16 CFR 1633 Labels: Overview & Common Mistakes

Jun 13th, 2025 Uncategorized

If you sell mattresses, you know how strict federal regulations can be around flammability. Here's a quick refresher on 16 CFR 1633 flammability labels, and common mistakes that could make your mattress noncompliant.

What is a 16 CFR 1633 Label?

16 CFR 1633 labels are federal flammability labels for mattresses. They are mandatory for all mattresses, because the federal government requires every mattress to be put through a government-approved flammability test.

A 16 CFR 1633 label certifies that a mattress has passed flammability testing by an independent third-party laboratory.

Common Mistakes

Making these common errors can make your 16 CFR 1633 label noncompliant, and open you up to costly fines and violations.

  • Wrong Formatting — Label formatting guidelines are strict, and require specific font sizes, text box sizes, and text justification.
  • Missing Foundation Intention — You must disclose whether the mattress is intended to be used with, without, or both with and without a foundation. You must also provide a foundation ID if it is intended to be used with a foundation.
  • Missing Model Number or Prototype ID — Many customers leave this information blank. You must list the Model Number or Prototype ID for your label to be compliant.
  • Other Missing Information — Your 16 CFR 1633 label needs complete information, like the manufacturer's name, even if it appears on another label. This is because law labels are regulated by the state, and 16 CFR 1633 labels are regulated at the federal government.
