Muuto's Stacked Shelf System Perhaps one of the most versatile of the bunch, the Mutto Stacked Shelf System will grow or shrink to meet any of your needs. The design is quite simple, and that is exactly where its beauty lies. The "building blocks" come in three sizes: small, medium, and large. They can be arranged randomly, or systematically and are secured with a clip for added stability.
Steven Burks' Circus Shelf The Circus shelf has garnered lots of attention in the last couple of months, and rightly so. The shelf comes in three sizes (one, two, or three shelves), and will fit well into any modern apartment. The wire cages plug easily into the pine shelves, which means easy assembly and disassembly — no tools needed!
Tetrad Mega Shelving System Clearly resembling our beloved Tetris, the Tetrad Shelving Unit is quirky, beautiful, and versatile. But more importantly, come moving day, it will easily come apart and fit into the most compact of moving trucks.
CB2's Hive Storage Unit Interesting, durable, and stackable, CB2's Hive Storage Unit is great in any room. Stack a few to form a display shelf, or buy a couple and use them in the living room as magazine racks, or in the kitchen to hold nicknacks. Oh, and lets not forget: it's from CB2, so it won't break the bank.
Muuto's OTO Storage System Lastly, Muuto's OTO 100 Storage System is clearly unique. Its round shelves in varying sizes will hold your most precious books, and collectibles, and will bring a modern edge to your room, all the while keeping the look soft. And like the other shelving units in this list, the OTO 100 Storage System can be assembled and disassembled very easily, and can be arranged into many formations.
