I just read back to last year and saw you are having problems with your foam being to soft. I also had that problem. My fat ....... body would just sink into the foam and then i was sleeping on wood in a foam lined hole and very hard to move about. So this year I replace my foam with this.
Nice foam
I used the 5 inch thick but only enough for the upper 2 thirds of the bed. Leaving my feet on my old cheap crap foam. This is working much better for me even if it is now a bit to hard but it is not to bad. I slept in it for 10 days during Burning Man this summer. I would say that it is a bit hard, there is one that is not as hard. I used the 5 inch stuff, I could probably use 3 inch and not tell the difference, leaving a bit for a soft 1 inch foam, or just live with it.
I am 5 foot 9 inch tall and weigh 280.
Laying on the foam I doubt if I sink in more than one 1 inch, probably less, setting on it I don't go down over 1/2 way, this stuff is firm. So firm they could barely compress it even a little bit for shipping. That box looked like it was about explode.
So if you go this rout take that in to account. And my feet/legs don't know they are getting the cheap stuff.
