A model has been developed to calculate the heat release rate of a mattress by a gas burner at the centre of the upper surface. The model describes flame spread of an ignition front radially outwards from a cylindrical flame at the centre. The heat release rate is calculated using the data obtained from cone calorimeter tests at an irradiance of 35 kW/m2 and assuming that each increment on the surface goes through the same burning history as in the cone calorimeter test. The preheating heat flux outside the burning area is assumed to be a constant of 25 kW/m2 up to a distance depending on the diameter and heat release of the flame. The model successfully predicts the heat release rate of the mattresses tested in the furniture calorimeter in CBUF-programme. Especially, the model seems to be able to predict whether the fire will grow or go out on its own after the ignition source is removed.
