Two-Sided Latex + Pocketed Coils - Huge Sag After 5 Nights?

Hi cwise10,

Thanks for the additional photos. Those are more helpful.

This quilt panel and the pillowtop would be the area where you are getting your “settling”, if I had to hazard a guess. There is definitely something quilted to the cover (this would not be the Dunlop latex), and there may be additional foam as well. You wouldn’t generally get any sort of “settling” with Dunlop of pocketed springs in just a few days. With that being said, what you show seems to be similar to what you would find in settling of a quite plush product, depending upon the tightness of the pillowtop panel (it does seem to be offset on that one side) and the materials being used, especially if they were lower density foams or quite a bit of softer fiber. Using a straightedge would be a better way to measure your dips, as a measuring tape can bow a bit. Assuming that there is some fiber and softer polyfoam in this product, “some” initial settling and body impressions would be considered normal. But without knowing exactly what is in the upper comfort layers of the mattress and being in front of it, I can’t comment in a much more definitive manner.

This would be a “semi-flex” foundation, and even if in good shape I’d tell you to consider replacing it, as after ten years or so there tends to be fatigue in those semi-flex modules and they can sag just a bit. You’d want to keep an eye on yours.

It sounds like you have a good frame under the foundations.

In post #2 here I describe in more detail the use plant based polyols in polyfoam. In a nutshell, part of the polyol portion used to create polyurethane foam is replaced with a plant-based polyol. There’s a brief explanation of this from one of the polyol manufacturers here. The 2.5 lb poly foam would be a good quality material. With the Leggett and Platt spring Quantum spring unit, there are many different designs, and using a thicker gauge steel would generally result in a more supportive unit, but there may also be differences in the zoning, type of pocketed spring and number of springs as well. The spring unit is rarely the “weak link” within the mattress.

The use of a “soy foam” (most polyfoam pourers are replacing part of their petroleum-based polyols with bioh polyols) wouldn’t by itself make the foam better, although it may be that in their case their bioh foam is better than the “standard” that they offer. But a 2.5 lb polyfoam is generally considered a high quality polyfoam.

I can’t speak to the pricing of the product, but you’d want to know of every single layer within the mattress you’re choosing before determining what has the best value for you. While price is certainly important of course … the “value” of a mattress purchase is what is most important and price is just one of many factors that can affect the “value” of a mattress purchase. There isn’t a “formula” that can be used to assess or “calculate” the value of a mattress because there are so many different variables and criteria involved that can affect the price of a mattress that can each be more or less important to some people and not to others who may have completely different criteria or definitions of “value”. The value of a mattress purchase is also relative to how a mattress compares to the other finalists you are considering or to other mattresses that are available to you in your area (or online if you are also considering online options). There are many reasons that a mattress that may be “good value” for one person or in one area of the country may not be good value for someone else that has very different needs and preferences or that lives in a different area.

There is more about the 3 most important parts of the “value” of a mattress purchase in post #13 here which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists based on suitability, durability, and all the other parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).

[quote]I would tell you the brand name of this new setup being proposed (“chiropract…” is included), but I don’t want this to reflect on that company in any negative way. I’ve had a great experience with them so far, and some things are out of their control…especially because this was not made by them (which I just learned today).
Thanks again for all of your help. This forum is the reason I went with the manufacturer I did (and I let them know the same [/quote]

I’m happy that you’ve been treated well and are being allowed to change to a different product.
