Bought two of these in dark turquoise blue which looks great on my grey sofa.  Can be placed along the sofa arm or used for lumbar support.  The cover fabric is thick, soft, quilted cotton with an inconspicuous and good quality zipper.  Very nice to have a removable and washable cover to keep the pillow fresh.  I washed the covers in cold water with gentle spin and they came out clean and intact.  Laid them on a rack to air dry just in case there is any risk of extra wear and tear (pilling) or shrinkage in the dryer.  The pillow insert is soft and the tight fitting cover preserves the shape.  Happy to recommend this bolster pillow to others.
