I'm a pillow refugee. I'm selling this because it didn't suit me. In my subjective opinion, there's no sagging. I think it's clean, but since it's a used item, please refrain from returns or exchanges. Please do not swap the product. I am also selling another of the same item. It's not a mistake. Navy AiR pillow, designed to support comfortable sleep. - Color: Navy - Brand: AiR - Website: www.airweb.jp Thank you for looking.
