A Natural Choice for Elevated Sleep
Unlike conventional sheets that rely on high thread counts or chemical softeners, Boll & Branch focuses on what truly matters: the quality of the thread. Our Signature Fabric is woven in a unique weave using long-staple organic cotton, creating a soft, breathable fabric that only gets better — and smoother — with every wash.
Perfect for layering or as a standalone top sheet, our King Flat Sheets offer versatility, durability, and comfort that never compromises on purity. They're an ideal choice for anyone who values safe, sustainable materials and transparent sourcing.
Choose from a range of fabrics and patterns, allowing you to customize your King-size sleep setup according to your needs. If you’re a warm sleeper, our Linen and Percale sheets will keep you cool through the summer. For colder months, try our Flannel offering.
