There are various top mattresses with many different fillings, such as resilient foam, comfort foam, wool, latex, visco and horsehair. In general, these fillings are experienced as stiff and hardly add anything in terms of extra comfort. By contrast, the Featherbed shapes itself perfectly around the body and provides for a soft, noticeable topper, due to its resilient down and feathers. You could say that ‘it’s like sleeping on a cloud’.
