11. 11 . The seat assembly of claim 1 , comprising a seat frame, wherein the cushion is connected to the seat frame; and the trim cover, the trim wire, and the coupling are not directly connected to the seat frame.
12. 12 . The seat assembly of claim 11 , wherein the trim cover, the trim wire, and the coupling are indirectly connected to the seat frame via the cushion.
13. 13 . The seat assembly of claim 1 , wherein the trim wire is rigid.
14. 14 . The seat assembly of claim 1 , wherein the coupling includes a metal hog ring.
15. 15 . The seat assembly of claim 1 , wherein the trim wire is snap fit with the cushion.
16. 16 . The seat assembly of claim 1 , wherein the cushion is not molded with the trim wire or the coupling.
17. 17 . The seat assembly of claim 1 , wherein the cushion is a seat base cushion or a seat back cushion.
18. 18 . A method of assembling the seat assembly of claim 2 , the method comprising: disposing the trim cover on the first surface of the cushion; inserting a portion of the trim cover into the through aperture; inserting the trim wire into the recess such that the trim wire is detachably connected to the cushion; and connecting the portion of the trim cover to the trim wire via the coupling.
19. 19 . The method of claim 18 , further comprising molding the cushion separate from the trim wire and the coupling.
20. 20 . The method of claim 18 , wherein inserting the trim wire into the recess includes snap fitting the trim wire with the cushion.
