This bookshelf not only has cool mid-century modern styling, it also has a great sustainability story. It is crafted out of Moso bamboo which is a giant grass that reaches maturity in 5 years or less, and releases nearly 35% more oxygen back into the atmosphere. Harvesting the mature stems does not harm the mother plant, so it is an endless resource. It is a dense fiber that is as hard as wood. Five thick gallery-styled shelves feature an exotic solid tiger center board and sleek angled ends. The double "u" style uprights give the illusion of shelves floating in a frame but with strong support.
