Mattress Forum

Over a year ago I opened up my mattress and experimented with different configurations using the existing foam. I ended up removing the topmost plush layer (about 1.5 - 2 inches thich) which had the most sag and I put some material between the boxspring and the inner spring to bring the springs back to level (there was less than a one inch sag in the springs, can't remember exactly how much now, maybe 5/8 inch). I had 3 one-inch pieces of PU foam left in the mattress. Mattress felt ok but kinda hard after that (so not great) but now starting to wake up with backaches again (more sagging from the remaining layers) so I'm planning to just replace all the PU foam with latex.

For people who have gone down the path of latex over springs, do you simply lay the latex directly on the springs or do you put something between the springs and the latex so the latex isn't damaged. Right now, the lowest PU foam layer has some kind of white cotton-like feeling material on the underside of it. This is the part that lays on the springs.
