6. The method according to claim 4 , further comprising:

inserting the rod into the plurality of loop portions concurrently; and

stretching the seat suspension layer from the first side frame member towards the second side frame member by means of the rod.

7. The method according to claim 4 , further comprising:

inserting the rod into one of the plurality of loop portions;

stretching the seat suspension layer from the first side frame member towards the second side frame member by means of the rod;

fastening one of the plurality of retainers on the second side of the seat suspension layer onto one of the second plurality of support members on the second side frame member.

8. The method according to claim 7 , further comprising:

inserting the rod into a subsequent loop portion of the plurality of loop portions; and

fastening a subsequent retainer of the plurality of retainers on the second side of the seat suspension layer onto a subsequent support member of the second plurality of support members on the second side frame member.

9. The method according to claim 2 ,

wherein the loop member is sewn along the second side of the seat suspension layer.

10. The method according to claim 1 ,

wherein the retainer comprises a pair of opposing edges connected by a connecting edge,

wherein the retainer is fastened to the support member such that the pair of opposing edges extends in the direction substantially perpendicular to the plane defined by the first and second side frame members.

11. The method according to claim 1 ,

wherein the retainers are made of plastic, metal, composite, or a material having sufficient strength for the retainers to hold the seat suspension layer.

12. The method according to claim 1 ,

wherein the support member is arranged to protrude substantially perpendicularly from the respective plane defined by the first and second side frame members.

13. The method according to claim 1 ,

wherein the seat frame is a seat back frame or a seat pan frame.

14. The method according to claim 1 , wherein the seat suspension layer comprises a seat suspension fabric.

15. A passenger seat, comprising
