Kelsea Ballerini's Must Haves: From a Pilates Machine to a Louis Vuitton Duffel Bag

As she's grown up (and encountered plenty of sleepless nights), Ballerini has discovered the importance of creating a solid sleeping routine — which now involves having this Dosaze Contoured Orthopedic Pillow ($120) in her bed at all times. "This is 30," Ballerini jokes. "She is orthopedic. She is gorgeous, and she gets the job done. My neck has never felt better. I love it."

Pro Tip: While this particular pillow is designed with orthopedic benefits in mind, Dosaze also offers a number of other pillow types that range from a therapeutic wedge pillow to an adjustable, foam-filled pillow.
