Opinion please

I have read the durability guidelines but I am unsure about a couple of things so I wanted to ask your opinion of this. $1699 for this mattress. I have actually tried this mattress and it is very comfortable and gives proper alignment. That is not a typo, the 1.5lb is listed twice. It lists the quilt then FR fibers then the 1.5lb foam, I guess they are all part of the cover? Any concerns here?

Hi Napper,

That sounds like the Pranasleep Moon Plush. My one concern would be the total of 2" of 1.5 lb polyfoam in the quilt. It uses a larger tack and jump quilt pattern, and my concern would be 2" of the plush 1.5 lb poly in this configuration might lead to excessive softening/depressions in a shorter period of time as compared to the other componentry within the mattress, which is of a higher quality.
