Why can entering IKEA with a task like buying a shelf turn into noticing rooms, lamps, textiles, and storage ideas before the shelf is picked up?

Answer: Its one-way route leads everyone through furnished rooms and then the accessories hall, turning the errand into a tour

Price tags anchor shoppers to the first expensive item they see — Wrong. Price tags matter at IKEA mainly as the labels that tell you where to find an item in the self-serve warehouse. Comparing prices does not explain why you meet whole room settings before you reach a single shelf.

Its one-way route leads everyone through furnished rooms and then the accessories hall, turning the errand into a tour ✓ — Correct! IKEA lays its store out as a single winding path: first the showroom, where furniture is arranged as real rooms you walk through, then the market hall of lamps, textiles and storage, and only then the warehouse where the shelf you came for waits. Because you cannot skip the scenes, a task turns into a sequence of discoveries, and the small things you noticed on the way end up in the trolley.

Shoppers simply wander at random once they are inside the store — Wrong. The route feels meandering, but it is a planned one-way path with named zones in a fixed order. A random layout could not reliably move everyone from imagining rooms to picking up accessories to collecting the shelf at the end.
