Hi maverick3934,
There are hundreds of topper sources for hundreds of different types of memory foam (more than I could possibly keep up with) but most of them don’t list the foam pourer that supplies them.
There is a list of DIY sources in post #4 here and some of these are from sources other than FXI. There are also some polyfoam suppliers in the same post that also supply memory foam but you would need to call them and see if they will tell you their sources and of course any information that’s not listed on their websites such as the type and density and whether it is CertiPur certified.
A few other sources that I have on my list that may be worth some calls and some further research to fill in any missing information includes …
