The Slumberdown Memory Foam Plus Firm Support Side Sleeper Pillow 2 Pack are memory foam with a difference. A pressure-relieving memory foam wrap surrounds luxury cloud cluster filling, resulting in pillows that are both super supportive and wonderfully comfortable. The pillows mould to your head and neck to relieve pressure and help to minimize neck or back pain. Having a firm support level, these memory foam plus pillows from Slumberdown are a great choice for side sleepers, or for those who prefer firmer, more deep pillows.
