upholstery foam 25 ild

If you want cushions that feel plush without collapsing, upholstery foam 25 ILD is one of the most versatile choices for home projects. Its soft-to-medium feel gives comfortable give while still holding its shape, making it a favorite for back cushions, headboards, and padded accents.

What 25 ILD Means

ILD stands for indentation load deflection, a measure of how many pounds of force it takes to compress foam by 25% of its thickness. A lower number feels softer. At 25, the foam sits in a comfortable middle ground that is softer than typical seat foam but more supportive than ultra-plush options.

Best Uses for Soft Upholstery Foam

• Sofa and chair back cushions
• Padded headboards and wall panels
• Throw pillows and bolsters
• Light-use seating such as accent benches

What to Look For

Firmness is only half the story. Check foam density too, since higher density upholstery foam generally lasts longer under regular use. Measure your cushion covers carefully, and consider adding a layer of batting for a smoother, fuller look under fabric.
