A task chair, including a backrest assembly and a seat assembly pivotally coupled both to one another and to side portions of a fixed yoke member for synchronized movement, in which the seat of the seat assembly moves upwardly and forwardly concurrently with recline of the backrest of the backrest assembly. The chair further includes a tension assembly including an elongate tension member, such as a leaf spring, secured at one end thereof to the yoke member, and a contact member, such as a contact roller, adjustably mounted to the seat assembly. The contact member engages the tension member such that the tension member resists recline of the backrest assembly and concurrent movement of the seat assembly from their initial positions, and also provides a restoring force which tends to move the backrest to its initial upright position and the seat to its initial rearward and lowered position. The contact member is adjustable with respect to the tension member in order to vary the effective moment arm acting upon the tension member, thereby varying the pre-load of the tension member and the resistance provided by the tension member.

A support pillow that comprises a pillow body having a medial region and two curved arms that extend from the medial region to define a generally open well. A back rest extends vertically upward from the medial region. This configuration permits an infant to be placed in the open well, with the curved arms of the pillow body supporting the infant from tipping side to side and the back rest supporting the infant's back. Conveniently, the back rest may be incorporated into a slipcover that is placed over the pillow body.

In some embodiments a fold flat easel for the display of a device folds open from a flat piece of plastic into an upright standing position. Multiple position notches in the rear of a base accept a kickstand and a foot and varies the resting angle of a backrest. The backrest together with an arresting lip on the base secures the device on the easel. The backrest is attached to the kickstand and the base with flexible and durable living hinges. The entire stand, including hinges, can be easily and cost effectively fabricated from a single piece of plastic. Other embodiments are described and claimed.

A seating assembly having a seat and a seat back. A frame assembly is disposed in each of the seat and the seat back. A carrier assembly is operably coupled with the seat and the seat back. The carrier assembly includes a plurality of elongate support tabs proximate the seat. A plurality of apertures and at least one groove are proximate the seat back. A cushion extends over the seat and the seat back.

A passenger seat for a vehicle includes a seat back; and a seat bottom, which may be mounted to a fixed backshell. The seat bottom is selectively configurable such that at least a portion of one side thereof is higher than at least a portion of the opposite side thereof, relative to a floor of said vehicle, so as to support a passenger who is seated on said seat bottom in a rotated position wherein one of said passenger's hips is higher than the other hip relative to said floor.

A chair has a backrest and a pair of armrests. A pair of support struts for supporting the backrest is connected to a shaft of a base under a seat. The armrest is supported by an arm post. An operating lever is mounted on the upper front end of the arm post. When the backrest is tilted, it is held at a desired angle by pressing up the operating lever.

An exercise device includes: a frame member; a pair of foot rests connected to the frame member; a seat that can be moved along the frame member; and, a back rest that can be pivoted with respect to the seat. By moving the seat along the frame member a user can move between an upright seated position and an extended planar position. By pivoting the back rest with respect to the seat a user can move between an upright seated position and a laid out position.
