The Dream Essential Side Sleeper Memory Foam Pillow features an ample layer of memory foam and high airflow pockets in order to give side sleepers a gentle head and neck lift night after night. It is designed to cradle the neck for a side sleeping experience, plus it can help relieve muscle fatigue and tension. Luxury is in the detail, which is why this side sleeper pillow is covered in a soft, 100-percent polyester removable cover with blue piping. The machine washable pillow is filled with 100 percent polyurethane foam filling that is both durable and comfortable. Memory foam bed pillows maintain their shape and do not get flat even after repeated use. When you want more than a standard pillow, a Dream Essential Side Sleeper Memory Foam Pillow is a good choice.
