Abstract
A seat of an apparatus, in one example, comprises a front subportion and a rear subportion that is adjustable in height and/or angle relative to the front subportion. A backrest of the apparatus, in one example, is adjustable in shape. Based on a manipulation of adjustments, a subportion of the seat and the backrest are adjustable between: a first height and/or angle of the rear subportion of the seat and a first shape of the backrest; and a second height and/or angle of the rear subportion of the seat and a second shape of the backrest.

An apparatus, comprising:
- a) a seat that comprises a front subportion and a rear subportion wherein the rear subportion is supported by an one or more adjustable supports;
- b) a means for adjusting a rear subportion;
- c) a backrest;
- d) a lumbar contact substrate;
- and
- e) a means for adjusting position of the lumbar contact substrate;
- wherein, manipulation of the rear subportion adjustment means changes the position of the rear subportion of the seat from a first height and/or angle of the rear subportion of the seat to a second height and/or angle of the rear subportion of the seat;
- and wherein, manipulation of the backrest shape adjustment means changes the shape of the backrest from a first shape of the backrest to a second shape of the backrest, and manipulation of the lumbar contact substrate adjustment means changes the position of the lumbar contact substrate.
An apparatus, comprising:
- a seat that comprises a front subportion and a rear subportion that is supported by an one or more adjustable supports;
- a lumbar contact substrate;
- a backrest;
- an adjustment mechanism in communication with the rear seat subportion and the lumbar contact substrate;
- and
- wherein, manipulation of the adjustment mechanism changes the position of the rear seat subportion from a first position to a second position and the lumbar contact substrate changes shape from a first shape to a second shape.
A method, comprising the steps of:
- adjusting a lumbar region of a backrest between a first shape and a second shape based on manipulation of a manual adjustment means;
- and
- adjusting a rear subportion of a seat between a first height and/or angle and a second height and/or angle relative to a front subportion of the seat based on manipulation of a manual adjustment means.
