The Allegro has the feel of a firm, traditional European mattress. Its double sided make-up offers firm or extra firm with just a flip of the mattress. For those who agree that only a firm mattress will do. A classic feel that never goes out of style. Try it with the thinner Classico Standard pillow or the thicker Classico Maxi pillow for a plush, breathable nest of contouring support and comfort.
