Hi jege41,
yes … I have talked with Literie Laurier on several occasions about their Costco topper and other things as well. They are good people.
You can see in post #1 here and my reply that there was another member who thought that their Costco topper was impressing or too soft but it seemed clear to me that it was more about the softness of the mattress/topper combination and that he was sinking in too far for his body type and sleeping style. While it’s unlikely that the topper has an impression issue … you can find out for certain by putting it on a flat hard surface like the floor and then measuring the depth of any impression with a string or straight edge.
I thought the most effective way to deal with Costco’s description was to call Literie Laurier because they have been good people to deal with in my experience and have been very responsive and are aware of this site. They get their Talalay latex from a distributor in Montreal rather than directly from latex International.
So I talked with Francois there and he confirmed (and even went to the warehouse to check) that they only use blended Talalay latex not the natural because like me they believe it is more durable and that the extra cost of the all natural isn’t usually justified (at least based on performance). The description on the Costco site apparently originates from their supplier who may have made a mistake and used the description of another type of latex they sell so he will track down where it originated and let me know.
In the meantime … it’s clear to me and to him that you received 28 ILD blended Talalay which is a very durable material and not generally subject to the kind of impressions you are experiencing. I think the odds are very high any soft spots you are feeling are not likely to be in the topper itself … although of course anything is possible.
