Hi zab,
Thanks for your update.
Congratulations on your new mattress! :cheer:
To be fair to the salespeople you encountered, if you were inquiring about latex, this is most commonly referenced by ILDs and not densities, especially Talalay. If it was for memory foam or polyfoam, if the salespeople didn’t know that information (sometimes it isn’t provided to them) hopefully that is information that they would have been able to find out and get back to you about.
I’m glad you had a nice experience there.
That is logical. Most stores will mention that your new mattress will feel slightly firmer than the floor model because of the “breaking-in” that the floor model has already experienced.
There’s some good information about mattress protectors in post #89 here and this post.
