Is my latex core failing? 21 Mar 2017 07:39 #1

In 2014 we bought a 6" queen natural dunlop latex "medium" mattress with no comfort layer from Brooklyn Bedding. I wanted to be able to customise the comfort layer separately and thought I was spending my money wisely by investing in a long lasting core, paying for the upgrade to "natural dunlop.". It is now 2017 and there is a feel-able hump in the middle, with troughs on both sides, one deeper than the other because one of us is heavier than the other. The mattress has been regularly rotated but cannot be flipped as the mattress cover is only plush on the top and the core is not accessible separate from the cover.

This mattress is on the floor at the moment as I though our bedframe was failing and needed to verify it was the mattress. The indentation in which I sleep is causing me lots of lower back pain as I am a stomach sleeper.

Should this be happening and how can I measure this deflection?

Hi SoFresh,

Welcome to the Mattress Forum! :)

As I’m not present next to your mattress, it’s not possible for me to make an educated analysis of your product. But I can provide some general information.

You weren’t specific with which model you purchased and the covering used, but I’m assuming it might be the Essence Natural Latex with the 6“ Natural Dunlop core, using the covering with wool quilted to it. It’s also not clear to me if you’re sleeping upon the core with the separate cover for the comfort layers still attached to it, which would be empty per your description. I’m also unaware of the ILD of the latex core you chose.

There will be some gradual softening of any foam, even latex, through the life of the product. There will also be softening of the cover material, so it would be normal for this to be felt in the areas where you sleep and for the foam to feel stiffer and perhaps a bit higher in the area where it is not used as much. You also didn’t mention what you were using for a foundation, and this can contribute to the feel of the product and perhaps contribute to sinking in certain areas.

Without being in front of your mattress, I couldn’t comment upon what part of what you feel might be from the latex core, the covering, the foundation, or a combination of all of these things. The best suggestion I would have would be to contact Brooklyn Bedding directly and explain to them your concerns, and they will have instructions for you on how you can evaluate the product to see if it is deemed to be a warranty issue, or normal softening, or perhaps if there is something else contributing to what you are feeling. If you did purchase the Essence, it came with a 20 year limited warranty, and body impressions over 1.5” are generally considered a defect, provided the mattress was continuously supported on an appropriate solid foundation. All latex will generally be a very durable material (Talalay and Dunlop, synthetic, blended or natural), so excessive body impressions would be unusual, but you do have a good warranty to cover that if you did indeed have a defective product.

Thank you for your response. The cores are "medium" natural dunlop inside a Cotton Camilla polyester cover with fiberfill polyester batting but the words "organic cotton" stitched all over the cover, lol. The mattress tag does not match the contents of the mattress and it describes what I assume would be blended talalay because it says the contents are 65% rethane foam and 35% latex. I am certain the cores are dunlop and can tell the difference.

I have contacted Brooklyn Bedding to get additional info on my order and was told they do not have records that go back that far, so it was incumbent on me to dig up any info I might have. I cannot imagine how they can maintain warranties with records that shallow, but we may find out.

The topper has been removed from the bed as has the "plush" portion of batting that is in the top of the cover and we are sleeping on the core only on the floor, to isolate the fail point.

Hi SoFresh,

Thank you for that information.

The cores are "medium" natural dunlop inside a Cotton Camilla polyester cover with fiberfill polyester batting but the words "organic cotton" stitched all over the cover, lol. The mattress tag does not match the contents of the mattress and it describes what I assume would be blended talalay because it says the contents are 65% rethane foam and 35% latex. I am certain the cores are dunlop and can tell the difference.

What you’ve described is a bit odd, as I don’t know why you would have been shipped a latex core with that cover. The 10” Cotton Camilla was a hybrid latex mattress using a 6” 1.5 lb polyfoam core (one piece). On top of this you could choose from three different comforts of 3” of blended Talalay latex (this is the part you said you chose not to purchase). The cover is 100% organic sourced cotton, and it is quilted to 1” of quilt polyfoam. You can see the information here from the Wayback Machine. If you ordered the 10” Essence, that product had its own zippered cover, so I find it odd that you wouldn’t have been shipped the appropriate cover for the Essence, unless you in fact did order the Camilla.

I have contacted Brooklyn Bedding to get additional info on my order and was told they do not have records that go back that far, so it was incumbent on me to dig up any info I might have. I cannot imagine how they can maintain warranties with records that shallow, but we may find out.

It is always incumbent upon the purchaser to maintain their original sales receipt – that is pretty standard boilerplate for mattress warranties.

The topper has been removed from the bed as has the "plush" portion of batting that is in the top of the cover and we are sleeping on the core only on the floor, to isolate the fail point.

Sleeping with the mattress on the floor will not isolate a fail point, but can point to potential issues with your current foundation (which you didn’t mention what you were using).

If you do indeed have the Camilla, it isn’t surprising that you would feel more of a “broken-in” area sleeping upon simply a 6” polyfoam core without any comfort layers – that makes more sense.

Hopefully, once you find your paperwork, you and BB will be able to figure out exactly what you have.

Thank you so much for linking that way back machine! That helped me tons. It is the Cotton Camilla with a custom dunlop core and no comfort layer. I think they decided on this because I wanted absolutely no polyester/rayon (bamboo or otherwise) in the mattress cover. The salesman incorrectly assured me that there was none.
