Hi khackett7,
Welcome to the Mattress Forum!.
I’m not sure if TD-Max will see your post since the last post in this topic is over 3 years old and TD-Max hasn’t been to the forum in about two years.
Having said that … I’m pretty sure that all 4 of his layers were blended Talalay latex.
I would also keep in mind that that the type or blend of latex is more of a preference and budget choice than a “better/worse” choice and his preferences may be different from yours. There is also more about some of the general differences between Talalay and Dunlop latex in post #7 here but the best way to know which type and blend of latex you tend to prefer will be based on your own testing or your own personal experience.
