Hi rcseisland,
Just as a general comment ā¦ when you are posting on a forum then using all capitals is considered to be the equivalent of āshoutingā when you are using your voice and itās easier to read if you donāt use all capitals.
Iām sorry to hear that your mattress didnāt turn out to be the best match for you and that you are sleeping too hot but there may be several things you can do to resolve your issues without having to purchase a whole new mattress.
I would also make sure that youāve read the mattress shopping tutorial here which has all the basic information, steps, and guidelines that you will need to make the best possible choice.
The first issue you are having is sleeping temperature and there is some information in post #2 here and the post it links to that may help you track down the most likely reasons why or if there is anything you can do that may be helpful. In many cases ā¦ changing your mattress protector or the type of sheets you use can make a significant difference in sleeping temperature.
The question of the firmness of your mattress is a little more difficult because the best option would depend on whether your mattress is too soft or too firm for you. Based on your comments I would guess that it may be too firm and some of the suggestions in post #2 here may be helpful but only you can really know this based on your sleeping experience.
The specs of the Nature are listed here and as you can see the top two layers are 2" of 21 ILD Talalay and then 2" of 28 ILD Talalay which are a little softer than the 3" of 28 ILD Talalay that is in your mattress (along with the softer polyfoam quilting layer). If the Nature is a good match for you in terms of PPP then it may be worth considering a latex topper that can add some additional softness and pressure relief to your mattress. Post #2 here and the topper guidelines it links to has more about choosing a topper that may be helpful.
If your mattress is too soft then a topper wouldnāt be nearly as helpful because adding a topper isnāt a particularly effective way to firm up a mattress that is too soft (see post #4 here).
If you spend 15 or 20 minutes carefully testing a mattress in a store using the testing guidelines in the tutorial post then the odds are high that most people would make a choice that was in the range that was suitable for them and was āclose enoughā to their ideal that only minor fine tuning would be necessary (see post #4 here).
Having said that ā¦ if you are not confident that your testing will be āclose enoughā to your actual sleeping experience then the return or exchange policies that are available to you after a purchase would also become a much more important part of the āvalueā of a mattress purchase and your own personal value equation and of course I would trust your ābest judgementā about the importance of a return and/or exchange policy.
Both of these use high quality materials and neither one has any weak links in their design in terms of durability but once again ā¦ your own testing or experience will be the most reliable way to know whether either one is a good match for you in terms of PPP and if you arenāt confident about this then I would pay significant attention to the options you have available after a purchase. There is also more about the differences between the āfeelā of Talalay and Dunlop in post #7 here but this would be a preference choice much more than a ābetter/worseā choice. There is also more about the most important parts of the āvalueā of a mattress purchase in post #13 here that can also help you make more meaningful comparisons between mattresses.
There is more about buying a mattress from big box stores like Costco or Sams Club in post #4 here. While they generally arenāt the best quality/value choices for most people and they are not particularly good at providing good guidance about their mattresses ā¦ they do have a good return policy so if you roll the dice with one of their mattresses and it doesnāt work out for you then at least you have the benefit of being able to return it and starting all over again. There is also more about the American Dream Organic (which is the Innomax White Night) in post #2 here and post #4 here and it would be one of the better quality/value options at Sams Club.
Having said that ā¦ the tutorial post also includes a link to a list of the members here that make or sell latex mattresses that include different types of latex (including Dunlop), and have a wide range of different designs, features, options, and price ranges. Many of these are component mattresses that allow you to rearrange or exchange layers to change the comfort/pressure relief or support/alignment of the mattress after a purchase without having to return it and some of them also have a great return policy as well if the āworst caseā happens and none of the options that are available turn out to be suitable for you. For most people these would be in a better value range than an āall or nothingā choice such as the American Dream latex mattress but of course once you are down to finalists that are all between āgood and goodā and there are no clear winners between them then the final choice that is best for you will depend on ābest judgementā and on all the objective, subjective, and intangible criteria that are most important to you.

. Thank you for your detailed reply. I have read, printed and reread your email and all the links. So, yesterday, I spent over 2 hours at the mattress store. I brought 2 pillows and a blanket and spent quite a while on the PLB Nature. I also spent about 30 minutes on a very soft PLB model called Worldās Best Bed, which felt good on my side but bad on my back. I tried a few Serta iComfortās (with very cooling memory foam) as well. Iām still not 100% confident that the Nature is going to work and I will go back in the next few days and spend some more time before a final decision is made. I did find the Nature more comfortable using a $100 PLB latex pillow than my own latex pillow. I think it was a little softer and higher. Part of the problem is that my shoulder and hip was a little sore to begin with. The salesman was very nice and said that I was in alignment but Iām not sure. I also have a Dreamfoam Ultimate Dreams twin (level eight) in my guest room and I slept on it last night. It is better than the 6 but still not perfect, and very hot.
