tl;dr: IKEA names products with real Swedish words (4-12 letters, ideally containing Å, Ä, or Ö) instead of numbers, a system started by founder Ingvar Kamprad who struggled with numeric codes. Names follow category conventions—sofas get Swedish place names, bookshelves get men's names, children's products get animals/nature—and are vetted to avoid trademarks, surnames, and unwanted meanings in other languages. IKEA names 2,000-3,000 new products this way each year.
