Cervical Pillow for Side Sleepers: A cervical pillow made specifically for side sleepers is designed to meet the particular needs of people who often sleep on their side. Memory foam pillows are durable. The memory foam material is made of high-quality polyurethane, which is highly durable and resilient, and can maintain the pillow's shape and performance for a long time. These pillows often have a higher loft on one or both sides to fill the space between the head and shoulders and maintain good spinal alignment as you sleep. This cushion aids side sleepers in avoiding strain and pressure on their neck muscles, so they may wake up more refreshed and pain-free by providing tailored support for the neck and head.
