Hi B Feelgood,
Mountaintop Foam makes a range of continuous pour Dunlop latex cores that vary from 100% synthetic to 100% natural and are made with 7 zones in each core. They are all high quality and durable materials regardless of the blend. They also come in softer versions than are typical for most Dunlop manufacturers (comparable to the softest Talalay ILD’s).
There is more about the different types and blends of latex in post #6 here but the choice between different types and blends of latex is generally a preference and budget choice rather than a “better/worse” choice. There is also more about how Dunlop compares to Talalay in general terms in post #7 here. The MTF continuous pour Dunlop is somewhat in between the two but would be closer to the feel of Dunlop (continuous pour is a version of the Dunlop process).
Radium and Talalay Global (formerly Latex International) both manufacture the Talalay latex that is used by mattress manufacturers … they don’t supply either the raw materials or equipment that other companies would need to manufacture latex. They are the only two manufacturers of Talalay latex in the western world.
