What is "Smartlatex"?

Does anyone on this forum happen to know what "smartlatex" really is? Just curious why they don't just call it latex. Must be synthetic?

Any help deciphering this buzzword would be appreciated! Myself, I'd prefer it if they'd call a spade a spade, and quit giving things names like "smartlatex." Between that and all the other marvelous undefined enhancements being touted in the mattress industry, like they're supposed to mean something and that we're supposed to know what they mean, I'm getting the shudders. I'm about ready to make my own mattress out of straw.

OK - I have a follow-up question if anyone knows....Jim? Budgy? To get the two-layer solution euphemistically called "smart latex," do they have to use some kind of adhesive? Or would those two layers naturally bond by being poured one on top of the other? I ask, because I've had the experience of making lemon meringue pie, where once the layers bonded (I think due to combining them when the heat was appropriate for both layesr, and another time when they just kept completely separate. I can imagine two layers of different latex composition might tend to separate, unless the process was closely controlled, or unless some kind of adhesive was used.

I'll tell you this right now - I'm not in love with the idea of breathing in adhesive fumes all night....

Hi, I have not examined the smart latex pieces so I cannot say for sure. But I was told by Sealy that it is poured as one piece and the assumption is that it bonds together without glue. I am quite sure that is what they told me, but as to whether or not it's true, I cannot say for sure. I can't imagine they would glue them together, as that much glue would be counter to the feel of the latex. When glue dries on latex it creates a hard crusty surface. Again, according to Sealy, the layer is poured as if one piece of latex, no adhesive needed. You might try calling a Sealy representative in your area. Each region or state has a Sealy rep who services the mattress stores in his region. Theoretically you could get this number from a helpful sales person. I'm sure they don't give it out to just anyone but if you explain that it's just a simple question you have, you should be able to get the answer from a Sealy rep. Don't believe the mattress sales person, they often either don't know or will just pretend to know. No offense to mattress sales people, I know some are honest but the fact is many are liars and I can prove that with my own experience with them.

ive never seen a sample of the stuff so its hard to say.  latex itself is an adhesive....but how they would cure (vulcanize) two different densities in the same mould makes no sense to me...unless they partially fill a mould and cure one firmness on the bottom, then fill the rest of the mould to do the other layer which probably would bond itself to the piece underneath....but why they would do this I really do not know.  sounds like a waste of time and a reason to just promote their product being somehow different (and of course better) than the rest.

Thanks, Jim and Budgy! I appreciate your insights! I don't see what the advantage is supposed to be over just stacking two layers of different density together. It probably is just an advertising gimmick. Just calling it "smartlatex" I guess is supposed to make us assume it's a great new innovation or it would be called "smart," would it?  Doh!

I agree that whatever it is, it's mostly just marketing. The mattress industry is full of it (pun intended).
Putting 2 layers on top of each other without gluing them would achieve the same thing in my opinion.

I saw a page describing Simmons foams. It has about 30 different types of foams with different names. Or was it Sealy/S&F? Whatever, they're all pretty much the same when it comes to marketing. Anyway, what it boils down to is that 99% of these foams are just PU polyurethane foams of various ILD's, some with convoluted tops, some zoned, etc and all the fancy names sound very scientific and attractive. But they're just different names for crappy PU foam!

In this case, "smart latex" is just another name for a synthetic latex foam, imho.
