All of our sheets and comforters are made from natural and responsibly sourced materials. Most of our sheets are made from cotton with a few manufactured from bamboo. Our cotton is by far the most-loved fabric for our sheets. Some of our cotton is sourced from Egypt or Europe, making our sheets the most soft, durable, and breathable set of sheets out there. Also the thread count in most of our sheets and comforters is high, assuring the best hand soft and luxe feel touch. Thread count refers to the number of horizontal and vertical threads per square inch. Generally, the higher the thread count, the softer the sheet, and the more likely it will wear well — or even soften — over time. Good sheets range anywhere from 200 to 800, although you'll occasionally see numbers over 1,000. Our sheets made from bamboo-derived threads are soft and silky, but they can be more delicate and more expensive than their cotton counterparts. Bamboo is considered a green option and is more sustainable than cotton. Browse through our different products and brands of sheets, comforters, and duvets to choose the right one for you!
