Hi Johnnydm,

Is it fair to say that the memory foam is relieving some pressure in the shoulders? Noticing less crunching of the shoulders with the foam.


Yes ...this would be fair to say. The memory foam layer would certainly help with pressure relief and shoulder scrunching.

I will be making a purchase for 2 inches of 22 ILD Talalay topper to replace the memory foam. I should anticipate this will work better than the older memory foam topper.


I would think so yes. It will be softer and more pressure relieving than the Dunlop that you currently have and increase the pressure relief but it would also be more supportive than "old memory foam" and isolate you a little more from the firmness of the Dunlop layer underneath it. In other words ... it will be more pressure relieving than your current Dunlop but you won't sink through it to the Dunlop layers below it as easily as the memory foam.

I think a firmer base foam should help with the hip and shoulders. Due to finances I may have to purchase some HD or HR Poly foam for now. I was thinking a LUX HQ either 3 or 4 inches?


I would wait with this until after you have purchased the 22 ILD talalay to check how your current layers are working for you. One step at a time is always more accurate. I would also avoid purchasing from Foam By Mail (who sells "Lux" foam which is just their name for polyfoam) and I would never buy any latex from them because the odds are far too high that what you believe you are buying will not be what you actually get. When you end up with "unknown" foam (whether the unknown is the type of foam, the type of latex, or the ILD) ... it makes it impossible to know how to put your layering together. I also don't completely trust their "Lux" foam because their specs don't match the specs that higher density or HR polyfoam should have (particularly with their rating for sag factor). It may be that the specs are listed incorrectly but I wouldn't take the chance with something as important as a mattress that you will be sleeping on for a long time. Perhaps in the bottom layer I would use it if absolutely necessary but even there I personally would have trouble supporting a business that causes more confusion than their prices help ... especially when the small difference in price between them and other polyfoam suppliers that are more accurate and reliable is very small.

Another deal I noticed was a Dunop Tr-Zone 5.5 inches, ILD 31-35-31 and for $349. I realize it is 75% SBR and 25% Rubber. Any experiences about this core layer?


As you probably know I'm not the greatest fan of mostly synthetic Dunlop (natural Dunlop is more elastic) but having said that ... depending on the price and source and someone's budget ... it can be good value.

Hi Phoenix,

Would like to ask you what you think about putting a memory foam layer underneath the top layer of latex.?

I did an experiment of placing a 2 inch memory foam (5 year old sleep inovation foam beigish color) underneath my 2 inch of fim dunlop and than my 3 inchs underneath the memory foam. I noticed just a little stiffness in neck and shoulders however no pain in hips or lower back. I think ideally a slightly softer latex inplace of the 2 medium/firm dunlop should be better.
Now just holding off on a the comfort layer because I may only get 1 inch and purchase a higher quality foam of 2 inches. Thinking of Auerus or Bayer.

Hi johnnydm,

I personally like the feel of some types of Latex/memory foam hybrid layering and it's fairly high up on my list of preferences. Of course as you mentioned ... the trick is to get the combination right in terms of both the softness and type of latex, layer thickness, and type of memory foam as well. In particular ... I liked the feel of the NXG 575 which has a thin layer of latex over a fairly thin 2" layer of memory foam over 3" of latex (all over pocket coils).

Like you I would tend to put a softer latex over the memory foam (and probably thinner as well so you are a little closer to the memory foam).
