Sleep calmly with our 400 thread count pillowcases that provide incredible softness, comfort, and durability. Choice is yours: 100% Naturally-Sourced Cotton Pillowcases or Artificial Microfiber Pillowcases Ever wondered why luxury hotels use 100% cotton pillowcases while cheap motels use microfiber? Cotton pillow covers are smooth, durable and naturally easy on the skin, while microfiber gets hot and builds odor. Microfiber is made from non-biodegradable plastic fiber which causes pollution, whereas cotton is from plants - safe, pure and natural. Hence at California Design Den, we prefer pure cotton above any other fabric. Pure Cotton Smooth Pillow Cases with Lustrous Sateen Weave for Ultimate Comfort Our pillowcases are made of 400 threads per inch, and a lustrous sateen weave for durability, softness, and breathability. They are made using pure cotton yarns for the most comfortable sleeping experience. Pair our pillow covers with a flat sheet, fitted sheet, duvet protector, and coverlet to bring elegance to your bedroom. Premium Quality Pillowcases (Two Piece) With a Perfect Fit - Authentic & Tested The 400 thread count pillowcases are sold separately and offer the quality and luxury of high-grade Egyptian pillowcases. Our pillowcases are made using the highest quality dye which is color fastness, machine washable and gets softer after every wash. The fabric is tested for no pilling, shrinkage, tear strength, and thread count authenticity for durability and easy care. Exceptional Craftsmanship to Create Safe and Luxurious Bedding Expertly and ethically made, our pillowcases are stitched to perfection to provide the look and feel of Supima and silk pillowcases for luxury, style, and comfort. Our customers are happier not just comfortably enveloped in soft breathable cotton but knowing our pillowcases were made without undesirable substances and pollutive substances.
