Hi amnj,
With the N3 from Talalay Global, they rate this as an ILD range of 25-30. Conversions of density to ILD aren’t quite as accurate with Dunlop, but 80 kg/M3 is generally considered to be in the upper 20-lower 30 ILD range, and most people would consider the N3 Talalay to be a bit softer than this Dunlop, plus the Dunlop has a higher compression modulus (gets firmer faster with deeper compression).
OLD CONFIGURATIONS/COMMENTS
3" 75, 65, 80 = Slightly too hard, lower back pain no lumbar support + husband had neck/shoulder soreness; but this is very close
2" N3, 65, 80 = Hip flexor soreness similar to when sitting too long, too soft?
N4, 65, 80 = lower back pain
2" 80, 65, 80 = Better but still some lower back pain in the mornings, plus shoulder pain
2" N2, 2" 80, 2" 70, 80 = scrapped the Dunlop65 and tried to go up to Dunlop70 but this still gave me lower back pain and seemed too soft
2" 65, 65, 75 = Too mushy/quicksand feeling
2" 65, 75, 80 = Hip flexor soreness similar to when sitting too long, too soft?
2" N3, 75, 80 = Too mushy/quicksand feeling
2" N2, 2" 80, 80 = started thinking maybe I need more firm so trying no center soft layer, still giving me lower back pain!
2" N3, 75, 85 = Too hard, lower back pain no lumbar support
Going over your previous comments, they really are a bit “all over the map”, and when I see feedback like this it can generally point back to not giving configurations enough time, a poor assessment of the comfort issues, environmental issues (not related to mattress but your state of health, strength, flexibility and sensitivity), or affinity for the substance (latex) being used.
You have some previous inconsistencies where a small change in the deepest support layer takes the mattress from “mushy” to “too hard”, and that wouldn’t be a normal reaction to a small change so deep in the comfort layers, so I agree with you that some of your old perceptions may not be the most accurate assessment of the configurations your tested. There has been a small underlying theme, which I think you’re coming around to, that slightly firmer upper layers are helping out, but you still want some contouring for the hip, which was why I had suggested some Talalay layers on top (perhaps doubling up “medium” Talalay layers), but not the very soft Talalay. I don’t think going with the design of the softer middle layer has been very productive for you, nor has the use of very plush upper layers been positively received in general. Aside from that, I don’t have any specific suggestions besides what I listed above, as I’m unsure (as are you) of the reliability of your previous comments. But sleep ergonomic research will tend to have you lean toward alignment and support, with “just enough” comfort layering to get the job done.
