A seat arrangement includes a backrest frame and a base frame with the backrest frame connectable, adjacent the lower extent of each of opposite sides thereof, to respective mounting that facilitate pivotable mounting of the backrest frame to the base frame. Each mounting includes a respective load dispersing member and the backrest frame is connected to the mounting by fasteners inserted laterally of the frame, through the frame and the load dispersing member of the mounting. The fasteners draw each load dispersing member into a respective recess defined by the backrest frame, with each recess having a form complementary to the load dispersing member to define respective base surfaces through which the fasteners extend, and opposing side surfaces. The fasteners, in fastening the backrest frame to the mounting, cause each load dispersing member to be clamped in the respective recess whereby respective adjacent side surfaces of the recess and the load dispersing member are urged into surface to surface contact.
