Upholstery shops have foam suppliers. A good shop will order what you need - or perhaps have a remnant that you can use.
And you want a high ILD foam with a medium density.

A foam with an ILD of about 50 will seem, at first, too firm. However, after sitting for fifteen minutes or more, it is feels still comfortable. And you don't "sink" on it.
Furniture stores don't use a high ILD foam because the lower ILD foams "first feel" is nice and soft. It sells. A high ILD foam would not make a good first impression. (intended)
However, for long term comfort and support, I'd choose a foam with an ILD of 50 (and forget about memory foam and layered sandwich foams. The solution is much simpler.)
It is not all that "cut and dry" to be able to make this kind of statement.
EACH person has a certain level of support requirements which ARE completely DIFFERENT from other people.
There is no "one" set solution to what constitutes a "comfortable" bed which covers "everyone".
Memory Foam does indeed help with a more comfortable bed for those who cannot sleep on a board or rock. Memory foam initially feels hard but you will sink into it slowly until every inch of your body is fully supported. This takes pressure off of areas which tend to get sore like back, hips and such. Memory foam gives you support a bit like an old school water bed without the weight, mess or hassle of a water bed.
There is no magic in memory foam, it simply is a variable density foam vs a single density foam. More expensive than single density foam, sure, but for someone that has joint pain it can help to make an uncomfortable situation a bit more bearable.
Combining memory foam with a layer of firmer foam under it gets you the best of BOTH worlds.
At our sticks and bricks we have an old school Somma water bed (individual tubes), that bed also had a top with a layer of foam above the tubes. Over time that old foam went bad and we replaced it with cool gel memory foam.
Then in our TT we had a custom foam bed made, two inches of memory foam (cool gel didn't exist then) and 4 or 6 inches of 50 IDL foam. For us, it is not nearly as comfortable as our home water bed, the 50 IDL foam is brutally to rock hard by its self but the memory foam does soften it a bit. We went with the 50 IDL because it was warranted longer and was touted to have a much longer life of 10-15 yrs.
With a properly designed foam mattress, you simply do not need any springs or special foundations, those just add cost. And YES, I HAVE used standard spring beds mattreses, I will never go back to them after using a Somma water bed with memory foam or a combo memory foam and regular foam bed..
I know that "Mex" (the OP of this thread) does indeed have many health problems which makes living and sleeping a living nightmare, I am pretty sure that a block of 50 IDL foam is not going to be helpful..
