The seat of claim 18 wherein said armrests further comprise:at least one biased sliding latch having a laterally extending protrusion on one side of said latch; and a pair of detents for engagement with said laterally extending protrusion for securing said armrests in a first and a second position. 20. The seat of claim 19 which further comprises a generally flat-bottomed seat saver portion under said seat member.21. The seat of claim 20 which further comprises a cup holder in said seat saver portion.22. The seat of claim 19 wherein said movable member further comprises an aperture toward a top of said movable component.23. The seat of claim 20 wherein said sliding latch further comprises:a laterally extending cam follower; and a cam surface having a geometry to effect axial movement of said sliding latch and said laterally extending protrusion. 24. The seat of claim 23 wherein said cam surface generates upward axial movement of said sliding latch when moving said armrest from a lowered position into a raised position thereby permitting pivotal rotational movement of laterally extending protrusion from a first detent position to a second detent position.25. The seat of claim 24 wherein pivoting rotational movement is prohibited when said armrests are in a lowered position.26. The seat of claim 1 wherein said means for selectively positioning said seat member from said essentially L-shaped first position to said second essentially collapsed position comprises a pivoting latch which prohibits rotational movement of said seat member toward said back member.27. A collapsible car seat which comprises:a seat member; a back member pivotally connected to said seat member, said back member further comprising: a fixed component; and a telescoping movable component overlapping said fixed component, said telescoping movable component further comprising a fixed upper headrest area with a pair of forward extending wings and wherein movement of said components relative to each other provides contiguous support for an occupant's back; and means on said car seat for selectively positioning and retaining said car seat in an essentially L-shaped first position or a second essentially collapsed position wherein a top of said seat member is adjacent to a front of said back member; means for selectively positioning and retaining said movable component relative to said fixed component. 28. The seat of claim 27, wherein said back member and said seat member share a common axis that allows said back member and said seat member to pivot toward each other.29. The seat of claim 28 wherein said seat member and back member are shaped such that said seat member and said back member nest when folded together.30. The seat of claim 29 wherein said movable component is attached in front of said fixed component.31. The seat of claim 30 wherein an inner contour of said movable component mates with an outer contour of said fixed component.32.
