This quality Airfresh mattress is ideal for kids. It is made of polyester microfiber, which allow the airflow to be at its maximum throughout the whole surface: no need to turn it over in summer or winter with its "all season" sides! Similar to the sport clothes technology, the quilting absorbs body's heat and removes perspiration. Its stretching properties bring softness to the mattress. It is treated to be anti-bacterial and anti-microorganisms.
