The supportive and comfortable Activsleep Reflex pillow is designed with a memory foam shell which responds to the contours of your head and neck to give you the support you need for a comfortable and relaxing night\'s sleep. This memory foam shell is ventilated to help increase breathability and airflow within the pillow to prevent overheating while you sleep so you can wake up feeling refreshed, revitalised and ready to seize the day. The knitted cover also features Purotex which releases friendly probiotics into the fabric to stop the growth of bugs and bacteria, this helps to reduce allergies such as asthma, along with keeping your pillow feeling new. Inside the memory foam shell, the pillow is filled with DuPont™ Serica® fibres. These lovely fibres are like little clusters which provide soft and bouncy support. All of this results in a medium to firm pillow that provides gentle and comfortable support.
