Hi 70sgirl,

I would hesitate to sleep in a preset “zero g” position for the entire course of the night because you need to be able to change positions over the course of the night to prevent blood pooling and in some cases stiff muscles that have been in the same position for many hours and if you sleep in the preset “zero g” position it makes it much more difficult to change positions . Zero G positions also aren’t suitable for the majority of people who spend any time sleeping on their side. While some people may do well with this position because of certain health conditions that prevent them from sleeping in a flatter position and elevating the legs a little (either with the adjustable or by having a pillow under your knees) can help to decompress and relax the spine … I would test a mattress in the flat position and then use the different positions that are possible with an adjustable bed based on how you feel in any particular position. In other words your body will tell you which position works best for you. You may also find that you do best with different positions (rather than a preset position) on different nights or even at different times of the night.

I think that you would be safe to assume that the Talalay is the blended Talalay from Latex International (now called Talalay Global) which they call “natural” and is actually a more durable material than their “all natural” Talalay (which is 100% natural rubber) … in the lower ILD’s especially.

I would also keep in mind that these are “finished” mattress with tape edged covers and that most manufacturers can’t just change the components or do custom builds based on individual customer’s requests because this may require that the mattress needs to go through a whole new testing process to pass the fire regulations and most wholesale manufacturers aren’t set up to make custom mattresses based on individual customer requests. In the large majority of cases if a retailer has 5 different all latex models on the floor in different firmness levels then most people would find that one of them would be a suitable choice and would be “inside the range” of their comfort and support needs. Having more models than this may not be something that most retailers would consider because of floor space limitations and because it wouldn’t be necessary for “most” of their customers.

If you are looking for a component latex mattress then you would need to purchase this type of mattress from a manufacturer or retailer that has this type of mattress available because it’s not as simple to change one mattress into another type of mattress completely as you may think. There is more about “finished mattresses” that have glued layers and a tape edged cover vs component mattresses with unglued layers and zip covers in post #15 here and post #2 here. One certainly isn’t “better” than the other and there are pros and cons to every mattress design.

If a mattress has several layers of latex glued together then it would “in effect” be one solid piece even though it began with individual layers that are different firmness levels. If a mattress is all latex from top to bottom and all the layers are the same type and blend of latex then it wouldn’t be important to know the specific firmness of each individual layer because it wouldn’t provide any information that would be useful to you either in terms of PPP or in terms of durability.

You may be getting overinvolved with “comfort specs” that really aren’t relevant to choosing the best mattress for you. ILD is just one measure of the softness or firmness of a foam layer and is a “comfort spec” and not a “quality spec” and is just one of the specs that affects how soft or firm a specific material or layer in a mattress feels by itself. When you are testing a mattress locally then the ILD of the layers isn’t important to know because with careful testing your body will tell you much more about whether a mattress “as a whole” is a suitable “match” for you in terms of PPP than the ILD of the individual layers and ILD itself is also only one of several factors or “specs” that will determine how soft or firm a layer or a mattress will feel to different people and can sometimes be more misleading than helpful (see post #4 here).

For reference the individual layers of the PLB mattresses are listed in post #2 here but knowing the ILD of the individual layers really won’t tell you anything about whether any mattress is a suitable choice for you in terms of PPP. If I was a retailer I wouldn’t sell that way either since I would only be encouraging a customer to make choices based on information that wasn’t meaningful to them instead of doing some careful testing and letting their body tell them which mattress is the best choice for them.

The “specs” you “need” to know are the specs that affect the durability and useful life of a mattress which are listed in this article and don’t include ILD information.

I’m glad that you didn’t consider this because as you know from your reading here the major brands tend to use lower quality materials than I would consider … especially in this budget range … and they won’t be able to provide you with the specs that you really do need to know rather than the ones you don’t (see the guidelines here).

Thanks for the heads up. I’ve removed them from the list.
