Hi Bmore,
[quote]I tried doing some searching and reading for this, but couldn’t find specific posts: any ever tried putting a topper over memory foam?
I’m just wondering if there is a less intrusive approach than surgery, just in case it doesn’t work out and I do need to try to sell.
We could just go buy her a less soft topper and see if sleeping on that would help. But if it’s on the memory foam, will that be a waste of time? [/quote]
There really aren’t any great ways to firm up a mattress that is too soft because a firmer topper on top of softer comfort layers underneath it will usually just follow any soft spots or impressions in the layers underneath it and this can sometimes even make any alignment issues worse and can also create a separate pressure relief issues in addition to any alignment issues that may already exist. There is more information about mattresses that are either too soft or have developed soft spots or impressions in post #4 here that may be helpful.
Adding a topper on top of memory foam can reduce the amount of body heat that reaches the memory foam which in turn can firm up the memory foam or at least slow down the time it takes to become softer. The specific effect will depend on the type of topper and on the type of memory foam under the topper and its temperature sensitivity, firmness, and response time.
