Hi Wendy1107,
Foam by Mail doesn’t sell Talalay latex (even though they say they do).
I would be very cautious in dealing with Foam by Mail (FBM) or any of their other websites including Foam Factory, USA Foam, Foam Distributing, and others. I would make sure you read more about them in post #2 here and post #2 here and in this thread before making a purchase there.
