Based on our discussions, wanted to highlight a couple of the good memory foam mattresses. There are many brands that sell foam mattresses including Purple, Casper, Tuft & Needle, Zinus, and now Amazon has their own. The two that really pushed the prominence of affordable memory foam are Casper and Tuft & Needle. They’re the two I like to recommend as I’ve tried them both for a good amount of their 100 night sleep test offer. If budget is no option, you may be best off looking at brands like Sleep Number which I hear are excellent but not friendly to the budget.
At the top of the market, in my opinion, for affordable known-good brand is the Caper:
While it prices double to the Tuft, my sleep test resulted in sticking with Casper. I would avoid the new “Hybrid” models as they are either fancy, small benefit options or re-introduce coils into the bed. Once you head down the path of coil mattresses, I think you have to evaluate a large lineup of offerings.
Affordable, good customer service, entry memory foam from a known-good brand:
The price range for this one is around 650-750.
