The chemical smell is terrible! The smell is similar to that of a damp, dirty, molding towel you found under a laundry pile. I followed there directions to allow 48 hours minimum before using. I left outside for 24 hours. I spritz Fabreze and tossed in my dryer on "Air" for several cycles. All to no avail. Need less to say, I do not use it! It can be found outside as a $40 dog pillow. What a terrible mistake. Why didn't you return it you ask? Have you read the conditions for return? Hah. I will never purchase a pillow ON-Line Ever!
