Hi Moose0721,
I’m not sure exactly which bush you believe I am beating around or why you believe I would even want to. I guess I assumed you had read the beginning of this thread (specifically the first 6 posts) where I posted this information and how I arrived at my estimate of the densities in the iComfort mattresses. The early part of this thread also mentions that the gel memory foam itself is not unique to Serta but that Serta was using a higher density than others like the Sleep Innovations novaform gel memory foam. I would also think that it would be up to Serta to post information about the materials they used rather than having people like me or others try to “estimate” them based on the limited information that was available.
I also assumed that you had read the information on my site that suggested that the very fact that a mattress manufacturer is not transparent about the materials they use in a mattress is enough reason to avoid them. If you don’t share these opinions … then by all means ignore them :). If you personally or through other sources you may know or have knowledge of have access to information which is more accurate than anything I have posted … then I would encourage you to post it here. This would be a valuable service to anyone who reads this thread.
I have no control over which parts of this thread or this site you choose to either read or bypass and I also have no issues with how you calculate value, what you believe, or what you end up choosing to buy. Anyone is welcome to use the information on this site in any way they choose.
I notice as well that the Koolcomfort memory foam used in the iComfort is now listed on some sites as being 5 lbs density. If this is accurate … then this is a step in the right direction even though this is not listed on the Serta site itself. Also if this is the case … then perhaps the actual density of the Gel Foam and the memory foam it is added to might also be listed at some point to save people from having to guess or calculate it indirectly. Perhaps you could ask Serta about this with the same “intensity” as you are questioning (and/or ignoring or mischaracterizing) the information you are reading here?
Regardless of any of this though … the bigger issue is about people buying mattresses which are based on having to jump through these kinds of “information hoops” in the first place and on the methods the major players in the industry use to avoid real transparency and avoid giving people ways to make meaningful comparisons between different mattresses and materials.
There is lots of information on the site about the Tempurpedic … and if you choose to go in that direction you will at least have the comfort and assurance of using a known quality material even if the price and value is not comparable to many other choices you may have.
I have talked with “John” at memoryfoamdirect some time ago and while the layering of their Dream mattresses is similar to the cloud luxe in terms of foam density and layering … they are also using Chinese memory foam of unknown origin. Their “testing” does not include any testing for chemicals in the mattress or VOC offgassing. Their Classic series is also identical to the Novosbed even down to the fact that both of them are using unknown Chinese memory foam of the same density and layering.
Regarding getting a 2-3" Serta memory foam topper for $1000 … that would be overpaying to say the least since you can buy a 2.5" Serta gel memory foam topper for less than a third of this at Amazon. This would still be way to much memory foam however if you put this on top of a mattress which already had 4" of memory foam in it.
The Serta gel memory foam is manufactured by Advanced Urethane Technologies which is part of Sleep Innovations. Both Serta and Sleep Innovations have a license to use the gel from Edizone (along with many other manufacturers who use it in many different ways).
Hope this helps … and I’m still looking for more bushes to “beat around”
