What's the deal with these Tuft and Needle mattresses?

I heard about them on here and am intrigued. I've never loved those foam mattresses--granted I've only slept on one a night or 2--but I'm trying to correct a horrible mattress purchase I made previously.

My wife and I must have mattresses shopped for 6 months before finally pulling the trigger. No matter where we went, we kept coming back to this Stearns and Foster we fell in love with. Only problem it was 3k for a king. Way too much. But we got some tax money in right before we moved in our new house, so decided to spend on furniture. And one of those mattress stores on every corner had a "refurbished" one--one that someone slept in and brought back (I think you have 90 days)--but it had been de-licked/bed-bugged, whatever. Half off!!

Sweet, right? Only $1,500 for the mattress we were in love with and they were throwing the box springs in for free! Such philanthropists! The catch--the haunting, fricking, cocksucker of a catch--was that you forfeit your right to return it. No 90 night guarantee. No big deal, though, we've laid on this mattress several times in several stores. What could go wrong? Well, the damn thing is like sleeping in quicksand. A water bed is easier to get out of. And not those expensive, firm water beds that some kinky parents had back in the 90s, I'm talkin el' cheapo, kiddo, 80s/90s, noisy as shite, water bed death traps. I literally had to get my 7-year-old to come grab my hand and help me up some mornings. I thought about installing some sort of hospital-like trapeze from the ceiling that I could hoist my old fat arse up with. And it hurt my back something fierce.


tl;dr Anybody know anything about those Tuft and Needles?
