Talalay vs Dunlop Topper Questions?

[phoenix]

Hi Nemix,

I’ve read on this very forum that generally a 24iLD Dunlop topper would be firmer than a 28 ilD Talalay topper and that Dunlop generally gets firmer than Talalay the more you sink into it,

In terms of firmness they would probably be fairly similar in most cases. You’re right that Dunlop does have a higher compression modulus (the rate that a material becomes firmer with deeper compression) than Talalay.

1. How would a 20 iLD Dunlop topper compare to a 28 iLD Talalay topper if terms of firmness?

Assuming that the ILD is correct … the 20 ILD Dunlop would probably feel softer.

2. Would 28 iLD be considered soft Talalay and less durable than Dunlop @ 20 iLD?

28 would be more in a medium range although firmness is very subjective and relative to the person and what feels softer for one person can feel firmer to someone else.

2. Would 28 iLD be considered soft Talalay and less durable than Dunlop @ 20 iLD?

No … since firmness is also a factor in durability the firmer Talalay may be more durable than the softer Dunlop but again there would be many variables involved.

3. Does the performance of a Latex topper diminished if bought and not used over a long period of time (90 - 180 days)?

No

4. Generally how heavy is a 2" Latex topper?

It would depend on the type and the size and the firmness of the latex. Talalay is lighter than Dunlop, 100% natural rubber is heavier than synthetic rubber, and firmer latex is heavier than softer latex. You can see some examples of the density of blended Talalay and 100% natural Dunlop in post #2 here that you can use to calculate the weight (a king size 2" topper would be 7 cubic feet which you can multiply by the density). 100% natural Talalay would be heavier than the blended numbers that are listed there but lighter than the 100% natural Dunlop.
