Right now I have an incredible 14 inches of Queen memory foam I got for $400 that's incredible to sleep on. The brand? A no name.
What I've taken away from the mattress craziness is that if you exclude the fancy things like temperature adjustment and sleep number stuff, most basic mattresses come down to basic material and then secondly firmness. As long as you get those two things right they kinda all seem to be the same.

Some U.S. public libraries offer access to Consumer Reports for free with a library card.
sadly, consumer reports now gets money from purchases through amazon affiliate links
I would still place more trust in Consumer Reports than in for-profit review sites, but that trust has declined.

That’s how i found a mattress that is still like new after 6 years of usage (and I’m extremely satisfied). And no, none of the “big” brand.
Here a rule of thumbs, avoiding a brand that start by “s” is already a good start. Then there is a few more to filter out.
