Air vents in mattresses provide much needed airflow through the mattress. They tend to feature on higher end mattresses that contain a lot of fillings. The mattress air vents help keep the fillings fresh and dry, plus the air vents also help expel any stale odours that can build up within the mattress.
The number of air vents can vary on an air vent, but are always strategically placed around the border of the mattress, to achieve maximum airflow.
