A connection assembly for a backrest, of an office or conference chair, includes a backrest structural element, a transverse support element, a transverse bearing by means of which the backrest structural element is rotatably coupled to the transverse support element in a direction perpendicular to a transverse direction, and a connection portion connecting the transverse support element to the backrest structural element, arranged and formed so that the backrest structural element is resiliently movable relative to the transverse support element.

A chair is provided having at least one leg with an upper end on which a seat component is supported and a backrest interconnected to and projecting from the seat component. The backrest comprises a lower backrest section, an upper backrest section, and a backrest hinge interconnecting the upper backrest section to an upper end of the lower backrest section. The lower backrest section is interconnected to and extends from a rear portion of the seat component and the backrest hinge is configured to permit the upper backrest section to be located in an upright position in which the upper backrest section projects above the lower backrest section and is configured to permit the upper backrest section to be pivoted to a forward position in which the upper backrest section extends laterally over and spaced above the seat component.

The present invention surrounds a seating apparatus having an arm-rest assembly configured to traverse behind a seat-back, and arm-rests which extend forward of the seat back. Embodiments discussed herein include an inflatable chamber for providing positive buoyancy and structure. Certain embodiments of the present invention are configured primarily for use in a body of water, while other embodiments are configured for use in water or upon a surface.

A seat back support assembly comprises a vehicle engaging member and a seat back receiving member. The vehicle engaging member is configured to be secured to a vehicle body. The vehicle engaging member includes a supporting section. The seat back receiving member includes (i) a base that is adjustably coupled to the supporting section, and (ii) a receiver that is coupled to the base, the receiver being configured to receive the seat back. The base is alternately positioned in a first vertical position and a second vertical position relative to the supporting section. When the base is in the first vertical position, the seat back is at a first height relative to the vehicle seat. Alternatively, when the base is in the second vertical position, the seat back is at a second height relative to the vehicle seat that is different than the first height.

Additionally, when the base is in the second vertical position, the seat back is at a second height relative to the vehicle seat that is different than the first height.

This disclosure relates to a cushion and more particularly to a pillow providing cervical alignment by way of a cervical spine support structure that is positioned along a major axis of the pillow, and that can be rotated around the major axis. The pillow utilizes one or more of the following features: 1) a dimensionally correct platform for the proper sleep posture of a majority of body types on a wide array of mattress types; 2) A non-crush zone integrated cervical support roll which can be adjusted for extended durations of supportive comfort. (The rollin and of itselfis unique compared to the standard of care because of its foam densities and its semi-hollowed out section); and 3) A sleep posture platform with a side sleeping position and a back-sleeping position. The pillow standardizes care by placement of the support roll inside a dimensionally correct platform using different materials.

A folding stool comprises a seat portion, a backrest and a hinge device connecting the seat portion and the backrest. The hinge device comprises a first hinge and a second hinge rotatably connected. Two first hinges are respectively fixed to the backrest and the seat portion, the first hinge comprises two ear portions, the second hinge comprises four ear portions, and the four ear portions of the second hinge are respectively connected to four ear portions of the two first hinges by means of two rotary shafts. A position limiting board is fixed on the back surface of the second hinge, and the position limiting board comprises two oppositely provided position limiting surfaces.
