The Casual Home Bookcase features genuine wood, a material scarcely used by other shelving units. Its only drawback is some buyers have complained the color is less dark espresso and more cherry red, a complaint mentioned on more than one product on the list.
The Ollieroo is the only other bookshelf made from natural materials: the solid bamboo makes it a sturdier choice than composite wood, but bamboo is still thin and cannot hold more than 22 lbs. per shelf. Even so, buyers rave that is easy to assemble and love the fact that it is made from natural materials.
If you are willing to buy a shelf made from synthetic material, the eHemco 5 Tier Bookcase Shelf Ladder comes in a variety of colors, including black, white, and grey.
The black shelves of the Convenience Concepts American Heritage Bookshelf Ladder adds a nice modern finish to a room, but some buyers give it mixed reviews. Some say that while it's a value buy, they note that it is flimsy, sometimes shipped with missing screws, sometimes has incorrectly drilled holes, and that the color was somewhat different in the product photo.
Another bookcase is the eHome Products Leaning Ladder Wall Bookshelf. Like with other shelves, buyers complain that the color isn't quite true to form- more red than brown. But the raised edges ease the struggle of the contents falling off the shelves.
