Flame Codes at the Banquette: What Governs Restaurant Seating Fabric
Upholstered seating in a public dining room is regulated for fire. The relevant tests are cigarette-ignition standards, not the drapery flame tests people often assume apply.
The most common fire-code mistake in a restaurant fabric spec is applying the wrong test to the seat. Sorting the myths from the standards keeps a banquette out of trouble.
Myth: the vertical flame test that governs curtains also covers seating. Fact: upholstered seating in a public space is regulated mainly for how it responds to a smoldering source such as a dropped cigarette. The references are NFPA 260 and NFPA 261, which assess the cigarette-ignition resistance of the fabric-and-filling assembly, and California Technical Bulletin 117-2013.
Myth: TB 117 still requires open-flame-resistant foam. Fact: the 2013 rewrite dropped the pre-2013 open-flame foam requirement and tests the cover fabric's resistance to smoldering ignition instead, a change that shifted which materials pass. TB 117-2013 became the national benchmark after California adopted it, but it binds only where the authority having jurisdiction adopts it, so confirm the standard your jurisdiction actually enforces.
Myth: NFPA 701 is irrelevant to a restaurant. Fact: NFPA 701 is the vertical flame test that governs anything that hangs. Curtains, fabric room dividers, and large stretched hanging panels must pass it, and confusing it with the seating standard is expensive both ways: a drapery-weight fabric can be wrong on a banquette, and a seating fabric hung as a curtain can fail 701 outright.
Myth: the mill's word is enough. Fact: a dining room is a place of public assembly, and the fire marshal can demand documentation before an occupancy permit issues. Keep the manufacturer's certification of the exact test the fabric passed, tied to the assembly it was tested in, since a cover fabric's smolder behavior depends partly on the filling behind it.
The rule that survives all four: smolder standards for anything sat on, NFPA 701 for anything that hangs, written certification for both, in the file, before goods ship.
