Man, we've been going through beds over the last three years with no success. A lot depends on if you are big, or a side sleeper vs back sleeper. Do you sleep hot? yada, yada. My wife does all this research and keeps a spreadsheet based on me being large and a side sleeper.
We have done Nectar, Latex Mattress Company out of Phoenix, we are on Saatva now. I think we have had another one that I can't remember now. We bought the adjustable base when we bought the Nectar as I had shoulder surgery a few weeks later so I could be in zero gravity. The adjustable base is so great. None of these beds have been great for either of us. Which is odd because we had the Latex Mattress Co. for like 15 years before I finally caved my side enough that I was constantly sinking to the middle.
Good luck finding a mattress. I'm wanting to look at Sleep Number next just so I can adjust it based on hip or back pain.
