More Topper Questions

Hi Chloe41,

It would probably make the mattress softer because even a firm foam layer would have more give and would be softer than what the mattress is currently resting on (either a foundation or a platform bed). I don’t know how much of the additional softness you would feel though with an additional layer that deep in the mattress where it wouldn’t be compressing very much. The firmer the foam the less likely you would be to feel it but no foam will be as firm as the solid non flexing surface it would be replacing (unless you are using a foundation that has some flex to it).

Probably yes … it would make it softer. There is more about the effects of thicker layers or a thicker mattress in post #14 here.

If you do decide to go in this direction the firmer or more rigid the foam the less effect it will have on the mattress

I don’t know what your mattress is currently resting on but if all you want to do is add some additional height then a rigid non flexing slatted bunkie board (see post #4 here) may be worth considering.
