PU/Latex/Memory Foam Mattress

Has anyone put together a mattress with PU base, latex in the middle, and memory foam on top? I was laying on a Simmons ComforPedic the other day with this configuration. It felt like Temperpedic support laying in it, but it didn’t have that hard feel when you roll over or sit on it – it actually had a little spring to it. When I was looking at it in a showroom, I was able to see some of the specs on the sheet the sales person was holding:

    Top layer: 4.5” 5.5lb memory foam – ILD unknown, but possibly 2 different foam ILDs (springs back faster than Temperpedic)
    Middle layer: 2" 24 ILD latex (said it was to dissipate heat)
    Bottom: 7" 30 ILD foam (I'm assuming it's PU, but I'm not sure???)

From what I've been reading about foam lately, I thought a combination like this would be too soft, but it was really supportive. After laying in it for awhile, it did seem a lot cooler and more comfortable than a Temperpedic. The price for the above configuration was $4200. Any ideas on putting one together for a lot cheaper?

Conventional wisdom says that's a lot of memory foam. Add 2" of soft latex under that, and you have a really soft mattress. I don't know first hand how that would be to sleep on. 3.5" is about the maximum amount of memory foam I have seen on any mattress. 3" is often recommended for side sleepers, 2" for back sleepers.

I wasn't paying attention, but 5.5 lb memory foam is what FoamByMail is selling. Sensus has occasionally been described as 5.3 lb or even 5.5 lb, but Foamex themselves call it a 5 lb foam.

You don't need 7" of PU foam on the bottom. That's a couple of inches more than you need, unless you just want a thick mattress for aesthetic reasons.

That's my opinion. Few things are carved in stone when it comes to mattresses.

Steve, was this (Mystere) the one you were looking at? Did you try the other ones? It looks like they offer different thicknesses of memo foam and latex.

My guess is that Simmons is using a memory foam that's made specifically for them by Foamex. Foamex already makes a special foam for Sleep-Aid that falls somewhere in between Aerus and Sensus. Foamex has been doing this long enough that they can make about anything a company the size of Simmons would want.

Let me throw out the name Perfection Mattress. The composition of their mattress is not specifically stated on their website, but when I talked to Lee (the owner) some weeks ago, it was 6" of natural Sri Lankan latex with 3" of Venus memory foam. It's the only mattress I know of using Venus foam, and it uses a whopping 3" of it.

That's the one. It is a little thicker than than other ones. I think the next one down has 3.5" of memory foam. 4.5" of memory foam seems like way too much, but you don't sink in too far - it's different. Simmons resently bought this line from another company, so it would probably be tough to say where the memory foam comes from.

Well, if it was a small company bought by Simmons, then I doubt they had Foamex custom-make a foam. So..

1. 4lb foam

2. Open cell structure

3. Slower than regular memory foam

4. Patented chamber process

= Aerus

Steve, did you try the other (thinner) mattresses? Were they not plush enough?

I did, and they were fine. I actually need something around 12" for aesthetic reasons. Let's just say it wasn't my idea to buy taller than normal nightstands to complement height of the bed I have now.

If it's 4 lb foam then I agree.

I don't know how small Comfor-Pedic was in relation to Sleep-Aid, which does sell memory foam custom made for them by Foamex.

3. Did you mean to say Faster?

Ooops, I did mean to say faster. Also, now that I look at the original post, it says 5.5lb...so who know.

I found this info: Comfor-Pedic™* is a division of I/R Foam, a 60 yr. old company out of Washington. Their mattresses utilize a little over 3 1/2" of memory foam in combination with underlying layers of latex. These mattresses have a feel all their own.

Beware that many if not most of these "buyer's guides" have a hidden agenda of promoting a particular product. On the page you linked, notice how only two brands are mentioned by name, Tempur-Pedic and Comfor-Pedic. On the FAQ page they just happen to mention three features of the Comfor-Pedic product - at least 3.5" of memory foam, edge support, and a latex layer, which deftly eliminates one of the two brands mentioned by name on the other page. The reader is left with one choice - Comfor-Pedic.

According to this link Chuck Harmon, owner of the aformentioned domain name, is a part owner of the Tahoe Mattress Company, which just happens to sell...Comfor-Pedic.

How about this one: whatsthebest-mattress.org - self-proclaimed "The Web's Non-Profit Consumer Advocacy Site". It's nothing more than an ad for SAT beds, equating their name with the "name brand" mattresses" DUX, Boyd, Natura, Tempur-Pedic, Select Comfort.

As consumers we just have to stay one step ahead of this marketing slight-of-hand.
