I'll start this off saying I've only been using this mattress for a month and I will say it has served well so far and the missus has been sleeping far better than she used to. Personally, I sleep where I sleep, but to steal her words, it feels something like a nice heavy pillow on top with a stiff base. Nicely soft, but still supportive and I do notice that my muscles recover much faster.

Can't speak to durability yet. I'll put it through its paces as I can and if the foam falls through and I start seeing any deflection I'll definitely be back to edit this review.
