1. A passenger seat assembly comprising:
a seat base; and
a backrest connected to the seat base and comprising a frame, wherein the frame comprises a tubular frame component having a variable inner diameter such that a first portion of the tubular frame component comprises a first wall thickness and a second portion of the tubular frame component comprises a second wall thickness that is different from the first wall thickness, and wherein the tubular frame component further comprises a transition portion between the first portion and the second portion, the transition portion having a changing wall thickness increasing or decreasing in thickness between the first portion and the second portion;
wherein the first portion of the tubular frame component is a first bent portion bending the frame at a nonzero angle within a first plane defined by the backrest,
wherein the backrest defines a second plane, and wherein the second portion of the tubular frame component is a second bent portion bending the frame at a nonzero angle within a second plane defined by the backrest,
wherein the tubular frame component further comprises a third bent portion bending the frame at a nonzero angle within a third plane, wherein the third plane is different than the first plane and the second plane, and
wherein the second bent portion further comprises a third wall thickness that is different from the thickness of the first bent portion, the transition portion, and the first portion.
