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 U-shaped. Many people use body pillows for additional comfort while sleeping or lounging. They are popular among pregnant individuals, as they can help alleviate discomfort and provide support for the belly and back. Additionally, body pillows can be beneficial for those with chronic pain or sleep disorders, as they promote better sleeping positions.
