Natural fillings are commonly used in better quality mattresses. These fillings range from cotton & wool to more luxurious fillings such as silk & cashmere. Benefits from a mattress containing natural fillings not only include their great bounce back ability (which means your mattress will stay more plump for longer, maintaining comfort and increasing its lifespan) but also its ability to regulate body temperature. In essence, you'll be kept cooler on those hot summer nights and warmer during the cold of winter. If you need any further assistance in choosing your perfect mattress, we are here to help!
