Last year we bought a Sam's Club memory foam mattress for our motorhome. It is 8 inches with 3 inches of memory foam on top and a 5 inch base. My husband loves his side but I hate my side as the memory foam is to soft for me. My back hurts every morning when I get up. I feel like i have sunk into a hole. I have put an eggcrate on top of the mattress and then underneath the eggcrate on my side I have added some firm cardboard to help firm it some. It has helped a little but I would like a better solution as after sleeping on it for a couple of weeks the cardboard weakens. Does anyone have any suggestions what I can do on my side to help firm it up some. I have looked for some kind of mattress topper/pad that is firm but have yet to find one. HELP!!!

Thanks in advance for any and all suggestions.... Sheri

You have to get rid of the memory foam. Memory foam softens and when it gets too soft there is nothing you can do about it except get rid of it. You cannot make a bed more firm you can only make a bed softer. This is why anyone in the know always advises: Do not buy a bed with a topper or "pillow top"; instead, buy it firm and add your own topper(s), then when the topper gets too soft you can replace it with a firmer one. Anyway...

How do you deal with this mattress that is too soft on your side?

Well, as I see it you have 2 options.

As I understand it you have a double or Queen or something and your husband likes his side just fine but you don't like your side. So what you have to do is either cut the bed in half or take off the memory foam on just your half.

Either way you will probably require the use of an electric carving knife in order to do it.

Depending on how the memory foam is glued to the top of the "core" or "support" foam under it, you might be able to pul it off, or you might not. If you want to try to pull it off, this is what I would do: I would cut a line down the middle of the mattress, cutting through just the memory foam, right down the middle, vertically. Then see if you can gently pull off the memory foam without it destroying the foam underneath. If it comes off easily, voila! now all you have to do is go out and buy a nice firmer topper and replace it. You may need to cut the topper to make it fit on just your side, but that's why you have the electric carving knife.

If you can NOT tear off the memory foam without destroying the core underneath then you can do this:
Use the same line you drew down the middle vertically and cut through the entire foam, core and topper.
Once it is cut through, just turn it over so you are now sleeping on the core, and the memory foam is now on the bottom. If that is too hard you can add a one or 1 and 1/2 or two inch topper but try to get a medium firm latex topper, or a very firm memory foam topper, maybe a 5lb one or heavier that won't be so soft.

Then if THAT fails, what you can do is go out and buy a piece of HR foam or M-Grade foam the same height as your old mattress, minus however thick of a topper you're going to put on it. Then put that side by side with your husband's side, and it will stay in place. My wife and I have done that for years (2 different mattresses side by side) and we have never had a problem with the 2 foams drifting apart. The friction of the foam tends to keep it in place.

Good luck!
