American company made a better product for Canadian market??
Both are manufactured in USA ??
I know the subject to be already the talk, but several company does not compress the foam, is it better or not in terms of quality rather than transport economy.
Select a bed say: The Gold, Platinum and Diamond Tri-Pedic mattresses use a true high resilient (HR) foam base that are unsurpassed in longevity and support. This high quality material should never be compressed for small box shipping like you will find with lesser quality mattresses.
Tempur-Pedic, same thing…
Thanks !

That would depend on how you are defining “better”. Amerisleep used to use 4.5 lb memory foam in their US models so it’s possible that they are selling their old models in Canada and are now using 4 lb memory foam in their US models. In general terms 4.5 lb memory foam would tend to be slightly more durable than 4 lb memory foam but it can also depend on some of the other factors that can affect durability as well since they are fairly close in terms of density (densities aren’t exact and spec tolerances can sometimes vary by +/- 5 - 10% in a batch of foam. There is more about the many variables that can affect the durability and useful life of a mattress relative to different people in post #4 here and the posts it links to.
There is more about the most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful quality/value comparisons between mattresses.
You can read more about Amerisleep and their sister companies and their so called “expert sites” that pose as being independent review sites in post #2 here and the posts it links to. A forum search on Amerisleep (you can just click the link) will bring up will bring up all the forum posts that mention them but as far as I know all the forum members that were considering them ended up purchasing somewhere else except for two (see post #5 here and post #1 here) who both ended up returning their mattress. While they are in a “better than average” value range compared to most mainstream choices … there are also other options available that for most people would be a better quality/value choice.
Compressing a foam for a few weeks during transportation won’t harm most good quality foams but with longer term compression (such as foams or mattresses that are shipped from China or stored compressed for longer periods of time in a warehouse) it certainly can. It’s also true that some foams that are firmer or denser or stiffer aren’t as suitable for compression and in this case they need to be shipped uncompressed with a common carrier rather than through a courier. A mattress manufacturer will generally work with their foam manufacturer to make sure that they are using foams that are suitable for the shipping methods they use.
