Hi Susanbrooklyn,
SleepEZ provides a choice between 100% natural Talalay, 100% natural Dunlop and blended Talalay latex. Organic Dunlop isn’t one of their regular choices although they can supply it as an option on request for those people that are only willing to consider certified organic Dunlop latex.
Most (although certainly not all) people that are looking for an “organic” mattress are usually concerned more with “safety” than whether the latex has an organic certification. There is more information about the three different levels of organic certifications in post #2 here and some of the benefits of an organic certification in post #3 here and there is more about the different types of organic and safety certifications in post #2 here and more about some of the differences between organic and safety certifications in post #2 here that can help you decide whether an organic certification is important to you for environmental, social, or personal reasons or whether a “safety” certification is enough.
There is more information about the different types and blends of latex in post #6 here and there is also more about some of the differences between Talalay and Dunlop in post #7 here.
All of the latex you are likely to encounter (either Dunlop or Talalay that is made with either natural or synthetic rubber or a blend of both) will have a reliable safety certification such as Oeko-Tex, Eco-Institut, or Greenguard Gold and based on actual testing I would consider any type or blend of latex to be a very “safe” material in terms of harmful substances and VOC’s. If certified organic latex is important to you then some 100% natural Dunlop latex has an organic certification but there isn’t any 100% natural Talalay latex that has an organic certification. There is more about organic certified Dunlop latex in post #6 here.
While I can certainly help with “how” to choose … It’s not possible to make specific suggestions or recommendations for either a mattress, manufacturers/retailers, or combinations of materials or components because the first “rule” of mattress shopping is to always remember that you are the only one that can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved that are unique to each person to use a formula or for anyone to be able to predict or make a specific suggestion or recommendation about which mattress or combination of materials and components or which type of mattress would be the best “match” for you in terms of “comfort”, firmness, or PPP or how a mattress will “feel” to you or compare to another mattress based on specs (either yours or a mattress), sleeping positions, health conditions, or “theory at a distance” that can possibly be more reliable than your own careful testing (hopefully using the testing guidelines in step 4 of the tutorial) or your own personal sleeping experience (see mattress firmness/comfort levels in post #2 here).
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 any exchange/return options you have available after a purchase just in case your choice doesn’t turn out as well as you hoped for).
When you can’t test a mattress in person then the most reliable source of guidance is always a more detailed phone conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart and who can help “talk you through” the specifics of their mattresses and the properties and “feel” of the materials they are using (fast or slow response, resilience, firmness etc) and the options they have available that may be the best “match” for you based on the information you provide them, any local testing you have done or mattresses you have slept on and liked or other mattresses you are considering that they are familiar with, and the “averages” of other customers that are similar to you. They will know more about “matching” their specific mattress designs and firmness levels to different body types, sleeping positions, and preferences (or to other mattresses that they are familiar with) than anyone else.
I would keep in mind that there are no “standard” definitions or consensus of opinions for firmness ratings and different manufacturers can rate their mattresses very differently than others so a mattress that one manufacturer rates as being a specific firmness could be rated very differently by another manufacturer. Different people can also have very different perceptions of firmness and softness compared to others as well and a mattress that feels firm for one person can feel like “medium” for someone else or even “soft” for someone else (or vice versa) depending on their body type, sleeping style, physiology, their frame of reference based on what they are used to, and their individual sensitivity and perceptions. There are also different types of firmness and softness that different people may be sensitive to that can affect how they “rate” a mattress as well (see post #15 here) so different people can also have very different opinions on how two mattresses compare in terms of firmness and some people may rate one mattress as being firmer than another and someone else may rate them the other way around. This is all relative and very subjective and is as much an art as a science.
The thickness of a mattress or the number or thickness of any individual layers inside it is really just a side effect of the design and the design goals of a mattress and is also only one of many variables that can affect the feel and performance of a mattress relative to any particular person 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 (or mattress/topper combination) “as a whole” matches your specific needs and preferences in terms of comfort, firmness, and PPP than it does on just the thickness itself.
Latex in general is the most durable of all the foam materials (memory foam, polyfoam, latex foam) and any all latex mattress that is a good match for you in terms of comfort, firmness, and PPP would be a very durable choice regardless of the thickness.
SleepEZ and My Green Mattress are both members of this site which means that I think very highly of them and that I believe they both compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency.
The same mattress (along with many others) is available on their own site.
Like any all latex mattress it would certainly be a durable choice and if after you have talked with SleepEZ you are confident that it would be a good “match” for you in terms of comfort, firmness, and PPP (and/or you are comfortable with the return/exchange options available after a purchase) and it compares well to your other finalists based on all the other parts of your personal value equation that are most important to you then it would certainly be well worth considering.
While you are certainly looking at some great quality/value choices … if you wish to broaden the online options you are considering then the mattress shopping tutorial includes a link to a list of the members here that sell mattresses online (in the optional online step) and many of them also sell latex and latex hybrid mattresses that use different types and blends of latex (including 100% natural Talalay and Dunlop and certified organic Dunlop) that have a wide range of different designs, options, features, return and exchange policies, and prices. Post #3 here also includes a list of online manufacturers that sell component latex mattresses as well.
If you let me know your city or zip code I’d also be happy to let you know about any of the better options or possibilities I’m aware of in your area.
