Hi Sleepless in bflo,
That would really depend on the specifics of all the materials and components in each mattress you were comparing and on the “organic” criteria that were most important to you or on how you define organic. I think that Cozy Pure puts a little more emphasis on having all natural or organic materials and components in every part of their mattress (down to the thread used in the cover) because this is their specialty and they also put more emphasis into “green” manufacturing (using alternative sources of electricity) and only use natural or organic materials in their factory but the only way to know with any certainty would be to compare every material and component used in the two mattresses you are comparing.
They also have different designs and options in their mattresses so which one would be the best choice for you would really depend on everything that was part of each mattress purchase, how you feel about buying locally vs online, return or exchange policies, and on all the other parts of your personal value equation that are most important for you.
Once you are down to final choices between “good and good” and there are no clear winners it usually ends up depending on smaller differences between them and on which one you are most comfortable dealing with and purchasing from for reasons that are unique to you.
I think highly of both of them.
