A support surface including a cutout on a bottom surface of the support surface. The cutout, which can include a set of cutouts, provides a controlled structural collapse of the support surface by varying a stiffness in a cross-section. That is, the area in which the cutouts are positioned collapses more easily than the surrounding area of the support structure, thus making the area with the cutouts perceived as being softer. The cutouts can reduce the peak pressures on the portion of the user's body (for example, the user's ischial tuberosities) that is positioned over the cutouts. The support surface can also include a low-friction interface extending across a top surface of the support surface.
An example interchangeable decorative feature described herein includes an interchangeable panel provided on a housing of a task chair. The panel provides aesthetic functionality by allowing a user to readily customize, modify, personalize, or otherwise alter the design, theme, or aesthetic of the example task chair. The panel is interchangeable and includes a snap-fit joint coupling the panel to a surface of the chair. The snap-fit joint includes a hybrid annular-cantilever snap-fit. The snap-fit joint includes a feature configured to aid in readily engaging and disengaging the panel to and from the back support.

An example gas lift cylinder removal device described herein includes a collar assembly having a guide pin, a set screw, and a lead screw. The example cylinder removal device is disposed on a gas lift cylinder and provided proximate to and below a seat plate assembly of an example task chair. Operation of the gas lift cylinder removal tool from a first position to a second position provides a mechanical advantage to impart an upward force on a bushing of the seat plate assembly, thereby displacing the cylinder from the seat plate assembly. An example task chair having the gas lift cylinder removal tool is described herein comprising a support surface, a seat plate assembly, and a base assembly, the seat plate assembly including a bushing, an upper plate and a lower plate.

A seating configuration is described. The seating configuration includes a first support surface configured to support the Ischial Tuberosities of a user. The first support surface includes a feature to urge a user into an optimal position on the seat. The seating configuration includes a second support surface positioned adjacent a pelvic-sacral-lumbar region of the user. The seating configuration includes a third support surface positioned adjacent a thoracic-cervical region of the user. The first, second, and third support surfaces, respectively, together can be configured to create a natural alignment of a spinal column of the user.
The disclosure provides a chair or seat assembly comprising a seat, a back support, and a support arm coupling the back support to the seat. The support arm comprises an illumination and control assembly. The illumination and control assembly comprises an illuminator, and a controller coupled to the illuminator. The illumination and control assembly further comprises an accelerometer, and the controller is coupled to the accelerometer.

A support surface including a cutout on a bottom surface of the support surface. The cutout, which can include a plurality of cutouts, provides a controlled structural collapse of the support surface by varying a stiffness in a cross-section. That is, the area in which the cutouts are positioned collapses more easily than the surrounding area of the support structure, thus making the area with the cutouts perceived as being softer. The cutouts can reduce the peak pressures on the portion of the user's body (for example, the user's ischial tuberosities) that is positioned over the cutouts. The support surface can also include a low-friction interface extending across a top surface of the support surface.
A base for a chair is described. The example base for the chair includes a central support coupled to a seat of the chair, a first pair of legs extending radially from the central support, and a second pair of legs extending radially from the central support. The first pair of legs extend in a direction opposite the second pair of legs. A first angle between the first pair of legs is larger than a second angle between the second pair of legs. Respective legs of each of the first pair of legs and the second pair of legs are rotationally fixed relative to the seat of the chair.
A chair is described herein. The chair includes a first back support coupled to a base of the chair using one or more first support arms. The chair also includes a second back support coupled to the base of the chair using one or more second support arms. The first and second back supports are independently rotatable about a common axis.
