TB 117-2013, the latest CAL-117 Tech Bulletin, is a flammability standard for upholstered furniture. It mandates that, beginning January 1, 2015, all filling materials (ie. foam) in California must meet the smolder-resistant requirements of the TB 117-2013 Resilient Filling Material Test. This tests the flammability resistance of the inner materials.
All Via Seating product manufactured with Via Seating in-stock fabrics meet the requirements of CAL-117.
COM fabrics are not guaranteed to pass CAL-117. Please contact the COM supplier directly to determine the flame-retardant nature of any COM supplied to Via Seating.
Effective January 22, 2019, the State of California repealed TB133. The only place TB133 is required is in Boston “un-sprinkled” buildings.
Via Seating chairs, unless otherwise specified, do not meet TB133. Most Via Seating chair models can be prepared to meet the flame-retardant requirements of the Boston Fire Code. In order to comply with these fire codes, Via Seating must upholster the chair with a flame-retardant material (i.e. Kevlar® or equivalent). Additionally, most plastic components (i.e. seat pan, back shell, shrouds, etc.) must be either removed or completely upholstered with a flame-retardant material.
Please note, any chair models specified to comply with TB133 may not resemble what has been photographed and shown in marketing materials. Via Seating is not responsible for determining the requirement of TB-133 compliance. Check with your local building departments to determine if TB133 is required on your order. To specify TB133 on Via Seating chairs, please refer to the optional COM/COL add on found by the TB133 option per series in their pricing pages within the price book, when applicable.
Additional COM/COL is required for TB133. Please send in COM/COL requirements for seat/back cushions and the back shell.
