Soft, smooth and comfortable, our 400 thread-count sheet sets are designed for a healthy great night’s sleep. Choice is Yours: 100% Naturally-Sourced Cotton Sheets or Artificial Microfiber Sheets Luxury Hotels use 100% cotton sheets while cheap motels use Microfiber. At California Design Den, we prefer pure cotton above other fabrics, because cotton sheets are naturally easy on your skin, and regulate body temperature while microfiber gets hot and sweat building bad odor. Microfiber is made from non-biodegradable plastic which causes pollution, whereas cotton is from plants - safe, pure and natural. It’s the right choice for you and the planet. Made with Pure Soft Cotton and Lustrous Sateen Weave for Smooth Comfort Our sheets are made of 100% long-staple cotton with 400 thread count per inch, and a lustrous sateen weave for durability, and breathability. Rest easy with our soft sheets and pillowcases that are made using pure cotton yarns for ultimate comfort. Our smooth cotton sheets complement all kinds of decor to bring a lasting style and comfort to your bedroom.
