High resilience foam questions

[phoenix]

Hi David2469,

Thank you, I will look over that. With all that being said, I have a Boyd Natural Flex 920 . My first is an all foam mattress and about a year is all that foam seems to be good for. I took it apart only to find ( IT IS NOT MADE AS IT SAID ) it has 1" on bottom then two 4" layers and 2" on top. It was supposed to have ( 3 layers total with 3" on top )

The layers that the Natural Flex 920 is “supposed” to have are listed here.

If the layers in your mattress are different from this I would consider calling either your retailer and/or Boyd to find out why (or whether you received the correct mattress). I would also be aware that all the layers of this mattress are polyfoam including the “engineered latex” (see post #11 here) and with a mattress like this I would always make sure that you know the density of all the polyfoam layers before a purchase so you can make sure that there are no obvious weak links in the mattress and make more meaningful comparisons to other mattresses.

I removed the top and put 4" super soft on the bottom and flipped it the encasement. Thinking I needed softer. foambymail super soft broke down in one week. softer where butt was. I flipped it over again and am sleeping on the 4" whatever that is under thier so called engineered latex. it was for awhile but now hurting again LOL. So all in all I figured I could put quality foam in place of this crap.

I would also 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 from FBM or considering them as a reliable supplier.
