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, it's 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.
