Hi SleeplessinDallas,
I’m sorry to hear that once again a mattress that you were very hopeful about didn’t turn out to be as good a “match” for you as you hoped for over the longer term. The only “good” news that I can see is that you have always had some attraction to the Tempurpedic brand and perhaps your experience has helped you to realize that there is certainly no “magic” in the Tempurpedic name (see my earlier reply to you in post #2 here which I have often used as a reference post in my replies about Tempurpedic to many other forum members).
There is more information about some of the reasons that a mattress may feel different at home than it does in the store in post #39 here but outside of actual differences in the mattresses the ones that are most likely would be either be differences in the break in and adjustment period, the sheets and bedding or mattress protector you are using vs the mattress in the store which would be a “bare” mattress, or any differences in temperature or humidity either in your bedroom over time or compared to the temperature and humidity in the store (memory foam is sensitive to both temperature and humidity).
Just for reference … the specs of the Tempurpedic Flex Supreme Breeze (from the Jordans webpage here which is the only site I know of that lists the specifics of their Tempurpedic mattresses) is as follows …
Quilt: Tempur Breeze Cooling Cover with PCM
Comfort Layers:
2" Tempur-ES 4.0 LB density memory foam
1" Tempur-Climate 5.3 LB memory foam
Bottom Upholstery(below comfort layers):
2.5" 1.6LB Poly foam
Support System:
17 gauge twice tempured pocket coils … Twin 840 coils, Full 1260 coils, Queen 1610 coils, King 2070 coils
Full perimeter foam encasement (foam density unknown)
There is more information in post #9 here about the different ways that one mattress can “match” or “approximate” another one. Every layer and component in a mattress (including the cover and any quilting materials) will affect the feel and performance of every other layer and component and the mattress “as a whole” so unless you are able to find another mattress that uses exactly the same type of materials, components, cover and quilting, layer thicknesses, layer firmnesses, and overall design (which would be very unlikely) then there really isn’t a reliable way to match one mattress to another one in terms of “comfort”, firmness, and PPP (Posture and alignment, Pressure relief, and your Personal preferences) based on the specifications of the mattresses (even assuming that you can find out all the specifications you would need for both mattresses you are comparing in the first place).
Mattress manufacturers generally try to differentiate their mattress from the mattresses made by other manufacturers and don’t normally try to “match” another mattress that is made by a different manufacturer so unless a manufacturer specifically says in their description of a mattress that one of their mattresses in the same general category is specifically designed to “match” or “approximate” another one in terms of firmness or “feel” and PPP and/or they are very familiar with both mattresses and can provide reliable guidance about how they compare based on the “averages” of a larger group of people that have compared them (different people may have very different opinions about how two mattresses compare) … the only reliable way to know for certain how two mattresses would compare for you in terms of how they “feel” or in terms of firmness or PPP (regardless of anyone else’s opinions of how they compare which may be different from your own) would be based on your own careful testing or actual sleeping experience on both of them.
Off the top of my head I also don’t know of any other manufacturer that makes a mattress that they specifically describe as being a reasonable approximation of the Tempurpedic Flex Supreme Breeze so if you are using it as your “target” or “reference point” then you would need to make comparisons with other mattresses based on some trial and error with your own careful testing of local mattresses or your own personal experience when you sleep on a mattress that you weren’t able to test before a purchase.
If you are looking at online options that you can’t test in person before a purchase then the most reliable source of guidance is always a more detailed phone conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart and who can help “talk you through” the specifics of their mattresses and the properties and “feel” of the materials they are using (fast or slow response, resilience, firmness etc) and the options they have available that may be the best “match” for you based on the information you provide them, any local testing you have done or mattresses you have slept on and liked or other mattresses you are considering that they are familiar with, and the “averages” of other customers that are similar to you. They will know more about “matching” their specific mattress designs and firmness levels to different body types, sleeping positions, and preferences (or to other mattresses that they are familiar with) than anyone else.
You could also look for mattresses that has “somewhat similar” layers and components with similar specs and similar properties and hope for the best but again it would be very unlikely that you would find another mattress with the same specs and even if you did some of the specs that they don’t list may result in a mattress that has layers and components that “appear” to be similar but have a different feel or firmness level because of the many possible differences in specific materials and components that can’t be predicted based on only knowing a few of the specs for each of the materials or components in the mattress.
I would also be very cautious about using a specific mattress as a “target” or “reference point” unless you are open to buying that specific mattress because it may not be the “best” match for you in the first place in terms of “comfort”, firmness, and PPP compared to other mattresses that you haven’t tried yet and you could end up excluding many other mattresses that may be similar (or even quite different) but may be a better choice for you in terms of PPP. In other words … I would rate every mattress you consider against a common set of criteria based on suitability, durability, and all the other parts of your personal value equation that are most important to you rather than rating them based on how similar they may be to your memory of another mattress that you tried and liked.
