Structure made up of independent pocket springs, one by one, with a smaller diameter than the Bonnel, but the number contained in it is more than double (736 springs in a 160×200 cm mattress); the independent springs compress more or less depending on the weight and bumps of the body, creating an ergonomic position. Mattress suitable for daily use. The upholstery is in “Silver Tech” fabric, built using threads with silver fibers in an intimate blend in the yarn, performing an excellent antibacterial action. The conducting capacity of silver also allows for a valid anti-stress and anti-static action. The “Silver Tech” fabric is quilted on the winter side with Pure Virgin Wool Woolmark®, while the padding on the summer side is in 100% Cotton.
