Body pillows are long, cylindrical pillows designed to provide support and comfort while sleeping or resting. They can help align the spine and reduce pressure on joints, making them popular among people with back pain or those who prefer to sleep on their side. Body pillows come in various materials, including memory foam and polyester, and are available in different sizes and shapes. These pillows can also serve as a cozy companion for cuddling, offering a sense of security and warmth. Many people use body pillows to create a barrier between themselves and their partner, promoting better sleep quality. They are often covered with removable, washable covers for easy maintenance.
