Pillowflex Synthetic Down Pillow Insert 12x28 – Ultra Soft Down Alternative for Large Rectangle Shams

Cloud-soft luxury meets practical versatility

Experience a plush, down-like feel with the Pillowflex Synthetic Down Pillow Insert. This 12x28 inch insert uses a carefully engineered down-alternative fill that stays light, lofty, and comfortable, even after nights of use. The result is a pillow that remains cozy without the stiffness of stiffer foams or heavier fills. It’s designed to fit a range of shams, including 12x26, 11x27, and 12x28, helping you achieve a full, even silhouette that complements your bedding and decor. For best results, choose inserts that slightly exceed the sham size to preserve that lush, rounded edge.
