The Cotton Quilted Mattress Protector by Bianca is made from durable cotton japara fabric. Unlike all the other polyester and plastic protectors teh 230gsm pure cotton protector is cool and comfortable with a 50cm fitted skirt to fit all mattresses. I purchased two and are extremely happy having had two waterproof plastic type towel ones that made us hot and sweaty unable to sleep. Very happy with the Bianca Brand of Cotton Mattress Protectors.
