Diamonds in Mattresses! Cool?

Every company looks for something unique about their product to tout in advertising. And that even applies to beds. Take the case of some Simmons Beautyrest mattresses.

They claim that they have infused diamond dust into a layer of their high-end memory foam mattresses in order to draw heat away from the bed, as explained in this video:

And a famed local furniture seller in the Boston area is even doing a commercial touting the amazing benefits of this mattress:

In a Q&A meant for dealers, the company says that diamond-dust-infused memory foam does not breath better than their regular memory foam:

Does Micro Diamond Infused AirCool Memory Foam breathe better or help regulate temperature better than regular AirCool Memory Foam?

While it does not breathe better, it performs better in the overall regulation of temperature. It conducts heat away from the body providing for a more comfortable sleep environment. The thermal conductivity of diamonds tops that of even the best conductors, like copper. In fact, a diamond’s ability as a thermal conductor is four times better than copper. Therefore, more and more diamonds are being used in applications to extract heat. One great example is with electronic devices, which allows them to be even smaller and more powerful.

The company says they put up to 500 carats of diamond dust in certain mattresses. That is the equivalent of just 3.5 ounces. To put that small amount of powder into perspective, a Beautyrest queen mattress is about 143 pounds according to Sears.

But where exactly do they put this diamond dust? It is in one of the memory foam layers, but the company refused to tell us where that layer was located within the mattress. Most mattresses today are made up of many layers of different materials, such as this generic Beautyrest Black cutaway illustration:


MrConsumer is no scientist, but if the diamond-dust-infused layer is not on top, it seems that it would be incapable of sucking heat out of your body and then moving it away from the surface on which you are lying. And since you are not lying on a sheet of solid diamonds, it is inexplicable how flecks of diamonds, not even touching one another, can conduct heat away from anything.

We asked the company to provide us with a copy of any research tests they conducted that would substantiate their claims, what the temperature difference is with and without diamond dust in the mattress, and as mentioned above, where exactly is the diamond-dust-infused layer located.


A PR person for the company called to say that she could not provide test results for competitive reasons, saying that the information was proprietary.

Without this information, it is impossible to judge whether the company’s claims are true… but MrConsumer has his doubts.

  1. Not only that, but in all likelihood you will cover the mattress with some sort of mattress cover/pad. This makes it even less likely that this diamond dust in the mattress would have any benefit. If by some strange chance there actually is some benefit to this perhaps it would make more sense for it to be infused into a mattress cover or the sheets rather than the mattress itself.

  2. The relative area of the diamonds would not make a significant different in temperature regulation. It’s fun when Mr. Consumer is able to use basic science to refute manufacture claims.

    We don’t even need to reach the math or fine print before shunning this ridiculous diamond mattress stuff. Manufacturers are trying to find every avenue to decrease their diamond overstock.

  3. so who is to blame? The manufacturer, the spokesman Eliot, Berkshire Hathaway and maybe even Warren Buffet.

  4. “Extract heat” away from my body? In winter, Mr. Barnum? Ever considered removing a blanket? What’re you, crazy? Oh, ‘yes, like a fox?’

  5. 3.5 ounces is all you need right?? All you need to jack up the price by a couple hundred bucks while only spending a few bucks in materials.

    I highly doubt this so called dust even costs much at all.

  6. Richard is correct regarding the cost of the dust. Diamonds and coal are one and the same – carbon. While high gem grade diamonds command the highest price, the lesser low quality commercial grade especially those used in drill bits for the mining industry are the least expensive. No doubt that the diamond dust falls in this category.

  7. Well my first search for bulk diamond grit (about what they probably would be using here) is .01-.06 cents per carot. 1 kilogram is the smallest they want to sell it at. So 5000 carots in 1 kilogram according to google. So 50 dollars to 300 depending on how much you buy. Not a bad ROI and it sounds snazzy but does nothing.
