Matress recommendation

[jessafina]

I don't know exactly where to post this, so hopefully the mod can help me if I should be elsewhere...

We are moving and looking to get a King size mattress (so as to fit DS and one on the way). I'd like a non-toxic mattress option if possible. I currently have a queen size Novaform from costco and I love it, but I've been reading that they can be kind of toxic, especially when they're first airing out.... 

So i'm willing to get something else, just wondering if anyone has  a mattress that they're in love with!

We have a Nature's Rest mattress that we bought, I think, at one of those discount furniture places. We've had it five years now, and while it is pretty soft and can seem saggy if we don't rotate it frequently (12 weeks-ish), we sleep so much better on it than on any other mattress anywhere else. It's latex, which I think is pretty healthy, if I remember correctly..
