IKEA KALLAX Shelf System

The IKEA KALLAX is a grid of square cubbies that has been the default bookshelf in student apartments for at least a decade. The reason it endures is that the modular format solves 3 problems at once: storage, display, and room division. At $70, the 4x4 version holds books, records, storage bins, plants. Whatever else you need to organize, and the cubbies are sized so standard storage boxes from IKEA's insert line fit exactly inside them. Assembly is straightforward enough that I did it alone in about 40 minutes with the included allen wrench. Particleboard construction is light enough to move without help but sturdy enough to hold weight when it is loaded and anchored to the wall. Credit goes to a team at IKEA that understood a grid of uniform openings is the most flexible possible storage format because it imposes no assumptions about what you are going to put inside. KALLAX replaced the EXPEDIT in 2014 with slightly thinner shelves. Caused an outcry from vinyl collectors who worried about the narrower dividers, but the structural integrity has held up in my experience. I have mine positioned as a room divider between my sleeping area and my desk. It functions as a wall that lets light through while providing storage on both sides. White finish shows scuffs and water rings easily, which is the primary argument for the birch or black-brown options if you want something that ages better. KALLAX isn't beautiful in the way that a custom built-in bookshelf is beautiful, but it's the best solution I have found for the specific problem of organizing a small space on a student budget. The fact that almost everyone I know owns 1 suggests the design team got the balance right between cost, flexibility, and appearance.
