Seating assemblies and methods are disclosed. A seating assembly (100) can comprise a seat, a back support (114), and a frame component (110). The frame component can extend from a bottom portion (118), positioned near an underside of the seat, to a top portion (120), configured to maintain the back support at a position above the seat. The back support can laterally extend from a left edge portion (1670) to a right edge portion (1672) and can include a spring member (122) at or near each of the left and right edge portions. The spring member can include at least one undulation or arc (1674) providing integrated rated compression adaptation to a user. The seating assembly can further comprise a tilt mechanism (408), engaged with the frame component, including one or more leaf springs (424) and a spring contact assembly. The spring contact assembly (426) can be positioned on a top side of the one or more leaf springs.

The seating assembly of claim 1, wherein the spring member is configured such that, when the at least one or more undulations or arcs is compressed, a distance between the rearward surface of the back support and the top portion of the frame component is reduced. 3. The seating assembly of claim 2, wherein a maximum distance reduction, between the rearward surface of the back support and the top portion of the frame component, is at least 2 inches. 4. The seating assembly of claim 1, further comprising a tilt mechanism, engaged with the frame component, including one or more leaf springs and a spring contact assembly, the spring contact assembly positioned on a top side of the one or more leaf springs. 5. The seating assembly of claim 4, wherein the one or more leaf springs include a stacked arrangement of two or more leafs or a composite leaf. 6. The seating assembly of claim 4, wherein the tilt mechanism further includes a slide linkage, engaged with a front end portion of the seat, configured to confine upward movement of the front end portion during backward translation of the seat. 7. The seating assembly of claim 4, further comprising an adjuster mechanism, coupled to the spring contact assembly, configured to adjust a force of the one or more leaf springs acting on the frame component by changing a location of the spring contact assembly along a length of the one or more leaf springs. 8. The seating assembly of claim 7, wherein the adjuster mechanism includes a lever arm engageable with one or more ratchet teeth when the location of the spring contact assembly, along the length of the one or more leaf springs, is selected. 9. The seating assembly of claim 8, wherein the adjuster mechanism includes at least three guide rollers engaged with a pivoting end, having an arc configuration, of the lever arm. 10. The seating assembly of claim 1, wherein the seat and the back support each include a plurality of flexes voids, the flex voids associated with the seat having foci positioned at seat locations configured to receive the user's ischial tuberosities bones. 11. The seating assembly of claim 1, wherein the seat includes at least one seat valley, positioned along or near a centerline of the seat, configured to allow a left edge portion and a right edge portion of the seat to deflect in one or both of a downward direction or a lateral direction. 12. The seating assembly of claim 1, further comprising a first tier and a second tier, spaced from the first tier, of foot support platforms or rings. 13. The seating assembly of claim 12, wherein at least one of the first tier or the second tier includes an opening to a support surface positioned underneath a front edge of the seat. 14. The seating assembly of claim 1, further comprising an arm rest rotatable in and out of position. 15. The seating assembly of claim 1, further comprising a foot support assembly, deployable from a first position to a second position, including a foot support platform and at least one foot support arm configured to support the foot support platform about a curvilinear translation movement between the first and second positions. 16. A method comprising: receiving, at a tilt mechanism, a force adjustment acting on a frame component;maintaining a portion of a back support in contact with a user at and between a first orientation and a second orientation, maintaining including: compressing a spring member having at least one or more undulations or arcs at or near each of left and right edge portions of the back support as a result of space between members joined at an angle of the one or more undulations or arcs at the left and right edge portions, respectively, andchanging a distance between a rearward surface of the back support and a top portion of the frame component supporting the spring member as a result of the compression of each of the one or more undulations or arcs of the spring member at or near the left and right edge portions of the back support; andtranslating a seat about the tilt mechanism as the user moves between the first orientation and the second orientation. 17. The method of claim 16, wherein receiving the force adjustment includes changing a location of a spring contact assembly along a top side of one or more leaf springs. 18. The method of claim 17, wherein changing the location of the spring contact assembly on the top side of the one or more leaf springs includes changing an orientation of the seat and back support. 19. The method of claim 17, wherein changing the location of the spring contact assembly along the top side of the one or more leaf springs includes receiving a rotating force, at a lever arm engaged with the spring contact assembly, about a virtual pivot point generated by three guide rollers engaged with an arced end of the lever arm. 20. The method of claim 16, further comprising rotating a cam-shaped arm rest from a first supporting position to a second supporting position, including changing an effective supporting position height, relative to the seat, via the rotation. 21. The method of claim 16, further comprising receiving, at the frame component, a second seat or a second back support to replace a removed first seat or a removed first back support. 22. The method of claim 16, wherein maintaining a portion of the back support in contact with the user includes changing the distance between the rearward surface of the back support and the top portion of the frame component about at least 4 inches from an unstressed state. 23. The method of claim 16, wherein translating the seat about the tilt mechanism includes creating a pubic arch in a front edge of the seat during a forward-leaning orientation or creating a flattened front seat lip during a backward-leaning orientation. 24. The method of claim 16, further comprising deploying a foot support assembly synchronized with, and activated by, movement of one or both of the seat or the back support.
