Hi Minneaple,
Resilience is defined as the height that a ball dropped on a mattress will return as a percentage of the original height. By this definition Dunlop would be more resilient than Talalay.
Talalay has a higher resilience and is more “springy” or lively than Dunlop because it tends to spring back more strongly and compresses more deeply than Dunlop in the same ILD more so the “up and down” motion may be more. Post #49 here talks a little more about resilience, bounciness, and springiness and post #7 here talks more about the difference in “feel” between the two materials (and also includes the video link that dn provided) but as dn also mentioned the best way to know is through your own personal testing because things like bouncy and springy can be so subjective and will depend on the design of the mattress as well. It really is a preference issue and different designs of latex with different softness/firmness levels in the layers will have a different “bounce” or “springy” feeling. All the layers will contribute to this to some degree.
I think highly of the quality and value of the BE mattresses (NOTE: they are now selling their own similar design … see post #4 here) but they would be a much better source of information about the “feel” of their mattresses than I am. Shipping a mattress through common carrier vs courier can add to the cost of a mattress and it would also be very costly to return it and some of the benefits of them being able to make custom changes after a purchase at a reasonable cost would also be lost so buying one of their mattresses without trying it and having it shipped would be a risky proposition IMO.
There are other latex options in the Minneapolis area listed in post #2 here and i would suggest that your best odds would be to test various types of latex combinations so you can narrow down which type of latex you tend to prefer and if it turns out that your idea would be the most suitable choice based on your testing and preferences then it would certainly seem to be a viable option.
