Hi bravehard,
I have found a dunlopillo matress that consists of 9'' of talalay latex without any other layer-material. From what i have read i got the impression that the more latex in the matress, the better it is.
I'm not sure where you read this but it certainly isn't the case.
Assuming that the materials in a mattress you are considering are durable enough for your body type and meet the
durability guidelines here
relative to your weight range ... the choice between different types and combinations of materials and components or different types of mattresses are more of a preference and a budget choice than a "better/worse" choice (see
this article
). The best way to know which types of materials or mattresses you tend to prefer in general terms will be based on your own local testing or your own personal experience.
Each
mattress category
can include hundreds of different mattresses with a very wide range of different designs, different "feels", different characteristics, and different firmness levels. Every individual layer and component in a mattress (including the cover and any quilting material) will affect the feel and response of every other layer and component both above and below it and the mattress "as a whole" so each mattress category will generally include some mattresses that have a design that will be a good "match" for you in terms of "comfort", firmness, and PPP (Posture and alignment, Pressure relief, and your own Personal preferences) and others that use the same type of materials and components and are in the same category and may be just as durable but have a different design or firmness level that may be completely unsuitable for you to sleep on ... even if it uses the same general type of materials and components.
The thickness of a mattress or the number of layers or the thickness of any individual layers inside it is really just a side effect of the design and the design goals of a mattress and the thickness of any individual layers or the complete mattress is also only one of many variables that can affect the feel and performance of a mattress relative to any particular person (see
post #2 here
) and by itself isn't particularly meaningful (see
post #2 here
). In some cases higher weight ranges (or a higher BMI) will sometimes do better with a mattress that is thicker than lower weight ranges or a lower BMI (see
post #14 here
for more about the effect of thickness) but even this depends more on the specific design and combination of materials in the mattress and on how well your testing or personal experience indicates the mattress "as a whole" matches your specific needs and preferences in terms of comfort, firmness, and PPP than it does on just the thickness itself.
My alternative is to go for a mattress with layers of talalay and coir. It seems more stable as a feeling but which one will be better ? The latter should have some 4'' tatalay and 4'' coir. Any advise? Keep in mind my back pain and that i sleep on my stomach.... Thanks
There is more about the 3 most important parts of the "value" of a mattress purchase in
post #13 here
which can help you make more meaningful quality/value comparisons between mattresses 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 suitability, durability, and all the other 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 hoped for).
Since Talalay latex and Rubberized coir are both durable materials and there would be no concerns with either of them in terms of the durability and useful life of a mattress ... which mattress would be best for you out of the two you mentioned would be the one that your careful testing indicated was the best match for you in terms of comfort, firmness, and PPP along with all the other parts of your personal value equation that are most important to you.
Based on your own comments and assuming that you have done some careful testing on both of them for comfort, firmness, and PPP ... it sounds like you have answered your own question.
