Latex layering question

[phoenix]

Hi Bamm98,

I am glad to hear that you are one step closer to fine tune and find the best combination that works for you, and I agree that it is best to take some time with each change and give enough time for the body to adjust.

I am to the point now, I think the wife and I can not sleep directly on latex. I think it is the “pushback” feeling which is making it uncomfortable. I still think I will probably need to try the Aerus Plus 5lb MF topper. Not sure to order the 2 inch or 3 inch. This would be placed over the 28 / combi-coil set up.

Some people do not like the more resilient and “pushback” feel of latex and prefer the less supportive feel of memory foam this is one of those variables that are completely dependent on your preferences. There’s nothing wrong with not liking either latex as regardless of the level of quality of componentry, if you don’t like the feel of a particular material, it doesn’t matter how good that material might be.

The Aerus Plus 5lb MF topper is certainly a good quality and more durable choice. Adding 2" memory foam on top will give just a bit change in the comfort and add some surface plushness while 3" of MF will give a little more moderate change in the surface comfort because the Memory foam will be more point elastic and not so resilient as latex and you will tend to go more through to the layers below than you would with a latex layer. Keep in mind that with the Memory Foam (which does not have the resilience of latex) quite often to achieve a softer surface modification you would need a little bit more material then you would need from a corresponding layer of latex to achieve the same effect in plushness (e.g. if 2" of latex are needed to achieve a moderate softness then to achieve the same moderate softness you would need about 3" of MF)

If I were to go 2 inch MF, I think I am leaning towards getting a good quality 1 inch polyfoam to make up the difference in height. I would need to decide whether to place the polyfoam under the MF or under the 28. I think I would need a medium density polyfoam if placed under the MF and a higher density if placed under the 28.

I don’t know if you came across this reading on our site but It is good to recall that for polyfoam density and firmness are not directly related while density and durability are strongly related and whether you place the polyfoam layer in the upper part of the bed or in the lower part of the bed it would be best to choose a high density (not “medium density”) good quality polyfoam. You can have a soft layer of high density polyurethane such as the newer generation of the high performance polyfoam. The Energex is a high quality polyfoam, one of the newer generation of what I term high performance" polyfoams
The closer the polyfoam layer will be placed towards the upper part of the mattress the more will be influencing the comfort and lend it’s qualities to the layer above.

The configuration 2" MF + 1" polyfoam + 3" (28 ILD) with the polyfoam layer between the MF and latex will of course will keep you furthest away from the feeling of latex that you are not enjoying. It would make sense in this configuration to get a softer high density 3lb polyfoam such as Energex (or one of the new generations of high performance polyfoams out on the market)

Going with the 2" MF + 3" (28 ILD) + 1" polyfoam, and placing the polyfoam under the latex of course it will have less of an impact on comfort and with the latex just under the MF will allow for its qualities to blead more into the MF layer above. Based on your description and desire to keep away from the latex and the more resilient feeling of it then probably the best configuration would be to place the poly in-between the MF and Latex. Regardless if the polyfoam goes under or beneath the latex you still need to have a good quality higher density polyfoam layer.

I’m looking forward to finding out what you end up deciding …
