A spring wall for securement between associated end members for forming an associated gas spring assembly includes a first wall portion that extends axially along a longitudinal axis and circumferentially thereabout. The first wall portion is formed from an unreinforced elastomeric material, and the first wall portion has a first nominal stiffness value. A second wall portion extends along the longitudinal axis and circumferentially thereabout. The second wall portion is disposed in longitudinal relation to the first wall portion and has a second nominal stiffness value that is different from the first nominal stiffness value of the first wall portion such that a non-constant stiffness profile is established along a longitudinal length of the spring wall. A gas spring and a gas spring and reservoir assembly utilizing such a spring wall as well as a method of manufacturing a gas spring are also included.
