Taylor Swift's Eras Tour pillow is 20% off for Prime Day

Taylor Swift showed a behind-the-scenes snap from the Eras Tour on "The Late Night Show with Stephen Colbert" this fall, featuring her cat Benjamin Button asleep on her head and the Coop Original Adjustable Pillow, which is 20% off on Amazon for Prime Day. Swift quipped, "This is my youngest, his name is Benjamin Button, and he is really attached to my pillow, wherever that may be — in whatever country that is.

They travel with me everywhere." The Coop pillow carries a 4.5-star average from over 65,900 Amazon reviews. One particularly satisfied shopper wrote, "I really think this pillow might be the last pillow I ever need," adding, "I liked it so much I bought another one immediately." The brand says the adjustable design suits back-, stomach- and side-sleepers; users can remove or add the proprietary "Oomph" filling to change firmness.

Other celebrity-loved bedding is discounted for Prime Day, including Cozy Earth’s Bamboo Sheet Set, which Oprah once called the "softest ever" on her "Favorite Things" list.
