CAL TB117-2013 seating includes upholstered office chairs, conference chairs and lounge furniture. California Technical Bulletin 117-2013 describes tests for the resistance of upholstered-furniture components to smouldering ignition under specified conditions. The claim can inform a furniture brief, but it does not mean a chair is fireproof or that it has passed every flame-based test.
Understand the test’s focus
TB117-2013 concerns smouldering ignition, including tests on cover fabrics, barrier materials, resilient filling and decking where applicable. The standard uses defined laboratory methods. A result for one component or assembly should be checked against the actual materials in the finished chair. It is not a general statement about all possible ignition sources. The different component tests are intended to examine how a cover, barrier or filling behaves in the stated smoulder scenario. A project team should note which part was tested and how it relates to the furniture actually delivered, rather than collecting a test name without context.
For CAL TB117-2013 seating, ask for the relevant test or compliance evidence on the specified model and upholstery. A different fabric, foam or interliner can change the construction. Keep the material codes and document reference together so the final supplied version can be verified.
Fit the task chair to its desk
An upholstered swivel chair should be selected for the person using it and the desk where it will stand. Compare seat and back support, adjustments and armrests. The base needs room to move, and the user must be able to reach equipment without twisting around a cabinet or cable bundle.
CAL TB117-2013 seating can include several office-chair forms with different padding or upholstery. The smouldering test result is not a substitute for evaluating those seating functions. A chair with a headrest may offer a different sitting position from a low-back chair, while a mesh-and-upholstery combination brings its own material specification. Both need to be judged at the intended desk. If a shared workstation serves several people, consider how easily the chair settings can be changed between users.
Arrange conference chairs around the table
Meeting chairs may have four-leg, cantilever or swivel bases. Their movement affects how people enter a room, face one another and turn toward a display. Check armrest clearance under the table and the route behind occupied chairs. A dense row can feel comfortable when empty but crowded once participants arrive. Mark the pulled-out chair positions on the plan and check access to doors and shared equipment. The table should still be usable by people at its ends.
Within CAL TB117-2013 seating, upholstered conference chairs can give a room a softer material palette. Verify that the chosen cover and filling are included in the documented version. A visually similar chair with another upholstery grade may require separate evidence.
Give lounge furniture a considered place
Upholstered sofas and armchairs can create a waiting or informal discussion point. Position them so people can converse without blocking a corridor. A low table may help if visitors need a place for a notebook or drink. Consider how much space the group occupies when every seat is in use. People may stand beside the seating to greet one another, so leave that space outside the main path as well.
Modular sofa elements deserve particular attention. A corner or end module may have a different construction from a simple seat, and the final arrangement needs clear access. Confirm the fire information for the selected pieces and upholstery rather than relying on the name of the overall range.
Keep other fire requirements distinct
TB117-2013 is a smouldering-focused standard. A project may also call for a different ignition source, a local furniture classification or a room-level fire strategy. Those requirements should be stated separately. Passing one test does not demonstrate that every other requirement has been met.
CAL TB117-2013 seating can be specified accurately when the material evidence matches the chosen chair or sofa. First select furniture that suits the user and room. Then confirm the relevant smouldering-ignition information for the exact assembly and keep it with the final schedule.
