You can see the ILD range for Latex International's 100% natural Talalay (expressed as N1 - N5) and the target ILD's for their blended Talalay and Talalay GL on their site here . You can also see the ILD range for Radium 100% natural and blended Talalay here .
While knowing the ILD (Indentation Load Deflection) is a good indicator of softness/firmness caution I’d suggest that to not base your decision on the ILD alone. as this accurate only when comparing the same type of latex from the same latex manufacturer. There is also much difference in feel when comparing synthetic, blended latex and 100% natural latex of the same ILDs (see post #6 here ). In addition to this equivalent ILDs from the two Talalay producers, Talalay Global and Radium, also feel different so you can’t make a direct comparison based on ILD. With careful testing your body will tell you much more about whether any specific combination of layers or components or any specific mattress is a good "match" for you in terms of comfort, firmness, and PPP (Posture and alignment, Pressure relief, and your own Personal preferences) than knowing the ILD/IFD of the individual layers regardless of what the actual numbers may be.
I have the Ultimate Hybrid in plush but the coils are too firm as I get hop pain when I sleep on my side. I sleep all over the place. Ken recommended to get a 2 inch topper. I have a thin waterproof mattress protector on the mattress. Do I need to purchase the bamboo cover for the topper or can I just put it under my mattress protector? I am trying to save money if I don't need it. Also, wouldn't a cover make the topper more firm?
Jill71rdh- I'm hoping to see a response to your question as I have basically the same one. I have a 2" latex topper (which is inside its own stretchy encasement fabric). It won't fit inside my current mattress protector so I'm wondering about what kind of protector to use for the topper that won't change the feeling of it. For now I've just put an extra layer of fitted sheet to give a bit more barrier. It seems like anything that would actually be protective wouldn't have enough give to not change the feel of the latex. I have a little bit of hip pressure already and definitely don't want to add to that by firming it up.
Jill - if you find an answer elsewhere would you mind posting back here? Thanks.
Thanks for the question. The short answer is yes you can put a raw latex topper under your existing mattress protector, many people do this and there is nothing wrong, per se with this activity. The latex itself can be torn easily, so one should be careful about this. If raw latex is left out to ultraviolet light, it can break down quicker, but probably not an issue if you put under your protector and leave it there.
Thanks for the question, I am going to give you quick answer then also provide a few links to some other posts from Phoenix on this subject.
There is always a tradeoff between the different functions that a mattress protector is meant to provide. One of these is the degree of water resistance that is important for each person and their circumstances. The second is the effect on the feel and performance of the mattress (thicker less stretchy protectors will affect the mattress more than thinner more stretchy protectors). Finally, there is the effect on temperature regulation and airflow (more airflow and moisture wicking will have less effect on the temperature regulating properties of the mattress than less airflow and less moisture wicking).
For your specific needs, you want to make sure you find a "stretch knit" cover without a waterproof membrane. The stretch knit provides the give and stretch to maintain the feel of a quality latex topper. Pay close attention to the size of the topper you have and the size of the cover as sometimes a very tight fitting cover will firm up the topper a bit too much.
Here is a link to a latex cover post from Phoenix about this subject and also more associated links within this article.
Also here is a quote from a post Phoenix had on 11/12/2018 ( Post link ).
FOR MATTRESS or TOPPER COVERS:
Mattress covers can be one of the most significant parts of the cost of a mattress and also one of the most important. Not only can they have a major influence on how a mattress looks and performs ... cheap or thin mattress covers will not properly protect the foam inside and in particular with latex will allow the foam to degrade and break down much more quickly and significantly lower its longevity. Some of the better sources of zip mattress covers include ...

I have a new question that is similar to the old about a cover. As I stated before, my Ultimate Hybrid in plush (19 ILD I believe) is too firm and it was suggested that I get a 2 inch topper. From Mattresses.net (where I got my mattress), they have a 2 inch blended talalay mattress with a bamboo cover (bought separate). It states it is 19 ILD. I found on another site (flexus comfort) a 100% all natural talalay topper that comes with a cotton cover for about $55 cheaper with their current sale. They state the ILD as being 22. Will there be that much of a difference in the blended 19 ILD to the all natural 22 ILD? What about the covers (bamboo vs cotton)? If I can save myself $55 that would be awesome but I also want to get what is best.
Thanks for the post. Both of these toppers will be really nice Talalay toppers, and regarding the feel, they will feel very similar, the 22ild a bit firmer, and will be bit heavier, and usually more expensive. The covers really the same thing, you can certainly compare cotton bamboo, but they are both stretch-knit quality products from the pictures on the website. Both companies are trusted members, but please make sure you check prices again, as I saw prices as the blended being less expensive than the 100% natural.
