  9. Chapter 7 Supplement (7.3.5) discusses the use of one wire in securing the vertical seat cushion to the specimen frame. The survey of labs above shows that multiple wires are being used not only on the vertical cushion, but the horizontal cushion as well. Full-scale testing of both restrained and unrestrained leather seats is being considered at the Tech Center. Use of Wires in Restraining Test Cushions:
