Not measured yet

This sector has not been measured yet

The question set for mattresses is ready: 8 buying questions and three personas. The index runs part of the sectors each week within a fixed budget; this one is due within 4 weeks. Until then we show no numbers here — a sample leaderboard would suggest a measurement that never happened.

The 8 questions we ask

  1. 01Welk matras is het beste bij rugklachten?
  2. 02Wat is een goed tweepersoonsmatras onder de 1000 euro?
  3. 03Waar koop ik een matras met een lange proefslaapperiode?
  4. 04Pocketvering of traagschuim: wat is beter voor zijslapers?
  5. 05Welke matrassenwinkels in Nederland geven eerlijk advies?
  6. 06Welk matras is geschikt voor een boxspring?
  7. 07Waar kan ik een matras kopen dat binnen een week geleverd wordt?
  8. 08Welke matrasmerken hebben de beste garantie?

Without a brand name, in Dutch, with the Netherlands as market. The same set every week.

The personas behind the questions

  • Stel dat een tweepersoonsmatras zoekt met verschillende hardheden
  • Iemand met rugklachten die advies zoekt over ondersteuning
  • Starter met een klein budget die online wil bestellen

Personas and questions are in Dutch: the index measures the Dutch market.

How this was measured

  • 01Every question goes to the engines through their API in a clean session: no account, no history, no personalisation.
  • 02Brand names are extracted from each answer (text extraction). Per brand the decision layer judges whether it is a real brand in this sector, whether it is a marketplace, how it is spoken about and how prominently it appears. That certainty is shown in the table.
  • 03Brands only count when the probability that they are a real brand is at least 50%. Borderline cases are left out.
  • 04Share is measured over a four-week window with a 95% confidence interval. Names that turn out to be the same company are merged once the decision layer confirms it.
  • 05Engines without a usable API (such as Google AI Overviews) are not in this index. Browser captures of consumer products follow once the capture service is publicly available; those will be labelled separately.
