"Reviews" are useless, in fact, they are worse than useless, they are just another form of spam. Those reviewers and bloggers make their living on commission, thus the incentives are not aligned. You can find positive reviews of pyramid schemes and malware.
Mattresses are in a way kinda interchangeable. Sure there's different quality and a well worn mattress will be different from a new one, but, in general, you probably aren't going to sleep differently on a different brand of a similar quality mattress.
About 6 years ago I read that people who bought their mattress from the internet we're just as satisfied with their purchase as people who tried them out in the store beforehand.

Plus most people's opinions suck anyway.
