Extra Length, Elevated Comfort
At Boll & Branch, our process starts with the seed. Our Twin XL Fitted Sheets are 100% organic, long-staple cotton. Woven in our signature 4-over-1-under weave, the fabric naturally softens over time, getting cozier and warmer with each wash, without relying on synthetic treatments.
Designed to fit snugly on Twin XL mattresses, these sheets offer a secure, tailored feel that stays in place all night. Breathable, light, and toxin-free, they’re ideal for sensitive skin and all-season use, making them a favorite for growing teens, college students, and anyone who needs a little extra length without sacrificing luxury.
From farm to finish, our sheets are crafted through a transparent and ethical supply chain, delivering better bedding that feels as good as it does right.
