Polyurethane Foam

Hi smmimp14,

I don’t think there’s much I can add to my comments in my reply to your previous similar questions in post #2 here.

If you are planning to order from Foambymail (FBM) then I would read this post and this post and this topic (about their polyfoam and sources) and this post (presumably from a past employee) before buying anything or considering them as a reliable supplier.

It’s very unlikely that a 2.8 lb density polyfoam would have a compression modulus of 1.9. Given your past comments as well I would also suggest that a 50 ILD topper would be too firm for you (this is usually used as a very firm support layer not as a comfort layer) and if you only have the choice between these two firmness levels (and assuming that you buy from them at all) then I would lean towards the softer IFD.

In the end the only way you will know whether any topper will “work” for you in combination with a specific mattress (which will be a big part of whether the sleeping system “as a whole” will be a good “match” for you in terms of PPP) will be based on your own personal experience and I would make sure that any topper you purchase has a good exchange/return policy just in case the topper you choose doesn’t work out as well as you hope for.
