Why Choose Upholstery Foam 70 ILD?

When a cushion needs to hold its shape under real, everyday use, upholstery foam 70 ILD is one of the firmest options you can choose. It is a strong pick for seats that get sat on hard and often, and for projects where sagging simply isn't an option.

What ILD Means

ILD, or indentation load deflection, measures how much force it takes to compress foam. The higher the number, the firmer it feels. A rating around 70 falls into the extra-firm range, so this foam pushes back and keeps you supported instead of letting you sink in.

Best Uses for Extra-Firm Foam

• Dining chair and bench seats
• Window seats and banquettes
• Boat, RV and patio seating
• Headboards and firm cushion bases

What to Look For

Pay attention to density as well as firmness, since high density cushion foam generally lasts longer. Choose a thickness that suits your frame, and consider a soft topper or batting if you want a gentler feel on top of firm support.
