Feather bed protectors are 100-percent Cotton, double stitched, and have invisible zipper with tear drop closure. In your regular cleaning of protectors we suggest machine washing with a regular detergent in cold water, tumble dry low. It is crucial that the zippers be closed during washing and drying to prevent damage to the zipper. After a long day you can climb into bed, remove all pillows, except your one favorite Down Etc. pillow, pull back the comforter, and the cushioning of the feather bed beneath you combines with the softness of the down comforter to provide the ultimate in restfulness. They even adjust to your body temperature. Go ahead and give the full weight of your head and neck to the pillow. Relax from head to toe. Our Feather Beds are double layer fabric on top and bottom, 100-percent downproof cotton and super soft. The feather bed protector ensures that your feather bed stays fresh every day.
