A body support structure includes a structural lattice structure having a first stiffness, and a compressive lattice structure supported by the structural lattice structure and having a second stiffness less than the first stiffness. A skin lattice structure is supported by the compressive lattice structure, wherein the skin lattice structure is resistant to shear deformation in response to a normal force and is expandable in a direction transverse to the normal force.

A seat assembly includes a base and a support platform spaced above the base. The support platform includes a pad having a hinge portion defining a flex region, wherein the pad is pivotable about the flex region. A link has a lower portion coupled to the base and an upper portion coupled to the pad, wherein the upper portion is pivotable with the pad about the flex region.

Presented is a seating apparatus that is enabled to allow a doctor or a surgeon to achieve an appropriate sitting posture during surgery. The seating apparatus includes a seat mount, a strut, a back-rest, a pedal, a seat and a support base. The seat is connected to the seat mount through a fastening means such that the seat is suspended over the seat mount leaving a gap between the seat and the seat mount. The pedal is operatively coupled to a lower end of the strut and the pedal is configured to adjust height of the seat in a hands-free manner. The seating apparatus is modular and it provides an option to user to easily disassemble various components of seating apparatus for easy portability of the seating apparatus.

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

A themed stool that includes a seat, a mainframe component supporting the seat, an inner shaft disposed within the mainframe component, a lower shaft that receives the inner shaft, and a removable base to the lower shaft. The themed stool also includes a mounting bracket assembly that removably attached a three dimensional ornamental figure, a silhouette of a themed figure, or a decorative graphic to the mainframe component of the stool. The mounting bracket assembly can also be removably attached to any stool. The mounting bracket assembly includes a mounting bracket removably attached to one of the three dimensional ornamental figure and the silhouette of a themed figure and at least one attachment bracket that removably attaches the mounting bracket assembly to the shaft of any stool.

A chair assembly includes a back support arrangement including a back support arrangement, a seat support arrangement and a four-bar arrangement that includes a rearward end and a forward end that is adjustable between a raised and lowered positions, and an arm rest assembly adapted to support the arm of a seated user thereon and supported on the forward end of the four-bar arrangement, wherein the rearward end of the four-bar arrangement is pivotably supported from an arm support structure for pivotable movement about a substantially vertical pivot axis such that the forward end of the four-bar arrangement is moveable between a first position and second position located laterally outward from the first position, and wherein the substantially vertical pivot axis is located forwardly of a rearmost edge of an upwardly-facing surface of the seat support arrangement.

A chair control assembly includes a base structure having first and second pivot points spaced from one another, a seat support structure coupled to the first pivot point, a back support structure coupled to the second pivot point and adapted to move between first and second positions, wherein the base structure does not move as the back support structure moves between the first and second positions, and a control link pivotably coupled to the seat support structure for rotation about a third pivot point and pivotably coupled to the back support structure for rotation about a fourth pivot point, wherein the third pivot point is rearward of the fourth pivot point when the back support structure is in the upright position, and the third pivot point moves forward relative to the fourth pivot point as the back support structure moves from the upright to reclined positions.

The present disclosure provides a support device including a body interface layer resting against a user's body, a core adjacent the body interface layer with a plurality of independently acting micro coils surrounded by an enclosure layer, a stabilizing layer more rigid than the enclosure layer and the body interface layer, and an outer layer adjacent the stabilizing layer and which rests against an external surface such as a seat back when the device is in use. The body interface layer includes a curvilinear or parabolic profile with its inflection point toward a central region of the device and tapering toward lateral ends thereof. The body interface layer is thickest toward its intermediate portion which aligns with a central row of the spiral biasing devices, the body interface layer thinner outer intermediate regions aligning with outer spiral biasing device rows, providing for a consistently distributed pressure against the body.

This invention relates to a posture support (1) comprising a wedge-shaped body (3,51,131) constructed from a resiliently deformable material and means to releasably secure the wedge-shaped body to a backpack (151). The invention further relates to a backpack (151) in combination with the detachable posture support (1). The posture support (1) according to the invention may be quickly attached or detached from a backpack (151). In this way, when the posture support (1) is mounted on the backpack (151), the posture support (1) can alleviate the pressure on the spine and intervertebral discs caused by carrying the heavy backpack (1). When the posture support (1) if taken off the backpack (151), the posture support (1) may be used as a sitting posture support to alleviate the pressure on the spine caused by sitting on a flat surface. The posture support (1) is relatively inexpensive and can be produced at a fraction of the cost of many other posture supports.

A seat cushion for improvement of sitting posture and relief from back and leg pain has a seat portion tapering down from a back end toward a narrow front or forward end. The front end is provided with a vertical projection in the nature of a pommel. The pommel or post is sufficiently large to prevent a user from comfortably crossing his or her legs.
