Large sofa cushions (Hackney Cross WR13)

We have just replaced our two large sofa cushions from a three seater sofa. I am not sure if anyone could make use of the foam before we take them to the HRC e.g. use the outer parts to make new cushions, use the foam as a pet bed? We are in Cradley. Collection, any time as can leave it out under our canopy. There is no fire label. Thanks, Nichola
