Farifield-Poly-Fil NuFoam. Poly-Fil NuFoam is a safe alternative to conventional foam that is made from densified polyester batting. It is mildew resistant, and won’t yellow or disintegrate. It’s perfect for chair cushions, deck furniture, camping, futons, crib bumpers, playpen mats, recreational vehicle accessories and more. Made from compressed layers of 100% polyester that range from one to four inches thick. NuFoam works best for occasional seating as it will compress over time. We recommend using NuFoam that is one inch thicker than your intended cushion to allow for compression. It will be a snug fit inside the cover. Resists mildew. Non-allergenic. Unconditionally guaranteed. Care: Hand wash, air dry. Packaging graphics subject to change. Made in USA.
