Do Expensive Mattresses Really Improve Sleep Quality or Just Marketing?

I’ve been seeing a lot of high-end mattresses claiming better sleep and less back pain.

For those who’ve upgraded to a more expensive option did you actually notice a real difference, or not much change?

Trying to decide if it’s worth the investment.

We bought a Casper mattress thru Sam’s Club and it has made a big difference with our back pain. It comes in a roll and you have to let it expand for a couple of hours. Hope this helps!
