Big name in flat-pack furniture

IKEA

This Swedish retailer is known for its meatballs almost as much as its self-assembly bookshelves and sofas. Look for the four-letter name that starts with an "I."

This clue points to IKEA, the Swedish company famous for its affordable, ready-to-assemble furniture sold in flat boxes. The term "flat-pack" directly refers to how IKEA products are packaged, making the answer a straightforward reference to their brand. It’s a cultural shorthand—most people instantly recognize IKEA as the go-to name for this style of furniture. No wordplay here, just a clear nod to their global reputation.
