The breathable cover on this Snuggledown Blissful Breathable Memory Foam Firm Support Pillow has been designed to allow maximum airflow, ensuring you won’t be left feeling hot and bothered! What's more, the cover is zipped, so you can take it off to be washed to keep it clean. With a new and improved soft formulation, this memory foam pillow features air holes that allow air to flow and reduce heat build-up. The cover also includes mesh side panels to improve the circulation of air allowing for a cool and comfortable sleep. Memory foam naturally adjusts to the shape of your body. It reacts to the heat the body produces and follows the contours of your head and neck to ensure your spine is aligned as you sleep. This means you can relax into a great night's sleep with this Blissful Breathable Memory Foam Pillow from Snuggledown and wake up free from aches and pains. With a deep profile and firm support level, you will benefit greatly from this pillow if you’re a side sleeper, as this shape eases pressure on your shoulders and gently encourages correct spinal alignment and posture.
