Hi passionate4nature,
Livefortomorrow was one of the many names of a company that caused a lot of people a lot of grief over the years with their many bankruptcies (they are still operating today under a different name). See post #6 here. Of course that doesn’t matter in this case since you aren’t buying from the company itself who is no longer in Plain City.
The mattress itself uses organic wool and cotton but the latex isn’t organic as I mentioned so it certainly isn’t 100% organic. The latex is natural … not organic.
This depends entirely on how the mattress works in terms of PPP (Pressure relief, Posture and alignment, and Personal preference) and on whether you think you need another layer and why and of course how comfortable you are with buying it in the first place.
I’m not sure what you mean by “total density”. Density is a measurement of either kg/m3 or lbs/ft3 and doesn’t have a “total”. It’s usually used for polyfoam, memory foam, and Dunlop latex. With Dunlop it’s directly connected with the firmness of a layer. I’m not clear on what you are looking to do (or buy) or why you are thinking of adding another layer though.
