  "question": "Which crib mattress covers are listed as made without harsh chemicals?",
  "answer": "None of the checked facts says these covers are made without harsh chemicals, so the materials each cover is listed with are shown instead. Naturepedic Breathable Ultra Crib Mattress Cover: The cover/pad is quilted with a 100% organic cotton fiber face over a breathable mesh layer and a 100% polyester backing. Breathable airflow construction allows air through the sleep surface; dissipates heat and moisture; organic cotton sleep surface; allergen-friendly materials. Naturepedic Breathable Crib Mattress Cover: The cover's top layer is organic cotton and the bottom layer is polyester. Waterproofing is a TPU polyurethane barrier. Naturepedic PC46 (standard crib) / PC46-MN (mini crib): Top fabric is organic cotton and the bottom fabric is polyester. The store page lists the waterproofing as a TPU polyurethane barrier.",
