Thick, cushy, 100% wool carpet pad made in the USA - 36 oz Our thick, luxurious carpet cushion surpasses all expectations. Unlike carpet padding made from petroleum-based urethane, synthetic latex, or questionable post-consumer content, these unique cushions are made from 50% pure virgin wool and 50% post-industrial recycled wool yarn. They're 100% natural and made in the USA. These rolls are 22.5' long, 6' wide and 3/8" thick (135 Square Feet). The 3/8 inch thickness provides a cushy feel that's long-lasting and won't let you down, literally. That's because wool has a superb memory, and it's also cushier than a hair/jute pad. A good carpet cushion can add to the useful life of a carpet. It can also improve the acoustical and thermal properties and reduce the overall maintenance costs. TIP: For area rugs, use our Rug Gripper underneath this pad. [tabs] Why We Like It You have to feel this pad to believe it.
