Talalay equivelent of a d60 dunlop topper

[Sensei]

Hey Wollford13,

Welcome to the Mattress Forum! :).

Thank you for your post and also thank you to @Manimal and @silverbull for adding some really good information.

This particular subject and be a little confusing and sometimes be very difficult to compare. Just for some background information, Dunlop and Talalay aren’t directly comparable in terms of firmness using only ILD numbers because there are several factors that can affect how soft or firm a mattress (or an individual layer) feels besides just the ILD of the material (see post #4 here ) and Dunlop and Talalay that are the same thickness and ILD won’t feel the same in terms of their firmness for most people because they have a different response curve and compression modulus (how quickly a material becomes firmer as you sink into it more deeply). There is more about the difference between Dunlop and Talalay in post #7 here.

Additionally, the ILD of different materials or different types and blends of latex also aren’t always directly comparable to each other (see post #6 here ) partly because ILD can be measured in different ways and partly because ILD isn’t the only factor that affects the softness or firmness of a material so again using the ILD or other specifications of a particular layer or combination of layers as a reliable indication of how any mattress will “feel” or how firm it will feel to you compared to another mattress with a different combination of layers can sometimes be more misleading than helpful.

The soft talalay topper I am contemplating buying is approximately 4.3 lbs per cubic square foot (20-24 ILD) and the super soft is approximately 3.9 lbs per cubic square foot (14-19 ILD). It cannot be harder than Aripco D60. If it is slightly softer or equivalent to Arpicos D60 I likely would be fine with it, although I still do occasionally wake up with hip pain on this topper.

Do you know if the Talalay manufacturer is Talalay Global or Radium? Both are great, just minor differences in formula and ILd ranges. Some of the data you provided is a bit different than some of my “research / info”.

24ILD was closer to averaging a D60 (3.75lbs/cubic foot) …and 28ILD averaged closer to 4.3lbs (69kg/meter cubed) …this is not public info and can differs between TG and Radium. Just more of info from my notes and interviews w latex people.

Given all this, I agree w other Manimal probably the 24ILD Talalay is the best choice between the two Talalay choices.

Thank you again, and please let me know if you have any more questions.

Thanks
