Description	Currently, great emphasis is placed on improving and optimizing of sitting comfort (car seats, chairs, sofas, hospital mattresses...). The comfort is also related to safety, quality, air permeability and ergonomics, which all depend on the mechanical properties of the used material. Polyurethane foams (PU) are most widely used for comfort layers. PU together with upholstery fabrics creates complete comfort layers. With the rapid oil disappearance and its price growth there are efforts to find new solutions which allow replacing PU foam with suitable materials. Preferably recyclable materials are wanted for that purpose. An experimental quasi-static indenting of a load body to a PU sample is the starting point for simulations. Obtained experimental data are used as a comparison for the model simulated in FEM. An evaluation criterion is essentially the contact pressure of the tested sample.
