upholstery foam 13 ild

If you want cushions that feel plush and inviting, upholstery foam 13 ILD is one of the softest options to work with. ILD (Indentation Load Deflection) measures how much force it takes to compress foam, and a lower number means a gentler, more yielding feel. That makes 13 ILD foam a favorite for projects where comfort matters more than firm support.

Where Soft Upholstery Foam Shines

Because it gives easily under pressure, low ILD foam works best in places that cradle rather than carry weight:

• Back cushions on sofas, loveseats and chairs
• Pillow and bolster inserts for a relaxed, sink-in feel
• Padded headboards and wall panels
• Toppers layered over firmer seat foam

What to Look For

Thickness and Use

Choose a thickness that matches your frame and the loft you want. For seats that get daily use, consider pairing soft foam with a firmer base layer.

Density and Wrapping

Check the listed density for durability, and plan on wrapping foam in batting to round edges and help your upholstery fabric fit smoothly.
