Hi PhilOoster,
I switched your post to a new topic of its own since it’s about mattresses that aren’t related to the topic you posted in.
There is more about the 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 all the parts of your personal value equation that are most important to you).
In terms of “comfort” and PPP … this is something that I can’t help with because you are the only one that can feel what you feel on a mattress and the only way to know whether any mattress is a good “match” for you is based on your own careful testing (hopefully using the testing guidelines in the tutorial) or your own personal sleeping experience. Both My Green Mattress and Naturepedic make a range of mattresses that would all be very different from each other so it would be normal that some of them would work well for you and some of them wouldn’t because each person can have very different needs and preferences in a mattress.
Outside of PPP … the most important part of the value of a mattress is it’s durability and a mattress is only as good as its construction and the type and quality/durability of the materials inside it regardless of the name of the manufacturer on the label. If you can find out the information listed here about any mattress you are considering and post it on the forum then I’d certainly be happy to make some comments about the quality and durability of the materials and the mattress as a whole and help you identify any potential weak links in the mattress that could have an effect on durability and the useful life of the mattress. Without this information it’s not possible to make any meaningful comments about the quality or durability of any mattress.
Finally the last part of the “value” of a mattress purchase is how a mattress compares to the other options you are considering based on all the other parts of your personal value equation that are most important to you.
If the Naturepedic mattress you tested was this one then it’s a firm mattress that is made for children so it’s not surprising that it would be too firm and wouldn’t be comfortable for an adult. Some of the other Naturepedic mattresses would be much more suitable for adults although they are also more costly.
