upholstery foam cal 117

Choosing upholstery foam cal 117 is a smart first step when you rebuild a sofa, pad a bench or make new seat cushions. Foam labeled Cal 117 is made to meet California Technical Bulletin 117, a flammability standard widely referenced for upholstered furniture. That makes it a common choice for both home projects and commercial seating.

What Cal 117 Means for Your Project

California TB 117 foam has been tested against a flammability standard for furniture filling materials. It is not fireproof, so pair it with suitable upholstery fabric and follow any local requirements that apply to your space.

How to Choose the Right Foam

Density and Firmness

Density and firmness work together to determine durability and feel. For everyday seating, look for:

• High density upholstery foam for sofa seats and dining chairs that get daily use
• Medium firmness for backs, headboards and cushions you lean against
• Softer foam for pillows, toppers and light-duty padding

Thickness and Fit

Measure your frame or old cushion carefully. Replacement cushion foam should fill the cover snugly, and a layer of batting can help round the edges.
