What is natural cotton?
Our cotton covers are not “certified organic” but we select our cotton suppliers carefully for their respect for the earth and for avoiding unecessary harm to the environment. During the growing and manufacturing process the cotton is exposed to as little chemical process as possible. Vegetable based dyes are used to ensuring bright, energising colour direct from nature itself.
