Hi The Biologist,
OMI (Organicpedic) makes some very nice mattresses that use high quality materials but they are certainly not in the best value group compared to many other mattresses that use similar materials.
Some of the better options in the San Francisco Bay area are listed in post #2 here. Some of these sell all latex mattresses that use the same or similar materials but the designs may be quite different and you would need to test them in person to see how they compare to any of the OMI mattresse you tested in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
To know this you would need to find out the specific information about the OMI Lago you tested (layer thickness, type of latex, and ILD of each layer, and the specifics of the cover) and then compare it to the options you have available with SleepEz. If the materials and design and the mattress covers are identical between the two (which is unlikely) then they would be very similar but each difference between them in terms of their design would result in some differences in the mattress that some people may notice more than others.
There may be many mattress designs that use different pathways to a similar outcome in terms of PPP and they may both be equally suitable in terms of Posture and alignment and Pressure relief even though they may be different in terms of “feel” or other preferences that may be important to you.
Once you have the specific details of the materials in the Lago (or Lago Nouveau depending on which one you tested) … then you are ina much better position to talk to other manufacturers to get their thoughts about which of their mattresses may be the closest approximation.
So with local choices, your own personal testing and experience along with having the specifics of the materials inside the mattress will tell you how the mattresses compare. With an online choice that you can’t test in person, then more detailed discussions with the manufacturer (who know more about their mattresses than anyone else) would be the best way to decide on which mattress they offer may be the closest approximation and this may involve some guesswork and intuitive “translations” between designs depending on the amount and degree of any differences between them. Translating from one design to another is more of an art than a science and individual perceptions about how closely two mattresses with different designs match may vary widely between different people.
