Abstract: A pillow cover includes a flexible fabric configured to hold a cushioning material, a first, second, third and fourth connection element each positioned at a different corner of the flexible fabric, and a fifth and sixth connection element positioned along a central axis of the flexible fabric. A system for building pillow structures includes multiple pillow covers, each pillow cover including a flexible fabric having a plurality of connection elements positioned along a perimeter of the flexible fabric. The connection elements are positioned so that at least two of the plurality of pillow covers can connect in each an aligned-adjacent orientation, a staggered-adjacent orientation, an aligned-stacked orientation, and a staggered-stacked orientation.
