Needed to replace existing 20x20 down pillow covers for my study sofa, saw these Boho Beige Woven accent cushion covers and thought the soft coloring, woven texture and pattern would add a soft neutral color palette appeal to the other pillows and room decor. The cases arrived quickly but upon opening the clear plastic packaging, they smelled stale and musty. Called Wayfair, they quickly and seamlessly shipped a replacement. The specification stated 20x20, but one was 16x16, the other 17x17 making it a tight fit and very solid stiff pillows. Good thing my pillows were down and able to be squished into the smaller case, I don't think a polyester would have as good results. Plain back, designed front. The front weave is seen going through the material so if the treads gets pulled, the material will bunch up. The backing feels like a thick cotton material and front is a polyester blend. There wasn't a inside manufacturers label describing materials (site stated polyester) or care instructions, had to revisit the site to see how these cases needed to be cared for (hand wash recommended). Watch out for the zipper, well hidden but gets snagged easily and doesn't glide with ease. Since now my down pillows had "shrunken" in size, I will need to search for a true 20x20 pillows cases so they be higher on the sofa. One picture shows three pillows, the middle fringe pillow is a 20x20, the first pillow is the Boho Woven case as 16x16 (site states 20x20). With the down pillow stuffed inside, the pillow is very heavy and stiff. You may want that look but I wanted a softness.
