What Are Mattress Flame Retardants and Are They Safe?

Introduction

Mattress flame retardants are chemicals or materials added to mattresses to slow the spread of fire—but are they truly safe for your health? That’s a question more people are asking as awareness grows about what’s inside the products we sleep on every night.

Did you know that U.S. federal regulations require all mattresses to withstand an open flame for at least 30 minutes? This safety standard, though life-saving in theory, led manufacturers to infuse flame retardants into mattress designs—some of which have come under scrutiny for potential health risks. Over the past decade, a growing body of research has linked certain chemical flame retardants to health concerns ranging from respiratory issues to hormone disruption.

What Are Mattress Flame Retardants?

Mattress flame retardants are materials or chemicals added to mattresses to prevent or slow the spread of fire. They’re required by law in many countries to meet flammability standards, ensuring that a mattress won’t become a deadly fire hazard in the event of an accident.

 Types of Mattress Flame Retardants

Flame retardants generally fall into three main categories:

• Chemical Flame Retardants
  • Examples: PBDEs (polybrominated diphenyl ethers), TDCPP, TCEP
  • Function: Chemically disrupt the combustion process.
  • Risks: Some are linked to hormone disruption, developmental issues, and cancer.
• Inherent (Non-Added) Flame Retardants
  • These are built into the mattress materials during manufacturing.
  • Examples: Polymeric compounds that resist ignition without off-gassing toxins.
• Natural Flame Barriers
  • Examples: Wool, thistle fiber, and silica-based rayon
  • Advantages: Non-toxic and naturally flame-resistant.

 How Do They Work?

Flame retardants operate by:

• Interrupting the combustion process
• Forming a protective char layer on the material surface
• Reducing oxygen availability near the ignition site

 Why Are They Used in Mattresses?

• To comply with federal fire safety laws like California TB117-2013 and 16 CFR Part 1633.
• To give consumers more time to escape during a fire.
• To protect against open flame accidents caused by lighters, candles, or faulty wiring.

 Common Mattress Layers That May Contain Flame Retardants:

• Foam cores (especially polyurethane)
• Quilted top layers
• Fire sock barriers (e.g., fiberglass or silica blends)

Are Chemical Flame Retardants Safe?

The safety of chemical flame retardants has become a hot-button issue—and for good reason. While these additives help mattresses pass flammability tests, research increasingly shows they may pose serious health risks, especially with long-term exposure.

Potential Health Risks of Chemical Flame Retardants

Some chemical flame retardants have been linked to a range of health issues, including:

• Endocrine Disruption
  • Chemicals like PBDEs and TCPP can mimic or interfere with hormones.
• Neurological Effects
  • Studies suggest exposure may affect brain development in infants and young children.
• Respiratory Problems
  • Off-gassing chemicals can irritate lungs, especially in asthma sufferers.
• Cancer Risk
  • Some, like TDCPP, are classified as possible human carcinogens by the EPA and other regulatory bodies.
• Reproductive Toxicity
  • Certain compounds may impact fertility or fetal development.

 Who’s Most at Risk?

• Infants and toddlers: Spend more time sleeping and are closer to mattress surfaces.
• Pregnant women: Increased sensitivity to endocrine-disrupting chemicals.
• People with respiratory conditions: More prone to irritation from off-gassed chemicals.

 Where Chemical Flame Retardants Hide

• Polyurethane foams
• Adhesives
• Outer fabrics
• Fire sock layers

 Banned or Phased-Out Chemicals

Several dangerous flame retardants have been banned or phased out in the U.S. and EU, including:

• PBDEs – banned in many states and discontinued in manufacturing
• Tris (TDCPP, TCEP) – restricted in children’s products and mattresses

 What to Look for Instead

• Mattresses labeled “free from chemical flame retardants”
• Certifications such as:
  • GREENGUARD Gold
