A friend had your mattress in a queen and I really liked it. I purchased a King but have to say the quality doesn't seem the same. On hers It was firm on the edge, mine you can feel yourself sink.
For the most part, I am pleased so far with the mattress. I have found it to very comfortable. My only complaint would be is that a couple times it has slept a little hot. But other than that I am very happy.
I haven't had my mattress that long and it's a little more firm than I expected. That said it's firm but then also plush and comfortable. So far tuft is a really good mattress
