Hi dxmichelle,
Thanks for taking the time to post all the Tempurpedic specs in one place. They are in various places around the forum but yours are more complete and easy to access.
The only comment I would make is that these are “old” specs and while they were mostly correct at one point they may not be correct any longer because Tempurpedic has been doing their best to remove any specs about their mattresses from the internet and I have received some some strong indications from what I consider to be reliable sources (plural) that the specs that used to be correct may not be any longer (and they are certainly not providing any updates). As you also mentioned they aren’t providing any information about their newer mattresses which include the Breeze, Float, and Simplicity lines or their new Airbeds. At one point they also published that the polyfoam base layers they were using were 2.2 lbs but this information has disappeared and there are some strong indications that it may now be lower.
There are some general thoughts about the Tempurpedic line and materials in post #10 here.
There is some analysis of the foam densities they use and how it may not be the same as it once was in post #18 here.
There is some information and thoughts about the Tempur-Weightless line and materials in post #8 here and post #2 here.
There is some information and thoughts about the Simplicity line in post #14 here
Some thoughts about the Tempur Breeze mattresses are in post #6 here.
Since they are so new … I haven’t posted any thoughts about their new airbed line although you can read about my general thoughts about airbeds in this article.
Finally you can read some of my thoughts about Tempurpedic and the “Tempurpedic name” in post #2 here.
So once again thank you for taking the time to add all the layering and material information in a single post and your idea of having a “Tempurpedic” specs thread where all the most important information can be together in one place is a great one
