Designed with an ergonomic curve to provide adequate support for your head, neck, and shoulders, these pillows are crafted to help you fall asleep quickly and enjoy a comfortable night's rest, catering to side, stomach, back, and all preferred sleeping positions. Upon opening the vacuum-sealed bag, the pillows begin to fluff, offering instant comfort. Additionally, the machine-washable feature saves time and effort, allowing for year-round softness and prevention of pilling when washed in a gentle cycle with cold water. They can be sun-dried or tumble dried on low as needed.
