Phoenix thanks again for your prompt response. What I was talking about is the pictures you shown here:https://forum.mattressunderground.com/t/ikea-mattress-cutaway-pictures
When looking the one for the latex myrbacka correct me if I am wrong but the first 6.5" are pure synthetic latex and then the last 2" are the high-resilience polyurethane? I am surprised if is like that. And it seems that there is no other top layer of anything, for example in the dreamfoam case the top layer is not latex but hyper flex foam i wonder is that’s an advantage of disadvantage.
But still you mention that that the latex in the dreamafoam mattress is higher quality, but what about the lower layers, I think high-resilience polyurethane is better than HD poly foam? Right? Would this make a difference?
Finally (and sorry!) a little change of topic here… what is your opinion about latex pillows? is worth it?
Thanks again!
