The Leesa Legend (Costco best price) does a good job of aligning the spine into a natural position so your shoulder digs in but the small of your back doesn't. Excellent neutral position and support . A friend had purchased one for his very painful back (years of sleeping on a too soft mattress) and while the Leesa Legend was initially more comfortable than his prior mattress, his pain was still present. It took months, but the Leesa Legend rid him of back pain and now he knows what it's like to sleep in late, something the numerous points of back pain had always previously prevented.
I think it took him so long to adjust to a mattress, any new mattress,because so much was out of alignment with years of a bad mattress and it didn't just 'snap' back into place. At the four week mark, his arm stopped going numb, but between that point and the 3 month mark (the 90 day trial period) some different pains had occurred (things moving around in his back), and yet at around the 5 was has all gone and he no longer hates 'trying' to sleep. ALL gone. Perhaps it depends on how your back is and where you 'need' to go to ease the pain.
Actually the Leesa Hybrid, and the Leesa Hybrid Legend both received very good reviews for back pain. Both are a mixture of innerspring and memory foam. The Leesa Hybrid Legend is heavier (Queen size is, I think, at least 120lbs) and supposedly offers more support, yet people with back pain have really good things to say about the lighter (90lb) Leesa Hybrid.
Sidenote: When on sale at Costco, the price more than 50% of compared with the Leesa.com pricing, but the Leesa website always has sales on it's various products.
These mattresses are a foam/innerspring combination (HYbrid) so it requires full support, not just a perimeter bed frame (needs a platfom or slats). It's delivered to your home compressed in a box (which some buyers then get to 'shove' upstairs with a bad back).
In addition to a personal recommendation, I like to throw a few research/review sites into the mix. I found these sites highly informative:
https://www.sleeplikethedead.com/
https://www.sleepfoundation.org/mattress-reviews
https://www.mattressadvisor.com/mattress-reviews/
I think it helps if you consider whether you want to buy an innerspring, a memory foam, or a hybrid (combo) to help narrow down your search. These links helped me figure that out.
I will say I was suprrised at how important edge support turns out to be, because if you abruptly drop off the edge of a bed because the support is not there, you end up with a smaller mattress (fear of falling off).
Prior to the Leesa, I had always liked the independent coils on the Beauty Rest brand.
Maybe it's just popularity and not product, but the 'traditional' brands I grew up with, Sterns & Foster/Serta/BeautyRest didn't make it into any of the reviews I read. Newer brands Casper, Saatva, Ghostbed and Leesa were new to me, but seemed to get better reviews.
