The interesting part in my opinion is that in the mattress market this branding system seems not to work.
That reputation needs to be established by either word of mouth or general reviews. For mattresses, word of mouth isn't that good because people have different preferences.
Moreover, general reviews have essentially been corrupted by 'astroturfing' reviews. That is, almost all mattress reviews that are prominent are financed by a manufacturer. They then use publishing clout or heavy SEO to be found over any possible remaining reviews. Besides, single user reviews aren't that valuable because of personal preference and lack of comparison mattresses. Thus, it is really hard for an honest reviewer to start. They need capital to get sufficiently many mattresses. Then, they need to be found, thus going up against the heavily SEO'd dishonest sites. Finally, they need to stand up to all attempts from the mattress companies and dishonest reviewers to actually survive.
Finally, bad-mouthing brands' product quality is again stymied by personal preference and the small number of mattresses anyone sleeps on.
Here I'm not sure the name Bosch is worth anything, and you might as well buy a Zanussi, our student flat had all Zanussi stuff and nothing broke in the 10 years they had them.
