Pocket Silver 22 is made with independent springs, each contained in a bag of hypoallergenic material, allowing for differentiated compression according to the weight and protuberances of the body. The padding is made up of “super soft” HR polyurethane foam on both sides, which makes the mattress relatively soft. The box system stiffens the mattress at the sides, for greater comfort when sitting on the edge or when getting out of bed. The cover in Silver fabric contains antibacterial silver yarn and is quilted with 100% polyester hypoallergenic fibre.
