A passenger seat assembly comprising a plurality of passenger seats, wherein the passenger seat assembly comprises:
- a plurality of spreaders, each spreader comprising an upper portion and a lower portion separated by a transitional region;
- a plurality of seat backs, each seat back comprising a central panel and a pair of extensions coupled to a lower end of the central panel, wherein the pair of extensions are pivotally coupled to the upper portions of two of the plurality of spreaders;
- a base structure comprising a forward base frame tube and an aft base frame tube, wherein the forward base frame tube and the aft base frame tube pass through a pair of apertures in the lower portion of each spreader;
- and
- at least two leg assemblies, each leg assembly comprising a forward leg portion, wherein the forward base frame tube and the aft base frame tube pass through a pair of apertures in the forward leg portion,
- wherein an upper end of the forward leg portion of each leg assembly has a downward pitch in a forward direction between the aft base frame tube and the forward base frame tube such that the forward base frame tube is located at a lower height than the aft base frame tube.
