Key tips for furniture in small urban apartments include measuring your exact floor plan and maintaining at least thirty two inch clearances for movement. Choose multi-functional pieces like sofa beds or nested tables to maximize usability. Opt for scaled-down, human-sized furniture and round shapes to encourage flow. Prioritize anchor pieces first, then layer in accent furniture to avoid clutter. Light colors and minimalist designs can visually expand the space while durable materials ensure longevity.
