The tiers of a pyramid are often handy illustrations to depict a hierarchy. And this three-tier, triangle-shaped decorative shelf might get you thinking of hierarchies as well. On the widest bottom tier, what groupings of items would work best together on the shelf? On the top and most narrow shelf, what's a single decoration that could stand alone in the spotlight? A picture framed filled with a special memory? A pot with a striking house plant, cultivated from a cutting from a tropical adventure? A candle to cast dramatic shadows across the ceiling? The sleek steel frame holds up to 15 across the three shelves, which are coated with an on-trend black matte finish.
