A body pillow is a long, rectangular pillow designed to provide support and comfort for the entire body. It is often used during sleep to help align the spine, reduce pressure on joints, and improve overall sleep quality. Body pillows come in various materials, including memory foam and polyester, and can be found in different shapes, such as straight or curved. Many people use body pillows for additional support while sleeping on their sides, especially pregnant individuals who may benefit from the extra cushioning. They can also be used for lounging or as decorative elements in a bedroom. Body pillows are available in various sizes and designs to suit personal preferences.
