Give your mattress the finishing touch. Once you've covered your mattress in a mattress protector, finalize your bedroom by finding the perfect bed linens. Bed linens include bed sheets, a comforter (either a quilt or duvet), a duvet cover, if needed, pillowcases and shams. Generally, the duvet cover, or quilt, and shams will come as a set, as will the bed sheets and pillow cases. We recommend starting with the comforter then moving on to the sheets. It's easier to pick sheets that match a duvet versus the other way around. Whether youre looking to add bedding to your king, queen twin, full or twin XL mattress, we've got the bedding for you. Find a pattern or solid, fabric or fur and you're on your way to having a full decorated, trendy bedroom.
