Then perhaps try searching "mattress materials", "history of mattresses" or "mattress making tutorial".
Plenty of relevant results, zero ads.
When somebody searches "mattress", 99% of the time, they want to buy one.

This is unfounded I suspect but it would be a reasonable justification for Google's results.
My point is, searching for just mattress should reasonably and logically include a small sampling of 'all' related topics. As by your own words, specific implications behind the search should be left to additional keywords. Assuming the search is for the purposes of buying, without specifying that, is certainly more profitable to google than a small sampling of all related topics, but not what most users want when simply searching for a vague general thing or concept.
Search engine A, when someone queries "mattress", shows a page of options to buy a mattress.
Search engine B, when someone queries "mattress", shows a light touch on a number of different aspects of mattresses, including a history, the wikipedia page, and so on.
Which one is doing a better job of showing relevant results to the user? I would suggest A.
