This is kind of interesting: the first corrugated cardboard modular shelving system, Jeff Beene's Cadence Shelving System. We like that the composition is 30% recycled materials, that the shelves are modular and have the comfy feel of corduroy fabric. Apparently they're easy to flexibly configure and assemble. And the finished construction reminds us vaguely of a PacMan screen, for which we have a certain fondness. We're intrigued but not entirely sold. Part of furnishing a home is the satisfaction of creating a feeling of rootedness. Cardboard doesn't get us there. What about you? $493.75 buys a 6-cube kit from CardboardChair.com.
