Planter. Seating. Storage. With modular Bison Cubes, the choice is yours! Bison Cubes make it easy to design a comfortable and beautiful environment. Bison Cubes integrate seamlessly with Bison Deck Systems. Instead of installing a wood deck tile, set a Bison Cube in its place for use as a planter or add a Bison Ipe top for seating and storage.
