Advice on new mattress that I'm considering, please.

Hi scubamom,

I don’t think there is any doubt that the reasons for the issues you have been having are in the foundation.

We now have the Tempurpedic foundations under the PLB Beautiful - they appear to be solid - some sort of fiber board on top and with the knee test, it didn’t give much.

As you mentioned they are made from fiberboard and they are certainly strong and solid with no flex. The only down side is that they have a solid surface which limits airflow under the mattress (see post #10 here).

Now that it is on a firm, flat base, the mattress seems confused… it is still holding the same ridge hump and sagging centers on each side, but maybe it will relax in a few days. Meanwhile, I didn’t relax last night… it doesn’t feel like it did the first 6 weeks when we loved it… still feels out of sorts. My hips seem to be resting on concrete and no matter how I move, it doesn’t have the nice support and pressure relief it did back then.

There is no doubt that the Tempurpedic foundation will change the feel of your mattress compared even to your defective foundation when it was new (your mattress would have been sagging into the gaps from the beginning even if there were no visible sags).

The latex itself shouldn’t be damaged but the layers may have shifted or bunched because of the defective foundation underneath it. I would give things a week or two to see if it “recovers” and evens out again. I would also make sure you sleep on the parts with the ridges as much as possible.

I would also email PLB with your pictures and a description of the issues you have been having (and I would also include that your retailer has been having trouble getting them to return calls) and ask them about the options you have available if your mattress doesn’t recover in a week or two.
