Regarding all the BS mattress reviews out there, one site I ran across while looking into pillows a while back was this one...
https://www.sleeplikethedead.com/
They seem to go out of their way to claim ...
"No Commission From Sleep Product Companies Or Retailers"
"No product endorsements"
"Independent from advertisers"
"Ratings based on 391,000 consumer experiences"
Our mission: "To be a true consumer advocate, not a marketing tool of sleep product companies masquerading as one."
At the very least, they have some pretty good tools for helping with narrowing down some starting points for a mattress or pillow, based on a variety of factors.
