Latex is a heavy and elastic type of foam.
As stuffing material Latex ensures rather heavy and solid cushions, which at the same time are soft and "alive".
As a component in mixtures with e.g. feathers from sea birds or siliconized fibres, Latex ensures an extremely good seating comfort.
B6 is only using Talalay latex, which gives a very homogeneous cushion of very high quality.
