A passenger seat which includes a seat bottom chassis assembled from a plurality of leg modules attached to fixed, spaced-apart attachment points on a supporting surface, and a plurality of beam elements for being carried by the leg modules. A plurality of clamp joints are positioned on a first side of the leg modules in a first laterally-offset relation thereto in a first spaced-apart relation to the attachment points of the supporting surface and for receiving the plurality of beam elements for defining a ladder frame assembly having a first specified width and seat spacing. The plurality of clamp joints are removable from the first side of the leg modules can positioned on a second, opposite side of the leg modules in a second laterally-offset relation for defining a ladder frame assembly having a second specified width and seat spacing while the plurality of leg modules maintain the same position relative to each other and thus to the fixed, spaced apart attachment points whereby the location of the seats may be altered while using the same beam elements.
