Abstract: A housing component of a handheld electronic device, the housing component comprising a cellular material which has a density of from 0.02 to 0.6 g/cc and a Young's modulus of from 32 to 5500 Mpa, the cellular material being three-dimensionally shaped to form a substantially resilient body. There is also disclosed a method of manufacturing a housing component of a handheld electronic device, the method comprising the steps of: a. providing a cellular material; and b. three-dimensionally shaping the cellular material to form a substantially resilient body in the form of a housing component of a handheld electronic device.
