upholstery foam tb 117

If you are rebuilding a sofa, recovering dining chairs or cutting new seat cushions, upholstery foam TB 117 labeling is worth understanding before you buy. TB 117 refers to California Technical Bulletin 117, a flammability standard for upholstered furniture that many manufacturers and makers use as a benchmark for fire-safe cushioning.

What TB 117 Means for Furniture Foam

The original TB 117 focused on how filling materials like foam respond to a small open flame. The updated TB 117-2013 shifted the emphasis to smolder resistance, the kind of slow burn a dropped cigarette can cause, and looks at cover fabrics, barrier materials and fillings. Always check a product's listing or label to see which version, if any, it references.

How to Choose the Right Cushion Foam

Match Firmness to the Seat

Firmer foam suits dining chairs, benches and bench-style seating, while softer foam works well for backs and lounge cushions.

Consider Thickness and Use

• Thicker foam for sofa seats and deep cushions
• Thinner foam for headboards and chair pads
• Wrapping with batting for a smoother, fuller look
