
A class of chemical flame retardants that can migrate into household dust and are associated with endocrine disruption.
16 CFR Part 1640
The federal regulation that codifies the smolder-test standard for all residential upholstered furniture sold in the United States.
