100% Cotton We are a small, family-run business, and every order means a lot to us! Please review the product details carefully before purchasing to ensure it’s the right fit for you. While we do accept returns, we kindly ask that you shop thoughtfully, as frequent returns can be challenging for a small business like ours. Thank you for your support! NOT ACRYLIC (100% COTTON): Most knit covers on Amazon are made of Acrylic (basically soft plastic) that traps heat and pills after one wash. Ours are 100% thick-gauge Cotton. You can feel the weight difference instantly. NO SWEAT, LITERALLY: Synthetic pillows make you sweat because they don't breathe. Our natural cotton knit lets air flow through, so it stays cool against your skin. Great for naps, not just decoration HEAVYWEIGHT TEXTURE: This isn't a flimsy printed cover. It’s a chunky, actual knit texture that feels like your favorite heavy sweater. It holds its shape and doesn't look "cheap" on your sofa. MACHINE WASHABLE: Life happens. When it gets dirty, just unzip it and toss it in the wash. It’s durable cotton, so it handles the laundry without falling apart or losing its softness. Size: Measures 18x18 inches and fits standard square pillow inserts. For a plush, fuller look, we recommend using a 20x20 inch insert. Giftable Presentation: The pillow cover is presented in an attractive hard packaging box, making it an ideal gift for housewarmings, weddings, or any special occasion. Revamp your living space with this vibrant pillow cover, featuring a bold mustard and contrasting light blue checkered pattern. The alternating stripes offer a modern and eye-catching aesthetic, making it a perfect accent for contemporary, eclectic, or minimalist interiors. Crafted from a durable and soft cotton blend, this cover ensures both comfort and longevity. Designed to fit 18x18-inch inserts or provide a fuller, more plush look with 20x20-inch inserts, it is finished with a hidden zipper for a polished appearance. Easy to care for and machine washable, this pillow cover is a stylish and practical addition to your living room, bedroom, or office.
