WebILD Test of Polyurethane Cushions and Pillows The firmness of a polyurethane foam cushion and pillows is measured by performing a test called indentation load deflection, or ILD. To the manufacturer and final user, it is one of the more important quality tests related to the firmness of the end product. WebIndentation Force Deflection (IFD) - also known as Indentation Load Deflection (ILD), is the measure of a foam material's resistance to a compression force. This measure is used to determine the "firmness" or "softness" of the foam. IFD is the amount of force it takes to compress a sample to a specified amount of deflection. impact call activity https://cvorider.net
