Bamboo fabric, a relatively recent addition to the bedding scene, is praised for its eco-friendly nature and similarities to silk. Like silk, it’s breathable and insulating, so it works for summer as well as winter. The bamboo typically has been grown sustainably and pesticide-free. The fabric maintains the same antibacterial qualities as the plant and has been known to prevent bedbugs.

Silk is chosen primarily for its lightweight and luxurious feel. Its unique texture helps regulate body temperature, so it works well for winter or summer. When buying silk sheets, go for quality — a thread count of 400 or higher tends to be the best. The weight value — also called the momme — determines quality too. Anything with a momme of 19 or higher is excellent quality.
