This is a 100% cotton nubby, lightly textured, woven pillow. The woven dimensioning will not release with use or cleaning as it is woven INTO the pillow structure. The back is a matching cotton duck and features a zippered closure for ease of fill and cleaning. Stand alone or use as a layering piece for traditional or southwestern styles. Hypoallergenic poly core is made from the softest, fluffiest fill available, so it retains shape day after day. Spot clean for care.
