Yes Mark, it is 2.5".   That is the only thickness I have ever seen in the 5lb.  I don't go to their stores, so not sure if they stock them.

I probably would have gone for 2" if available, but maybe this will be right.   With your current situation, I think this would be too soft for you as a replacement for the Sensus. 

Foamex does not seem to know how to distribute their products.  I don't know why don't they have more options (1",2",3") and possibly 6lb or other densities that supposedly they can make.

Have any input here?  My nose/lungs are fairly sensitive, and I have a personal bias against chemicals in the bed after suffering miserably with a cheap mem foam topper from China.  I wish Essentia's prices were a bit more comparable to the competition!

I also don't get why Foamex doesn't make it more readily available in the higher weights and thicknesses. I saw some places in Canada that still use the Venus 8lb in some of their products but they were mostly medical type applications.

I still suspect that Essentia is using a foam like NuForm and not making their own. I have seen no evidence that they have a factory anywhere.

And talking about Nuform, I just saw that there are toppers available here http://www.mattresses.net/3-inch-rejuvenite-talalay-latex-mattress-topper.html although based on the feedback I had from Sandman when I was asking about it I'm not sure I would use it as a topper.

bed.  Haven't noticed a thing except better sleep.   Of course it is only 1 inch thick.  

Based on the description, I think these are just Talatech (blended) latex toppers.  I don't see an reference to Nuform?
 

Every new piece of memory foam I have tried has some off gassing, this included.  I think this is a little better than average, but still there.   The worst was the gel infused Novaform Costco topper.

Usually it dissipates a fair amount after a few days or weeks and I don't notice it.  However, if you are highly sensitive then it might be an issue. 

I think every memory foam is going to have chemicals, so that is another issue for you.

I guess there's nothing to stop them from putting regular talalay latex in the Rejuvenite pillow or brand but up to now rejuvenite has been Nuform.

He just got them in and he believes that the topper is blended talalay but he read through all the information he had been given with me and none of it said for sure. He said that it did not feel like "slow recovery" latex. The information did use the same wording as the Nuform information but it didn't say anything about what was in it. They call it a "body pillow" (which is probably why it is under the rejuvenite brand). He is sending an email to Latex International to find out. He is carrying this topper because he says it is very nice and has a very nice cover. He usually deals with Radium and has had some problems over the years with LI but he thought this was well worth carrying.

He will email me when he gets his reply.

He shared some other interesting stuff with me as well which I will get to when the opportunity presents itself ... particularly about "organic" mattresses.

I'll post here when he confirms what is in it.

Talatech is theire flagship blended latex.  However, it is possible that the website is wrong.   I don't see any mention of Rejuvenite toppers on the Latex International website.  So, maybe a new product. 

My guess is that it is just the blended latex in a cover.

Phoenix

The rejuvenite site describes it as "RejuveNite™ is a line of ultra-premium talalay latex pillow products. It offers a superior alternative to  products made with "memory foam" and other synthetic materials." which is similar to how LI describes Nuform "Offers a step-up within a latex or hybrid line-up".  It seems that Nuform can be described as Talalay Latex, Ultra premium Talalay latex, Progressive recovery latex, and a few others besides depending on what is seen as effective.

Their press release also only calls it Talalay which is a description for Nuform or Talatech blended or natural.

Curious.

I added 2 mattress pads to try to make it a little firmer (less sinking in).  I put a 100% cotton one that I have over the 3" of latex (pulled tight as I could) to make it a bit firmer below the Aerus .   Then I put the wool Natura one over the wool topper on top of the 5lb. Aerus.

Presto!  a bit firmer feel and less sinking in feeling.  Still pretty good pressure relief and molding to the body.  A bit harder, less plush feel, but that is the tradeoff.

Originally I was going to try with only 2" of latex below, but that felt too hard.  So, at 1am I added back the 1" 24 latex.

I ended up sleeping in until 10:20am.  I can't tell you the last time I did that.  So, maybe I hit on something right.

So, as noted before, little things like mattress pad can make a material difference in feel.  Also, I think it is important to have a pretty firm surface below memory foam if more than 2".   Otherwise, you sink in too far.

Setup below the sheets:   washable wool filled Natura pad,  1.5" organic wool filled cotton topper, 2.5" 5lb. Aeurus memory foam, 100% cotton mattress pad (Sealy brand?),  1" 24ILD 100% natural talalay, 2" 32ILD 100% natural talalay (with softer zone under shoulders),  Sealy Reserved coil system with Sealy 5" box spring.

