Disclosed herein is a cylindrical rocker mechanism including a top assembly having a first cavity, a middle assembly including at least one middle lug aligned with the first cavity to facilitate insertion of a first pin therethrough thereby coupling the top assembly with the middle assembly, a second cavity aligned perpendicularly to the at least one middle lug, a bottom assembly having a horizontal plate, and at least one bottom lug aligned with the second cavity to facilitate insertion of a second pin therethrough thereby coupling the top assembly with the middle assembly, wherein the top, and middle assemblies move and roll in perpendicular directions thereby facilitating a friction dependent, substantially slip-less, omnidirectional, rolling and a tilting motion of the top assembly in response to a force applied by a subject to top assembly.

A seating apparatus cushioned for providing comfortable seating of a body for living room, office and other seating environments. The seating apparatus includes a frame for a seat, a back component, arms and legs and includes one or more supports fixed with respect to the frame and extending from the seating apparatus to provide stationary anchors for use by the body in exercising and for ingress and egress from the seating apparatus.

An ergonomic chair has a back support member and means for arranging and supporting legs of the user in an asymmetric configuration, with a first leg extending in front of a body of the user and a second leg aligned with or extending behind the body of the user. An angle between the first and second legs in a side view can be at least 30 degrees. The means for arranging and supporting legs can comprise one or more fixed structures that support the first leg in a first orientation, or one or more dynamic structures that can be positioned by the user to support the first leg in a first orientation. In some embodiments, with the legs of the user in the asymmetric configuration, a centerline of the user is offset from a centerline of the back support member with respect to a lateral direction.

An inversion chair and the method of treatment are provided to assist a user in the treatment and prevention of migraine headaches by increasing and altering the blood flow within the head. The inversion chair includes a frame having a first and a second side connected to each other by a fixed backrest. The sides of the frame have L-shaped configurations comprising upstanding side and base sections that are connected by a curved member. A rotatable seat is positioned between the sides of the frame. The chair is adapted to transition between a standard sitting position to an inverted position. The chair comprises an upper user support bar and a lower leg support bar for maintaining a user within the chair during inverted use. The support bar is removable and used to either secure the lap of the individual when inverted, or support the chair when in an upright state.

Novel sit-stand seating devices, more particularly, to sit-stand seats or stools that can tilt forward to provide balanced support for seated to near-standing postures and methods of their use are disclosed. The sit-stand devices are useful, inter alia, to provide stabilized worker positioning to carry out a task for a range of sitting through standing postures in an environment associated with a task for a worker in need thereof.

Systems and methods for exerting forces on a body, including a support structure defining a space and a plurality of surface contacting units that are configured to exert force upon the body, such that the weight is distributed away from the primary weight bearing regions to non-weight bearing regions of the body, or vice versa, without exerting significant shear or frictional forces on surfaces of the body. The systems and methods may be used to exert forces to cause fluid shift in different compartments of the body. Applications include treatment of various disease conditions including pressure ulcers, heart failure, high blood pressure, preeclampsia, osteoporosis, injuries of spine and to slow microgravity-induced bone and muscle loss. The systems and methods may be used to simulate gravity, weightlessness or buoyancy, in rehabilitation medicine. The system may include a chair, bed, a wearable suit or an exoskeleton.

An ergonomic chair comprising a seat, a lower leg support, a chest support and a hip support. The seat is configured to support the posterior thigh and/or buttocks of a seated user, the seat being configured to urge the hip of the seated user in a forward direction. The lower leg support is configured to support the anterior side of the lower legs of the seated user. The chest support is configured to support the chest of the seated user in a forward leaning position of the seated user. The hip support is configured to support the anterior hip of a seated user as the seat urges the seated user’s hip forwardly towards the hip support.

A mobile body unweighted sit and stand chair assembly prevents repetitive stress from sitting, standing, and lifting objects for long periods. The assembly provides a vertically, rotatably, and pivotally adjustable seat, a restrictive support padding that rotates from a support bracket to selectively support the spine or the pelvis, and a frame for structural integrity, mobility, and steering. The seat supports the buttocks and the ischium region of the pelvis, tilting forward up to 35 degrees to abut the pelvis against the support padding. This forward position maintains the spine in a straight posture and forces open posterior intervertebral disc space. The seat is supported by an adjustable rod that supports the weight of user while sitting, walking, kneeling, or lifting. A frame includes wheels that enable mobility and a brake. A first bracket enables feet to steer for hands-free maneuverability. A second bracket provides balance during kneeling and lifting.

A standing chair apparatus for improving stretching and comfort for a user, for use with a standing desk, the apparatus includes a movable base. The standing chair further includes a calf stretching plane on the movable base. The standing chair further includes a tower portion, extending from the movable base, the tower portioning including multiple stretch points.

A yoga exercise apparatus that is operable to reduce pressure on the crown of the head of the user as well as the wrist and hands during certain yoga body positions. The present invention includes a first member, second member and third member that are identically constructed with the first member having a larger diameter than the equal diameter of the second member and third member. The first member, second member and third member are annular in shape each having a central portion and an integrally formed outer ring. The central portion has an upper surface that is recessed within the outer ring. The bottom of the central portion includes a plurality of walls forming pockets that will function to releasably secure the present invention to a floor. The second member and third member are placed on opposing sides of the first member during use of the present invention.
