Overheating at night is one of the biggest causes of sleep disturbance – that\'s why we created the CoolSense pillow. It is covered in cooling fabric to help regulate your body temperature and prevent over heating as you sleep. It\'s even cool to the touch. Inside the pillow lies a ventilated memory foam shell. The ventilation allows air to escape from the pillow for a fresh and comfortable sleep environment. The memory foam shell is lovely and soft, unlike traditional memory foam which can be very firm. To create support for the head and neck, a foam block lies at the heart of the pillow and is surrounded by hollowfibre. But this isn\'t just any hollowfibre, its DuPont™ Cotrano® fibres. This fibre feels just like cotton and is soft, bouncy and durable with great recovery properties. Above all, the pillow is supportive, yet comfortable and is medium/firm with a slim profile, which is ideal for back and side sleepers.The Sealy CoolSense pillow is hypoallergenic which means that it is made from \'clean\' materials and doesn\'t contain anything that is likely to cause allergies. It even comes with a two year manufacturer\'s guarantee.
