The Memory Airflow pillow by Sealy uses the very best Posturepedic technology. Memory foam provides lots of great benefits such as responding to the contours of the body and providing just the right amount of support for you. Overheating is one of the main culprits for a bad night\'s sleep – no problem. The Memory Airflow pillow used ventilated memory foam which allow heat to escape from the pillow to prevent overheating. Unlike other memory foam pillows, the memory foam shell is not hard, its actually lovely and soft. The centre of the memory foam shell is filled with DuPont™ Serica® fibres. This fibre feels soft, silky and spring like and this results in a comfy pillow with medium support. The pillow is covered in a quilted cotton cover with air mesh walls to increase airflow. You can even remove the cover for machine washing to keep your pillow feeling like new for longer. The Memory Airflow pillow is hypoallergenic which means that it does doesn\'t contain any materials that are likely to cause allergies. It even comes with a two year manufacturer\'s guarantee.
