Hi tempured mad,
You can see my comments about their latex topper in post #2 here. I don’t believe it’s Talalay latex. Of course any type of latex is still a good quality product but mostly synthetic Dunlop latex (which is what I believe it is) is a much lower cost version of latex than 100% natural Talalay which they claim it is.
Other than the suggestions in the previous post I linked … post #4 here includes a list of the better and most reliable online sources for toppers that I’m aware of.
