While in deep sleep, our body asks us to be in contact with natural materials in order to fulfill effectively all the functions necessary for our daily psychophysical regeneration. Anything that disturbs this balance can compromise it. Therefore, every material in a Pedano mattress has a specific function. The internal structure is always made of pure natural latex with a covering of pure Alpine virgin wool. The addition of turf or straw conveys specific curative qualities to the mattress.
