The base includes a top surface and a bottom surface. The seat cushion also includes a generally wedge-shaped main cushion, and a generally rectangular-shaped back cushion, wherein the main and back cushions engage the base. The seat cushion is moveable between a deployed configuration and a rolled configuration.

An inflatable portable lumbar pillow is an apparatus that includes a plurality of inflatable cushions connected serially via a plurality of intermediate webs, a first end strap opposite to a second end strap that retains a strap fastener, and a strap fastener that utilizes a first interlocking portion and a second interlocking portion to wrap around a wearer's waist. The first end strap is connected adjacent to the plurality of inflatable cushions. The second end strap is connected adjacent to the plurality of inflatable cushions, opposite the first end strap. The first interlocking portion connects onto the first end strap, offset from the plurality of inflatable cushions, and the second interlocking portion connects onto the second end strap, offset from the plurality of inflatable cushions, thereby securing the first end strap to the second end strap.

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.

The present disclosure relates to configurable stacking chairs having a standard seat base frame design to which different interchangeable seat backs can be quickly and easily attached. The seat base frames and the interchangeable seat backs may include corresponding quick-connect features that allow selective attachment therebetween. The interchangeable seat backs may be attached to a standard seat base frame via a magnetic connection. Each interchangeable seat back can have a different unique design allowing for a quick change of appearance by exchanging one interchangeable seat back design for another. The interchangeable seat backs and the standard seat base frames can be stored separately and take up less space than completely assembled or fixed back chairs.

A connecting assembly for a sofa includes a first connecting piece fixing on a first component of the sofa, a second connecting piece fixing on a second component of the sofa, and a third connecting piece. The first connecting piece includes a first inserting portion. The second connecting piece includes a second inserting portion. A first end of the third connecting piece is inserting into and connecting with the first inserting portion. A second end of the third connecting piece is inserting into and connecting with the second inserting portion. When the third connecting piece is gradually inserting into the first inserting portion and the second inserting portion, contact pressures between at least portions of the third connecting piece, the first inserting portion and the second inserting portion gradually increases to make the third connecting piece clamping to the first inserting portion and the second inserting portion.

A method for generating a rebounding motion between a person and a surface includes the steps of providing a rebounding device, positioning the rear member against the surface and the front member adjacent to an upper body of the person and the surface, and applying pressure to the rebounding device through the upper body. The rebounding device includes front and rear members having front and rear widths spanning right front and rear side edges and left front and rear side edges and first and second spring mechanisms positioned between the front and rear members. The first and second spring mechanisms are positioned between the right front side edge of the front member and the right rear side edge of the rear member and between the left front side edge of the front member and the left rear side edge of the rear member, respectively.

A backrest having features that support proper sitting posture of a user to improve back health and posture may be utilized. The backrest may include a front wall with wings extending to the left and right and diagonally forward to reduce Kyphosis of a user when sitting against the backrest. A combination of the front wall and wings may causing the user's (i) back ribs to be raised and gently tilted forward and (ii) thoracic spine region to be gently thrusted forward. By thrusting the thoracic spine region and raising and tilting the back ribs, a user's abdominal cavity may be expanded, and thereby reinforcing the ideal positioning of the cervical spine so that the user's head naturally positions on axis and does not “dump” forward.

Knock down sectional couches and related wedge sections and methods. In accordance with an example, a knock down wedge section for use with a sectional couch includes a wedge-shaped seat and a pair of back sections. The wedge-shaped seat having a front portion, a back portion including a first back portion and a second back portion, and lateral portions. Each of the first back portion and the second back portion carries a pair of male knock down bracket portions. Each back section carries a pair of female knock down bracket portions. Each female knock down bracket portion is adapted to receive and form a coupling with a corresponding male knock down bracket portion.
