You are right, the original post was all 2" layers = 10", however we exchanged that one for the 4"firm, 2"med, 2"soft, 2soft" and it was perfect. So one 4" core plus three 2" comfort layers.

General questions, Does it matter which side of the latex foam is facing up? I usually see the smooth side up not the rough side. If I see a large air bubble hole on side of a piece of latex foam, should I be concerned?

Talalay latex tends to be quite consistent top to bottom, so if you had a layer slit from the top or bottom of the core it wouldn't tend to feel too different, regardless of orientation. With some Dunlop latex, you can get some settling of the latex particles toward the bottom of the mold, and sometimes pieces slit from the bottom of the core can feel a little firmer than pieces from the top. There would be the potential for more of a difference between layers from the top of a Dunlop core to those take from the bottom of a Dunlop core, but this tends to be small and may not be noticeable to most people, especially if placed in the deeper layers of a mattress. The smoother layer (skin)will usually represent the bottom of a Dunlop mold, so this can represent a bit of a firmer level of that piece of foam. If you're unsure, you can press into the piece of foam from the side near the top and bottom of the piece of foam and see if you notice a difference in the softness. This is less noticeable in 2" layers than a 6" core. Larger bubbles and small voids are normal in latex foam when it is slit from a core and usually not a cause for concern unless they are large enough to create a large void, which would be uncommon.

What do you consider large? The width of a thumb and depth up to knuckle? So smooth or rough on a 2" piece of latex makes no difference?

Hi Phoenix,

I ended up doing a layer exchange and got a firm dunlop layer. I experimented with some different configurations and found that FD, MD, ST, topper seemed to provide the best support, but did not provide enough pressure relief. However, if I remove the ST from the mattress cover and put it outside with the topper, it was excellent and felt like I was sleeping on a cloud, which is the feeling I am trying to achieve. However, my hips are still sinking in a little too far so I'm still having some back pain (although definitely not as much as before).

I found a company that I could order some tensioner slats from, but when I talked to them, they said I would probably not be able to feel the difference with a 10" mattress and 2" topper. So I don't think that will help my hips.

I guess at this point I need to consider a zoned layer? I am allowed one more layer exchange with Sleeping Organic, however I don't think they do zoned layers. I suppose I could exchange for another firmer layer, which would bring my hips up more, but I don't see any scenario where only my hips would come up and not my shoulder too, which would still leave me in the same situation of my hips being too far below my shoulder.

I looked at some of the links you attached and saw your suggestions about using a piece of firm polyfoam under the hips. I think this would be worth trying. Should the polyfoam go under the bottom layer of the mattress or under one of the middle layers?

If I end up wanting to do a zoned mattress, would I need to return my current mattress and buy a new one from Flo-beds, or could I just purchase one zoned layer from Flo-beds to add to my current mattress?

Hi oad8730.

. if I remove the ST from the mattress cover and put it outside with the topper, it was excellent and felt like I was sleeping on a cloud, which is the feeling I am trying to achieve.

Glad to hear that you are sleeping better and it looks like you still have a few options to get the best of all worlds.
Nice “out of the box/encasement” solution you found out there. :) All the layers in a mattress interact together and sometimes even seemingly small changes like placing the top layer outside the encasement can change the feel and performance of a mattress quite significantly. The encasement especially when new, will tighten everything up and the mattress will feel firmer than it will feel after some time of use, but the most adjustment you’d tend to notice will come from the fabric covering your mattress and of course that any topper or fitted sheet will also contribute to the overall feel.

. I guess at this point I need to consider a zoned layer? I am allowed one more layer exchange with Sleeping Organic, however I don't think they do zoned layers..


You are correct, Sleeping Organic does not have any zoned latex at this time.

I looked at some of the links you attached and saw your suggestions about using a piece of firm polyfoam under the hips. I think this would be worth trying. Should the polyfoam go under the bottom layer of the mattress or under one of the middle layers?


Closer to the skin the polyfoam layer is placed the more it will be felt and you can experiment with how each of them feels to you. If you feel that your hips are sinking in too deeply, then bring the polyfoam layer a little closer to the top. If it turns out that this is a deeper alignment issue, than you can place the poly closer to support core.

If I end up wanting to do a zoned mattress, would I need to return my current mattress and buy a new one from Flo-beds, or could I just purchase one zoned layer from Flo-beds to add to my current mattress?


FlowBeds is one of our "Zoning" Expert member and have a great deal of experience and customer input in this area. I am not sure if they would consider sending you an individualized zoned layer but I suggest that you reach out to them and ask for their advice. They are really happy when they can share what they learned.

Hi - I have been trying to determine whether it is better to avoid pocket coils. Can they emit fumes, attract dust mites, result in mattress changing firmess/shape over time?

Are there any reliable reviews on Cocomat?
They have coconut hair, horse hair and seaweed in their cores well as Dunlop latex.

Hi Lborducci.

Welcome to our Mattress Forum! :)

Hi - I have been trying to determine whether it is better to avoid pocket coils. Can they emit fumes, attract dust mites, result in mattress changing firmess/shape over time?


I would personally not have any concerns with fumes or dust mites originating from a pocket coil. As far as VOCs or odor, the non-woven fabric used to "pocket" the coils is innocuous this is not something that people complain about. While certain products may be dust mite resistant if the food source and environment are appropriate you can get dust mites in any style of mattress. The key would be keeping their main food source (skin cells) to a minimum, and keeping the environment low in humidity (Dust mite population prefers a warm, moist environment that they need to survive)

As far as pocket coils changing firmness/shape over time... all items fatigue over time and a pocket spring unit would not be an exception. Generally, the spring units would not be the weak link within the mattress and you would notice changes much more in the foams in the upper layers because of the mechanical stress they undergo and because in time, with aging, they will gradually lose resiliency and develop impressions. Innersprings tend to hold their shape well (poor quality steel would lead to changes much more than a higher quality steel). Usually firmer latex will be more durable than an innerspring but neither of them would tend to be the weak link of a mattress.

Are there any reliable reviews on Cocomat?


While reviews or other people's experiences can be useful to gauge the reputation of a business, they won't tell you much if anything about the suitability, quality, durability, or "value" of a mattress as it relates to you (see post #13 here ), and I recommend to take them with a grain of salt and to avoid considering them as any sort of a reliable indicator of the appropriateness of any particular product for your needs.

CocoMat mattress components (Dunlop latex, rubberized coir, rubberized horsehair (expensive), seaweed, essential oils, cactus fiber and others) are high quality materials and would meet the quality/durability guidelines. The company focuses on natural premium materials and unusual products and designs. Depending on your personal value equation you would be looking at a much higher price point (we are talking 10K) and firmer overall feel, although they have two firmness choices for some mattresses. Some people like the feel of it while others don’t so it is of course again a matter of preference and your personal value equation. While Coco-mats are not commonly found domestically they recently opened a showroom - Coco-Mat USA in New York, and the mattresses themselves have been around for quite some time.

I hope this helps.
