Pillowflex has 40+ years of experience manufacturing pillows in the United States. We know the perfect blend of softness and fullness to give your pillow shams the perfect look. So wheather you need a pillow insert for your couch accent pillows or a bed sham, Pillowflex has the perfect size pillow for you. Our wide collection of quality pillow inserts is available in a variety of sizes to fit any size of bench, loveseat, couch, or bed. From 10 x 10 inches to 30 x 30 inches, you can use these pillows anywhere! For the most full and plump-looking pillow, your pillow insert must be larger than the sham so the pillows fill every corner. Our unique polyester fiber filling bounces back when compressed. For the best look to your new decorative pillow shams and to make sure they have nice full edges, please follow our advice. We recommend choosing a pillow insert that is 1 - 2 inches larger than your pillow shams so it fills the space and there are no flimsy, sad corners. Smaller shams that are 10 to 17 inches in size typically need inserts that are an inch larger. Bigger shams that are 18 inches and over typically require pillow inserts that are 2 inches larger than the sham. For rectangular pillow shams, we recommend pillow inserts that are 2" inches long or 1" inches larger on the length and width for the best look. Pillowflex offers dozens of hard to find sizes to fit any pillow sham you may have including euro shams, accent pillows, throw pillows, lumbar pillows, travel pillows, bed pillows and even sleeping pillows. . Our premium pillow inserts are created using American-made, high thread count poly cotton blended pillow shell and sustainably sourced fiber.

I purchased two of them. The sham covers (that came with the bedspread) fit well also. I like the fullness of the pillows and the quality of the pillow itself.
