Gorgeous organic cotton Sateen sheets are smooth for a restful night's sleep. These sheets are luxurious and beautiful and environmentally sound. Choose from either sheet "sets" or you can also purchase flat and fitted sheets and pillowcases individually. Coyuchi bedding uses upland cotton for its heartiness and yield which is grown organically in India. This means communities and individuals are spared exposure to herbicides, insecticides and chemical fertilizers, have better soil quality with improved water retention and overall maintenance of their ecosystems. Once harvested the cotton is minimally processed without chemicals or resins. Minimally processed means only washed, dried, sanforized (a mechanical processing involving a rubber pad and heat), no softeners, no resins - nothing else. The thread counts vary from fabric to fabric and with each production run but are always in the 250-300 range. We recommend buying bedding based on feel rather than thread counts which has become a buzz word among conventional bedding. Note: Color variations are common among organic cotton products. Variations in climate, rainfall and time of picking all affect the color of the cotton. This means that each lot of yarn and fabric is unique. These color differences assure the product has not been dyed and reflect nature's subtle changes from season to season and field to field. Fitted sheets accommodate up to 15" mattress depth.