With 5.5" of foam, I don't think the coil system does that much.  It just provides a base level so support, with a litt bit of give.

I still think I might prefer 2" of the Aerus, but hard to say without trying.  Maybe this is the best I will get without a better coil system.

Yes, the Natura pad does add a bit of firmness to the top layers.

 I even added 1" of 19ILD latex below, and it still seemed firmer.  I did not get noticably hotter using the Sensus (slightly surprising to me).  I have 2 layers of wool and it was a cool night, so maybe not the best test for that.  However, the firmer aspect can help make it cooler - less surrounded by foam.

Right now I prefer the softer, cushier feel of the Aerus vs. the 2" of Sensu.  However, many here seem to like a firmer feel, so the Sensus may work better for most.   Especially those with sensitive backs. 

So far I plan to stick with the Aerus.  No pains so far and less pressure points.  If I had to adjust, I would probably go a little firmer (a little less sinking in).  Options for that are take of the 1" of 24 latex, move the 1" of 24 to the bottom, or put 1" of latex over the Aerus.

 p.s.  I also let the Aerus air out a bit while off my bed.  There is still some odor after 1 week. 

I like the soft cushy feel, but 2.5" is probalby too much.  I would say there is a material difference (support and firmness) between this and the Sensus, even thought they are both made by Foamex and both have 5lb density. 

My gut instinct is that there is some tradeoff between support and breathability.  That makes sense that if you optimize on one variable, you will have to give up on something else.  I know most think memory foam does not provide support, but I think it provides some, because I notice a difference between the different types.

I am going to try with 1" of 19ILD latex over it.  This feels more supportive, but I have not slept on.  I may up returning it, unless I really like it in this configuration. 

I would say that definitely felt a bit more supportive for several hours.  After everything warmed up, I could still feel a fair amount of sinking in.  I could make a little firmer still by taking out the 1" of 24 on the bottom.  I did not notice any back pain in the morning, so it seems like an okay solution.

However, at this point I feel like I am trying to work around a flaw and will probably return the Aerus.  At 2.5" if is too thick for the support it gives me.  It might work for someone lighter or if it was 2" or less.  I think I can fine tune a more supportive and similiar comfort situation with the 1" Sensus and 1" of mem-cool that I already have.

I am coming to the conclusion that they give up something in the support area when they try to make it more open and breathable.  It seems like a fairly tough technology to solve, which is perhaps why Tempur-pedic can charge a premium for a the research they have put into it.

Some companies are experimenting with polyol variations, some with TDI and MDI variations, and some with other technologies (mixtures) leading to differences in heat sensitivity, breathability, ild at the same density, support factor, memory time/resiliency, and others. It is so complex ... and usually proprietary to each company ... that using memory foam in a layering scheme is far more difficult than other materials that are available in a wider range within the same type of foam. Even if you suspect for example that an 8lb memory foam of a certain type (such as Aerus) would solve a certain problem, where do you get it?

I think that a visco manufacturer would do really well to make certain lines of memory foam available in a much wider range of densities and known qualities for those who wanted to customize either their "make your own" or even a commercial "mattress with options". They would probably "capture" a market that nobody seems to be really interested in going after at the moment and I believe would also give Tempurpedic a real run for their money and market leadership position.

I think most of the Tempurpedic is 5.3.  However, some of the higher end mattresses have some higher density layers as well.  I think the Cloud has some less than 5.3. 

Density is not destiny though!  The 5.0 density Sensus seems firmer to me than the 5.0 density Aerus.  So, the feel can vary quite a bit.  Unfortunately, there does not seem to be much data that tells you how it will feel.  My experience has been that the newer "breathable" foams are softer than the less breathable ones.  I guess that is the compromise.  If you like soft and are not too heavy, than the 5.0 Aerus is pretty nice.  I probably would use it, if was not as thick.

Yes, I have seen that.  At the 12lb.s they list the queen size at, it is 3.0lb density.  So, I personally rule it out on that basis.  I assume it would not last as long and probably be even less supportive than the 5lb.

I probalby would have kept the 5lb if it were 1.5".  Unfortunately, I have never found it less than 2.5" in the 5lb density.   It does not provide enough support for me to use something that thick.
