After spending thousands over the years for a variety of 3 foot high fancy pants expensive padded uncomfortable name brand junk last time I went with the cheapest sealy “firm” mattress from J.C. Penney. $700 total for cal king mattress and box spring. Best I have ever had by a mile. A basic firm mattress is the way to go for me. 3years in and it is still nice and solid. Every other one I had would develop pits and valleys, I always felt like I was falling down a hole into hell when I climbed in bed. Firm is much better for the back than settling into a pile of foam IMO. It is comfortable, I sleep great, I have no pains, done. YMMV of course.
No use trying to figure out the brand and model by your research and recommendations. The whole mattress industry is a marketing joke based on obfuscation. They make the same mattress but give it a different name for different stores that sell them so they can make comparisons difficult. And they change the names around constantly for the same mattress. There are no logical specifications that allow you to compare different versions. All you can do is try one and see if it works for you.
