Firmness Adjustment - New Latex Mattress

[phoenix]

Hi shift_47_,

How much can I expect the latex to soften up, and approximately how long would that take?

There really isn’t any way to quantify it specifically but it will generally soften “a little” over the first 30 - 90 days. A bigger issue though may be the canvas materials in the cover which may also need to stretch and lose some of their initial stiffness and may be interfering to some degree with the ability of the latex to conform to your body contours.

In some cases … shoulder pressure could also indicate a pillow issue and with a mattress that firm you may need a little higher profile pillow to keep your head and neck in good alignment and reduce some of the pressure on your shoulders. There is more about some of the more common symptoms that people experience on a mattress and some of the possible causes for them in post #2 here. For most (but not all) people though in your weight range … a 40 ILD Dunlop top comfort layer would probably be too firm for side sleeping.

If I need to replace the latex to acheive a plusher feel would it be possible to just replace the insert or should I entertain the replacement of the core? Obviously, I would like to soften up the shoulder region and possibly the leg region, but would somehting like a 20/40/20 be too much contrast between sections? Maybe I should look at a softer middle core section, bring it down to around 30 so I dont hit a 40ILD core if I go through the comfort layer?

The upper layers would have the biggest effect on “comfort/pressure relief” and outside of changing your pillow I would first consider using a softer comfort layer. There are also some suggestions in post #2 here for a mattress that is too firm initially and if a top layer replacement isn’t possible then it may also be worth considering a softer topper.
