Mattress comfort layers - latex

Hi Sensei,

I didn’t realize there is a density difference between NR and blended talalay. Just knew about dunlop vs talalay.

Discovered why my 19 blended softened after only 2 nights. Received my ticking and was surprised at how much that tightened the mattress up, even though it’s just stretchy knit cotton, no wool. Rotated the layer and have slept on it for 4 or 5 nights. The side I’m on now has changed little, the other side still feels slightly softer. So I guess I learned a way to speed the break-in of latex - take the cover off!

Hi Kim68,

Welcome to the Mattress Forum! :).

Thank you so much for your questions, and well done with all the research and contacting the companies and asking questions. Of course, as you have probably read on here, only you and your husband will be the only ones to be able to decide what is best for you both. It is really a combination of all the factors in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists based on all the parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hope).

All of the mattresses listed are of high quality and high-quality materials. Regarding an all talalay mattress, I think it is a very good alternative and no reason why you should not consider it. It is very common for many manufacturers to offer Dunlop Latex as the “core” and Talalay latex as comfort layers. I say this in very general terms as many people have been very happy on “all talalay” latex mattresses…usually cost is the major reason people buy and many companies “offer” Dunlop and Talalay mixed.

Regarding the Talalay mix of 12 inches of latex, I would use Xfirm for both bottom layers, still no problem using top two layers of Firm/Med or Med/Soft for “softer” side.

The other two recommendations are solid, the only thing I would caution, is that for higher BMI customers, you may be receiving “firmer” recommendations, but you know that you like something a bit softer.

You have a good group of solid choices from three of our trusted members, so you are on the right track. Please let us know if you have any other questions.

Thanks again for posting with us.

Hey lotus14,

Thanks for that update, and it does make sense that “breaking in” would be quicker without cover. And it is always amazing for people doing DIY latex mattresses…totally different feel with a cover. Regardless of the weight of cover, the feel will always firm up when covering the latex layers. Good stuff thanks for the update.

Hi Kim68,

Another trusted member who can make any split configuration you want is Sleeping Organic.

I found their advice regarding layers to be very good. They were really easy to work with, shipped quickly, and in general were a good company to business with.

Hey lotus14,

Thanks for the note on Sleeping Organic, always nice to have a consumer put a good word in for recommendations to another consumer. I totally agree with you also.

Thanks
Sensei

Hello,

I have a blended Talalay latex topper in 3 inch 19 ild over a 28ild blended talalay latex topper over Leggett and Pratt pocket coils. After about a month it felt like it flattened out and did not relieve pressure points or properly support my back anymore. I got it from Arizona premium mattress. I am 5’11 and weigh 170. I have been switching the configurations around because it is not comfortable anymore and causing me back pain. The 28ild topper Is not as flattened out as the soft one is, which may just be normal softening. Is that normal for the 19ild topper? I didn’t think I weighed too much for the soft topper. I have read that the synthetic is not as elastic as natural latex, but this seems unusual. Is it possible it could be defective? Has anyone else had this experience? Is this happening because it is blended latex and not natural? I really liked the initial feel of the soft latex. I also checked the foundation of the bed to make sure it was level, the slats are 2 inch apart. I even laid on just the pocket coils and there is no issues with those, it is definitely the latex.

Any suggestions??

I am very interested to hear what the experts have to say. I’m having a similar problem - my blended talalay is softening at an alarming rate.

Sensei mentioned in another thread that blended is less dense than 100% NR. Related?

The interesting thing is that manufacturers say that blended is actually more durable than NR, especially at lower ILDs.

Hey lotus14 and mnn4532,

I am not sure I can really add a lot to this conversation.

As I read both of these situations, I think we are talking about different things. The 19ILD talalay blended topper is one of the best selling toppers in all the latex business, so I think it is entirely appropriate for many people and there is not an “overall problem with 19 ild blended latex”.

For you mnn4532, you have posted this issue several times, and I am sorry it is not working out for you. Statistically speaking, I usually do not think its a “quality of foam” issue, like softening too much. But it is not to say that it could be an issue with that particular core of foam, making it break down too fast, just no way to tell. I think that this combination is not the right fit for you and your particular needs. I am not saying I have the right answer, only you can determine what you need to go on top of the leggett coils.

