A rollator is disclosed, including first and second upright members, each including handle portions, wheels, hinges disposed between the wheels and the handle portions, channels disposed along the upright members between the hinges and the wheels, and lateral hinges orthogonal to the hinges. First and second foldable support members having wheels are attached to the hinges. At least one lateral support member is disposed between and attached to the lateral hinges, and includes an intermediate hinge. Brake systems include brake lines communicating between brake controls and brakes. In a reversible storage configuration, the foldable support members are rotated to be at least partially disposed in the channels, and the lateral hinges and intermediate hinge rotate to collapse the lateral support member, bringing the upright members with the folded foldable support members adjacent to one another.

1. A rollator, comprising: a first upright member including a first handle portion at an upper end of the first upright member, a first wheel at a lower end of the first upright member, and a first hinge disposed between the first wheel and the first handle portion;a second upright member including a second handle portion at an upper end of the second upright member, a second wheel at a lower end of the second upright member, and a second hinge disposed between the second wheel and the second handle portion;a first foldable support member including an upper end of the first foldable support member attached to the first hinge, and a lower end of the first foldable support member including a third wheel;a second foldable support member including an upper end of the second foldable support member attached to the second hinge, and a lower end of the second foldable support member including a fourth wheel; andat least one lateral support member disposed between and attached to the first upright member and the second upright member;wherein the first foldable support member and the second foldable support member are arranged and disposed to rotate at the first hinge and the second hinge between a storage configuration and an engaged configuration, such that in the engaged configuration the first foldable support member and the second foldable support member are reversibly locked at a predetermined angle to the first upright member and the second upright member, andwherein the at least one lateral support member is arranged and disposed to transition between the storage configuration in which the at least one lateral support member is in a collapsed arrangement with the first upright member adjacent to the second upright member, and the engaged configuration in which the at least one lateral support member is in an extended arrangement with the first upright member distal from the second upright member across a length of the at least one lateral support member, the at least one lateral support member being reversibly locked in the extended arrangement. 2. The rollator of claim 1, wherein the first upright member includes a first channel disposed along the first upright member between the first hinge and the first wheel, the second upright member includes a channel disposed along the second upright member between the second hinge and the first wheel and the second wheel, the first foldable support member includes a conformation which fits at least partially within the first channel, the second foldable member includes a conformation which fits at least partially within the second channel, and in the storage configuration, the first foldable member is at least partially disposed within the first channel, and the second foldable member is at least partially disposed within the second channel. 3. The rollator of claim 1, wherein the at least one lateral support member includes at least one hinge, the at least one hinge reversibly transitions from a folded state in the collapsed arrangement and an unfolded state in the extended arrangement, and the at least one hinge is reversibly lockable in the extended arrangement. 4. The rollator of claim 1, further including at least one brake system having at least one brake control, at least one brake associated with at least one of the wheels, and at least one brake line communicating between the at least one brake control and the at least one brake. 5. The rollator of claim 4, wherein the at least one brake system is reversibly lockable in a fully engaged configuration. 6. The rollator of claim 4, wherein the at least one brake system is reversibly lockable in a partially engaged configuration. 7. The rollator of claim 4, wherein at least about 50% of the at least one brake line is disposed within the first upright member, the first foldable support member, the second upright member, the second foldable support member, or combinations thereof. 8. The rollator of claim 1, wherein the first wheel, the second wheel, the third wheel, and the fourth wheel are arranged and disposed such that in the storage configuration, the first wheel and the fourth wheel are at least partially disposed between the second wheel and the third wheel, or the second wheel and the third wheel are at least partially disposed between the first wheel and the fourth wheel. 9. The rollator of claim 1, wherein the at least one lateral support member includes a first lateral support member and a second lateral support member. 10. The rollator of claim 1, further including a removable seat having a seat bottom and a seat back. 11. The rollator of claim 10, wherein the removable seat reversibly attaches to the first upright member and the second upright member above the at least one lateral support member. 12. The rollator of claim 11, wherein the removable seat further attaches to the first foldable support member and the second foldable support member. 13. The rollator of claim 10, wherein the removable seat is arranged and disposed to rotate between a first position in which the seat bottom is reversibly locked about parallel to the first upright member and the second upright member, and a second position in which the seat bottom is reversibly locked about parallel to a plane defined by the first wheel, the second wheel, the third wheel, and the fourth wheel. 14. The rollator of claim 10, wherein the seat back is arranged and disposed to rotate between an open position in which the seat back is reversibly locked about perpendicular to the seat bottom, and a closed position in which the seat back is reversibly locked about parallel to and adjacent to the seat bottom. 15. The rollator of claim 10, wherein the seat back attaches to the seat bottom on a rail along the seat bottom, and the removable seat is arranged and disposed such that the seat back is slideable between a first end of the seat bottom and a second end of the seat bottom. 16. The rollator of claim 10, further including removable support arms positioned at a height suitable for stabilizing and aiding a transition of an individual between a seated and a standing position. 17. The rollator of claim 10, wherein the removable seat is arranged and disposed to compress laterally when the rollator transitions from the engaged configuration to the storage configuration, and expand laterally when the rollator transitions from the storage configuration to the engaged configuration. 18. The rollator of claim 1, wherein the rollator in the storage configuration includes a height of less than about 40 inches, a width of less than about 9 inches, and a depth of less than about 15 inches. 19. The rollator of claim 1, wherein a height of the rollator is adjustable by at least about 3 inches while in the engaged configuration. 20.
