I have read your info on polyurethane foam and have asked about this before. There is nowhere for me to go and try such an item. I will be brief and hope you can give me a brief and informed answer. I weigh 300 lbs. , yes, me again. I have had a too soft and too firm latex topper, I have had a 2" 5.0 density memory foam topper and a 3" 5.o memory foam topper and I have tried them separately and on top of each other. I am too heavy, They do not support my weight as they should. I was told I need a more dense topper so am considering these options: A HD polyurethane topper 2.8 density, ILD 35, support 1.9 or a HD 2.8 ILD 50, I believe that too has a support of 1.9. I am thinking of a 3" thickness for the first one and am thinking the second will bee too firm. I have called very many places and keep getting different answers. I would be ordering these from one of two locations online, both located outside of Detroit. I just need a simple recommendation as to how these would serve ma as a topper. Hope you can help!!! Thanks.
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.
