I have a large system of Ivar shelves that have followed me to multiple apartments, accommodating a truly massive book collection. It’s built to be expanded upon and its modular design can fit various apartment configurations. We used a set to build out our closet and a friend of mine has them stacked with bowls and cookware in her kitchen. They are graceful, lightweight, and versatile for use as plant stands, side tables, step stools and seating.
