The pillows in this Slumberdown Memory Cool Firm Support Side Sleeper Pillow 2 Pack have a memory foam wrap which surrounds a firm and supportive hollowfibre filling to provide support to the head, neck and spine. With a soft knit Coolmax cover, this cooling material gently draws moisture away from your head to leave you feeling fresh and comfortable as you sleep. The pillows mould to your head and neck to relieve pressure and help to minimise neck or back pain. Having a firm support level, these Memory Cool pillows from Slumberdown are a great choice for side sleepers, or for those who prefer firmer, more deep pillows.
