- Research into foam durability by measuring flex fatigue, or the loss of foam firmness after flexing the foam a predetermined number of cycles, shows that as polymer density increases, firmness loss is usually lessened. Less firmness loss means that, for example, seat cushions and mattresses can much of their original “feel” over extended periods of normal use. Higher density foams also tend to retain their ability to provide support. Other factors used to gauge foam durability can also improve a · pfa.org
