Can anyone suggest a good mattress to buy under 12k

I have seen a few. I am getting a ortho mattress for 12 k but it's of durocare. Never heard of that brand. Others under same rate is non-ortho or semi ortho. What should I buy?

Not sure about ortho but I bought 4 sleepyhead mattresses last year...got pretty good deal 6k per piece and they are good, neither hard nor soft, appropriately firm.
