MUST BUY!
Alright here's the skinny on the 2. 0 Mattress. I'm a mid-thirties male, very active, train twice a day 4+ days a week. I bought the King Size 2. 0 and it came condensed, so I was able to lug it up my stairs on my own outside of the cardboard box.
I have been sleeping in it for over a week now and it is absolutely AMAZING! I used to sleep good, I would have some deep sleep and can sleep for a while, but I have never gotten more consistent deep sleep then this last week on this mattress, I have had so many dreams every night throughout a lot of the night, it is an unreal feeling actually.
I had a softer mattress prior to this one and every time I would sleep on someone else's mattress that was more firm, my body would feel better, so thats why I wanted this mattress and its going to be a huge game changer for me, it is much more supportive on the main body parts (back, hips, etc).
Some reviews mention it smells strong, it just smells in the beginning because obviously its wrapped in plastic and condensed for so long, it needs several days to air out, but after 7 days, I can tell you the smell is pretty much gone and is well worth it.
