A lumbar support system (100) for an aircraft seat includes a deformable lumbar support basket (103) having a proximate end (104) and a distal end (106). The system includes a shape memory alloy tension cable (112) in communication with the proximate end (104) of the deformable lumbar support basket (103), and the distal end (106) of the deformable lumbar support basket (103). The shape memory alloy tension cable (112) has a changeable tension length with an electric current through the cable (112). The system (100) also includes a controller (102) operatively connected with the shape memory alloy tension cable (112). The controller (102) transmits the electric current through the shape memory alloy tension cable (112) based on the user actuation. The electric current causes the shape memory alloy tension cable (112) to deform the lumbar support basket (103) by tension force applied to the proximate end (104) of the deformable lumbar support basket (103) and the distal end (106) of the deformable lumbar support basket (103).