Lotus. of course “rapid softening” does make me concerned, but still it is really hard to tell, wasn’t this the topper w/o a tag? Which doesn’t mean its 2nd quality, only curious if it was averaging closer to 17 than 19…just a thought.

Sorry if I can’t bring any closure for you, but it does seem you will need to try a higher density topper to get you the right mix of support and pressure relief.

Thanks
Sensei

Thanks Sensei,

Good to hear that 19 ILD blended is so common and rare to have a problem with.

Yes, it’s the same w/o tag 19 ILD blended. Perhaps I’m just surprised at the change in feel. It’s more like the air goes out of whichever side I sleep on for a few days even with (an admittedly lite) cover, hence the feeling of losing support. It’s probably just normal settling.

It IS on top of 24, then 28 talalay. Perhaps it just doesn’t have enough support from underneath. I know some sellers use all talalay, but most of the recommendations I’ve gotten strongly suggest dunlop for the base layers. Sleeping Organic REALLY wanted me to use dunlop for the bottom two.

Perhaps I just need to exchange the 24 for a 36, 28, 19 setup? Sleep EZ suggested 38, 31, 20 with at least the base as dunlop. When I suggested 31, 31, 20 to them they strongly suggested both 31s as dunlop.

If I have to I could go with Arizona’s thin but much stronger cotton/wool cover as well though I really like the feel of the thin, stretchy knit cotton I’m on.

That’s Interesting, my toppers also do not have tags on the them, just 19 and 28 written in marker. I guess I will have to just try something else, thanks for your reply.

As Sensei pointed out in another thread, the tags are often not present because the layers are split, so likely unrelated.

I’m going to give it a little more time. If the 19 I have continues to feel like the air is going out of it rapidly, I may switch to Sleep EZ’s Radium talalay. Just hate to spend the money and effort to return these layers when I really don’t know there’s anything wrong with them. Could be just normal settling but I don’t want to find out it’s not months down the road.

Edit: Ok apparently 19 ILD Talalay is the next step down in softness from 20 ILD Dunlop, so I’ll give that a try first before 14 ILD Talalay.

Hello, I would like to know if 14 ILD Blended Talalay topper will be as soft as memory foam? The feel will obviously be different, but just want to know if it will sink as much.

I bought a puregreen medium firmness mattress from amazon that has 6" 34 ILD dunlop with 2" 20 ILD dunlop on top. I’m a side sleeper with wide shoulders and I woke up with sore shoulders every morning. I tried adding another 2" of 20 ILD dunlop, but that didn’t really help. Recently, I tried 2" memory on top, and it was perfect in terms of pressure relief. No more sore shoulder! The only problem is it sleeps warm, and now I wake up sweating. I’m thinking of giving 2" of 14 ILD Blended Talalay from mayersbedding a try. Will this be closer to the memory foam topper and softer than the 20 ILD dunlop? Many thanks!

Hey comp666,

Welcome to the Mattress Forum! :). Thanks for the post.

I am going to answer a couple of things then give you some background links that may explain things better.

The short answer is yes the 14ild will most likley feel softer, but its more complicated than that. Also 19ILD Talalay will not reallly feel similar to the 20ILD Dunlop latex, more info on both of these points below and in associated links. I think 19ILD talalay is good choice to try for your particular situation.

Latex and memory foam are very different materials and can’t really be meaningfully compared to each other. You can read more about this at this post #2 here.

Latex is highly resilient, has a more “on the mattress” feel to it, and responds to pressure. What you feel on latex stays the same over time. You can read more about the pros and cons of latex in this article and more about the different types and blends of latex in post #6 here.

Also, what was the density / ild / brand of the memory foam you tried?

Another point, even though latex is “cooler” than memory foam, generally speaking…putting a plush talalay topper on mattress can sometimes “feel” hot becasue the latex envelops your body, thus covering more surface area…leading some people to love the feel but still be a bit too hot. Just FYI so you know going into it.

Thanks again, and please don’t hesitate to ask any other questions you may have.

2" thick, 3 pound density, by Sure2Sleep on Amazon.

mayersbedding recommended me 3" 19 ILD blended talalay topper for a 175 lb male so that’s what I ordered. Hope it works!

Here’s one interesting thing I found today when I decided to take some pictures of my back when side sleeping. My spine/legs/neck formed the straight line, commonly found in mattress ads (cough purple), with both the 2" 20 ILD dunlop topper AND the 2" memory foam. Despite this, the dunlop causes more pressure on my shoulders. If I stacked the 2" Dunlop on top of the 2" memory foam, my hips sagged into the mattress, breaking the straight line. I can see how playing with mattresses can be an interesting hobby!

