Hi Kefit,
There is no “formula” that can help someone choose a mattress and there are really only two ways to decide on the design of a mattress that can work best for you. One is with your own careful and objective testing on a specific mattress you are purchasing and the other is a more detailed phone conversation with an online retailer or manufacturer (see mattress firmness/comfort levels in post #2 here).
The first thing I would suggest is to make sure that your testing was similar to the testing guidelines in post #1 here and you tested the mattresses you mentioned for PPP (Posture and alignment, Pressure relief, and Personal preferences). In many cases people confuse support and firmness with spinal alignment and the key for a supportive mattress is that you sink in evenly and your spine is in good alignment in all your sleeping positions. A soft mattress can be just as “supportive” as a firm mattress if you are in good alignment.
The next thing I would do is confirm the layers of the specific mattresses you did best with in terms of PPP. You can see the specs of the Pure Latex Bliss mattresses in post #2 here. They can be useful as a general guideline although all of these are a different design from the mattress you are considering
While the mattresses you tested are not equivalent to the Ultimate Dreams all latex mattress (assuming that’s the one you’re looking at because it’s the only one they have that is all latex which is what you’ve been testing) or even their hybrid mattresses … your testing and any other relevant information about you can can help them give you some suggestions and guidance that can help you “translate” the designs you preferred into the options they have available that may be “somewhat” or most closely comparable. This is as much an art as a science. Again though … this is something that can’t be done in an email or on a forum and needs a phone call and a more detailed and “nuanced” conversation to have the best odds of success.
I sincerely doubt that there is anyone on this or any forum that can give you better guidance about your choices than the help you would have available with a phone call. They have more experience in helping their customers make the best possible choices based on their body type, sleeping style, preferences, and any local testing they have done than anyone.
