Shelving units come in a variety of configuration options including wall mounted, free standing, leaning and ladder, with features such as swivel, step, reversible and adjustable position. Designs range from heavy weight capacity industrial steel shelves, to artistic recycled paper constructions. Common materials include veneer, metals and medium density fiberboard.
Some storage shelves come with sliding drawers or shelf doors that include optional windows. Shelves that are designed to be used as a workstation often include a laptop table and cut-outs that allow cables to pass through to the wall. IKEA offers cabinet and storage solutions that are expandable and versatile. These units feature sections that can be added or subtracted to fit many room shapes and sizes.
