We really like modular furniture and flooring, but modular shelving, like the How Does Your Shelving Grow? set, is definitely one of our favorite manifestations of the trend. Because the shelves are all individual units, they can be arranged to form one solid, conventional looking piece, or scattered to all corners of the room. These shelves are made from steel with a powder coat finish in grey, white or khaki (green). They come in multiple sizes and prices vary depending on both the size and how many units you need.
