Hi Shazb0t,
I saw that you had mentioned it in another part of your post but it wasn’t one of the ones you mentioned in this sentence about two others that felt good to you …
… so I was thinking that you may have thought it was somehow a “lesser” choice than the two you mentioned here. Based on your comments though it seems that the F/M/S is a serious contender so your final choices are down to three. In either case your own personal testing and “best judgement” would be the only way to choose and as I mentioned if you can’t tell the difference between them then I would lean towards the firmer of two versions that feel the same to you.
Once you are down to final choices between “good and good” (which you are) and there are no clear winners then the only way to make a final choice (see post #2 here) between two mattresses would be based on all the objective, subjective, and intangible factors of your personal value equation that are most important to you.
@dn,
Based on my conversations with Neal I’m guessing that when they are suggesting firmer latex in the bottom two layers for reasons of weight or suitability then they normally suggest the 100% natural because the firmest versions of the synthetic aren’t as durable with higher weights (that would require firmer support layers) and don’t have the same “feel”. They don’t use the firmest versions of the 100% synthetic in their mattresses because it seems mountaintop hasn’t “perfected” it yet and they believe 100% natural is a better choice (Note: Spindle is now only using 100% natural continuous pour Dunlop in their mattresses).
