Unprotected mattresses create the perfect breeding ground for bacteria and dust mites, a major exacerbating cause of eczema and allergies. Protect your little one and their mattress with the Living Textiles Smart-Dri mattress protector - the smart choice for every parent. Smart Dri helps create a healthy sleeping zone for your little one. Features: 1: Ingenious Smart-Tex bonded waterproof cotton layer provides maximum mattress breathability to help reduce the risk of allergens, and it stops that rustling noise that plastic covers make! 2: Adsorbent inner wadding draws moisture away from the baby to help prevent rash and provides additional padding for a comfortable sleep.
