Bold geometric duvet covers are a great way to welcome overnight guests. As the largest piece of furniture in a bedroom, the bed instantly sets the tone in the space. Bed linens like these are cheerful, attractive and make your guest room look crisp and clean. Some of these even have different front and back prints, giving you two different looks.

These patterns are modern and not frilly, making them accessible to both men and women. Plus, you won't find any polyester here: they're 100% cotton.