Hey comp666,

Thanks for the update, 2" 3lb memory foam. I like the 3" 19ild Talalay recommendation. Now you will have a 3lb memory foam topper, Talalay and dunlop…a basic representation of most “mattress toppers”…really interesting about the pic of alignment of body.

Uh oh…hobby…or rabbit hole?

Is copper infused talalay as comfortable and as durable as it would be if the copper were not infused?

Hi Kerra,

Thanks for the post. The short answer is yes it is just as comfortable and just as durable. The Talalay process is a very robust process, and it has proven to keep all of its benefits with the additives the Talalay companies have tried over the years…graphite, copper, FR chemicals, etc. Now, that is not to say that some chemists can find some minor differences in durability and loss of height between formulas, but generally speaking, it will feel very much the same to most consumers

All the latex you are likely to encounter is a good and durable material. The addition of copper used as a filler (such as TGs “Talalay mineral”) is generally used to improve the processability and heat transfer (due to the increased surface area) of the PCM. The benefits of Cu used as a filler in both memory foam and latex are more connected with its thermo-conductive properties and even though copper infused latex is advertised as having side “health benefits” (such as copper bracelets) to my knowledge these benefits have not been proven in copper infused foams. The main benefit for adding Cu to latex or memory foams would be for thermal conductivity (which generally is not an issue with latex, to begin with) so I personally would not make a priority to choose one over the other (with or without copper).

I hope this helps you in your search:)

First time poster here…the site has been a wealth of information and helped me end my year long search for a new mattress, but now I need to tweak the comfort layer.
In March we purchased a one piece king PLB nutrition mattress, it sits on an adjustable frame. I am a side sleeper, 5.4 ft and 150lb. My husband is primarily a back sleeper due to sleep apnea and using a cpap machine, he is 6ft and 225lb.
I have back issues and can only sleep on my back if on an incline, usually about 3 am my husband removes the cpap and then will roll to his side.
After a couple of weeks of the mattress alone I could not side sleep due to sore hips and knee pain.
At this point I purchased the 2 inch soft PLB topper, while it’s helped I still have some pressure points…in hindsight maybe I should have gotten the 3 inch. Now I am wanting to add another inch of latex, either on top of the 2 inch or directly under it.
I emailed Mayer’s bedding and inquired about the soft 20-24 ILD Talalay, based on my size he recommended that would work as a medium soft, or go with the super soft if I wanted more plush. I have briefly thought about the blended but then I read on this page that some people had issues with the blended being too soft.
So now I am trying to choose on the non blended. Will the 20-24 ILD under the 14 still have some softness and still keep my posture in line or is 1 inch under the soft not going to have any impact ? So many options and I am struggling to make the choice.
I wanted to add for my husband he could literally sleep on cinder blocks or a marshmallow bed and it would all feel the same to him .
Thanks for any input and sorry for the super long post.

Hi Britexmom,

Welcome to our mattress forum :).

Great post, thanks for sending.

I am very familiar w the PLB nutrition, high quality but not surprising you need to tweak the comfort layers.

“Will the 20-24 ILD under the 14 still have some softness and still keep my posture in line or is 1 inch under the soft not going to have any impact ?”

The 20-24 ild under will have some softness and will help keep you posture in line but your instinct on 1 inch losing some impact is true to some extent. Generally speaking the firmer comfort layers below softer are usually the same or greater height.

Question - The 14 ild soft plb topper is blended, correct?

The 20-24 ild you may buy is Talalay 100% natural?

You may want to consider a 2" 20-24 just to be safe, but only you know of this is necessary.

Also the natural Talalay is bit more dense when one compares same ild blended vs. natural. But the 24 ild blended will work below the 14ild you are already on.

Let me know of you have any other questions.

Thanks
Sensei

Thank you for your response. I am not sure if the topper I already have is blended or not, to be honest I just purchased it because it was the same company who made the bed. Would it say somewhere on the topper ?
So a 2 inch blended topper of 24 ILD might be a good option to go with, the blended is cheaper than the natural so the extra inch wouldn’t cost quite so much.
Would it be worth considering a Dunlop layer or is it best to stick to the Talalay for one of the comfort layers.
