A buttocks elevating auxiliary seat cushioning system includes a chair having a seat and a backrest that is attached to and extends upwardly from the seat. The seat has an upper surface angled downwardly toward the backrest. A cushion assembly is positioned on the upper surface of the seat and abuts the backrest. The cushioning assembly has a top side, a front side, a rear side, a first lateral side, a second lateral side and a bottom side. The top side is angled upwardly from the front side to the rear side when the bottom side is abutted against the seat and the rear side is abutted against the backrest. The cushion assembly is resiliently compressible.

A strut member is connected to the center of a top plate portion which supports a seat portion and the center of a base portion so that the strut member rockably supports the top plate portion. A pair of rocking mechanisms formed by motors and link mechanisms connected to the output shafts of the motors and the top plate portion, and configured to be vertically displaced in accordance with a rotation of the motors is arranged in a front area or a rear area compared to the strut member in the base portion. The axial direction of the motor of one of the rocking mechanisms is aligned with a left oblique direction from the center of the supporting surface, and the axial direction of the motor of the other of the rocking mechanisms is aligned with a right oblique direction from the center of the supporting surface.

A cushion for a piece of furniture or a pillow includes a cushion core and an exterior cover at least partially surrounding the cushion core. The cushion core comprises a cushion wrap surrounding a filler, which may be foam or fiber or down or any known filler. The cushion wrap is at least partially made of fabric having a raised surface pattern to increase friction between the cushion core and the exterior cover for holding the cushion core in a desired orientation inside the exterior cover.

A removable cushion for a chair having an outer surface and an inner foam, as well as at least one magnetic member. The inner foam and the outer surface are formed from the same polymer, with the outer surface forming an integral skin over the inner foam. The outer surface defines an upper surface and a lower surface. The lower surface is structurally configured to be positioned in an abutting relationship with a seating surface of a chair. The at least one magnetic member is embedded within one of the outer surface and the inner foam, the at least one magnetic member positioned closer to the lower surface than the upper surface of the outer surface. A chair having the cushion, and a mold is likewise disclosed, as is a method of manufacturing the cushion.

A foldable cushion includes a cushion mechanism and a connecting mechanism. The cushion mechanism includes a seat unit and a back unit. The seat unit and the back unit are juxtaposed and movable relative to each other along a transverse folding line. The connecting mechanism includes a first endless cord and a second endless cord. The first endless cord and the second endless cord respectively extend through the transverse folding line and are flexibly arranged on the seat unit and the back unit. When the seat unit and the back unit are moved relative to the transverse folding line, the first endless cord and the second endless cord are stretched, so that the seat unit and the back unit are positioned at an expanded state by the elastic force of the first endless cord and the second endless cord.

A portable seat and back cushion for posture correction. The device includes a seat member with an inflatable bladder or a foam insert and a back member that is foldably connected to the seat member. A customizable support member is disposed within the back member. The customizable support member may include either an inflatable bladder with a plurality of individually adjustable bubbles arranged in a vertical row or a semi-rigid insert with a plurality of selectively positionable vertebral support nodules.

A seat pad includes a supporting device, a shaping positioning portion, and an elastic member. The supporting device has a receiving space. The shaping positioning portion is at the outer periphery of the receiving space. The elastic member is arranged in the receiving space of the supporting device. The elastic member includes a contact surface in the shaping positioning portion, and the contact surface can be seated by a buttock of a user to hold the buttock of the user.

A portable support, pain or pressure relief device comprising a plurality of pillows where a first pillow comprises an opening. A second pillow is disposed in the opening forming an aperture and is selectively adjustable in the opening to adjust a shape and size of the aperture.

A removable cushion for a chair having an outer surface and an inner foam, as well as at least one magnetic member. The inner foam and the outer surface are formed from the same polymer, with the outer surface forming an integral skin over the inner foam. The outer surface defines an upper surface and a lower surface. The lower surface is structurally configured to be positioned in an abutting relationship with a seating surface of a chair. The at least one magnetic member is embedded within one of the outer surface and the inner foam, the at least one magnetic member positioned closer to the lower surface than the upper surface of the outer surface. A chair having the cushion, and a mold is likewise disclosed, as is a method of manufacturing the cushion.

There is provided an air cushion in which air chambers rise when a user is seated.

An air cushion including an outer welded portion along an outer peripheral portion of a flat bag-shaped object includes: a first air chamber as a seating portion; a second air chamber as a side support portion; and a third air chamber as a side support portion, wherein the air chambers communicate with each other through passage portions and an inner welded portion is provided that has a U character.
