NuFoam is a foam alternative made from densified polyester, cut here as a 56 × 56 × 5 cm (22 × 22 × 2 in) cushion insert. It resists mildew and won’t yellow or crumble, making it useful for chair cushions, patio covers, and RV projects. Expect some compression with frequent sitting, so plan a snug cover fit and hand wash then air dry, It’s a great choice for gifting, seasonal covers, and everyday home projects.
