A core of springs with monolithic perimeter frame and reinforced and stabilized edges, of the type used for the manufacture of seats for furniture or mattresses, which is comprised of: an arrangement of springs that can be manufactured from independent bag-lined cylindrical springs; and a layer of support material or bottom on which the arrangement of springs is arranged, the dimensions in length and width of said layer of support material being greater than those of the arrangement of springs, thereby generating a surplus of material around the arrangement of springs that supports, which is characterized in that; a monolithic perimeter frame of foamed material made in situ on the surplus material of the support layer, surrounds and reinforces the arrangement of springs, so that said perimeter frame is firmly joined as part of the chemical reaction of its foaming and adhesion process. |

A seating cushion with a pocketed spring assembly includes a plurality of interior strings of springs joined to each other. The interior strings of springs comprises a plurality of interconnected pockets. Each pocket contains at least one coil spring. The pocketed spring assembly forms a central matrix. The pocketed spring assembly further includes at least one perimeter string of springs. Each perimeter string of springs comprises a plurality of interconnected perimeter pockets. Each pocket of the central matrix has a maximum diameter or width of a first dimension and each pocket of the perimeter string of springs has a maximum diameter or width of a second dimension. The first dimension is greater than the second dimension. |

An angle adjusting device is provided, which includes a ratchet, multiple sliders, an expansion and retraction mechanism, and a sliding groove plate. The ratchet is provided with n inner teeth; and m slider groups consisting of the multiple sliders include one base slider group and m−1 deflecting slider groups, where the outer teeth of the deflecting slider groups have an angular deflection about a central shaft of the ratchet with respect to the outer teeth of the base slider group, and the angular deflection is (Z+k/m)360/n degrees, and 1≦k≦m−1, and the expansion and retraction mechanism is capable of simultaneously push the multiple sliders to extend in radial directions. The outer teeth of different sliders can simultaneously abut against or be engaged with the inner teeth at different phases, thus achieving the stable securing and stepless adjusting of the ratchet position. |

The present invention discloses a cushion for providing a user to sit on. The cushion includes a base layer, a seat layer and a supporting portion. The seat layer is configured on the base layer for providing the user to sit on. The supporting portion is configured between the base layer and the seat layer for supporting the user's ischial tuberosity. The seat layer is made with the material of the good covering shape, thus it can release user's upper body, hips and legs. Furthermore, by using the hard supporting portion for supporting the user's ischial tuberosities, the cushion makes the weight of the user's upper body be transmitted uniformly to the seat layer. Therefore, the cushion can prevent the user's hips and legs from some physical pains such as sore, ache, and pain due to long period of partial stress. |

An office, work and leisure chair and retrofit kit for subliminal motions of the seated person. The chair has a cruciform base (1) with rollers (4), a pneumatic spring-action post (2) with an interface plate (5) for a seat panel (21) and seat pad (19), and a backrest (22). The seat panel is mounted with wobble capability on a pneumatic cushion, which has deformable air chambers (18, 35) connected by connecting hoses (27) and lies on an elastically deformable hollow body (14). The hollow body pumps the air chambers when a person sits down and stands up. A pump hose (12) with a one-way valve leads from the hollow body to compensate for leakage losses. Connecting hoses between the air chambers have valves (31; 75; 89) such that the wobbling distance of the seat panel and the damping of the wobbling motion is variable. |

A lift chair includes a lift mechanism that maintains a continuous seating position during forward and elevated movement by supporting the occupant's seat, arms and back. The mobile section of the chair will also lower the occupant to the normal seating height. The gel cushion seating surface is attached at least to the moveable section of the lift chair. The gel cushion seating surface of the chair has a plurality of gel cushion cylinders arranged in a grid that provide a rhythmically changing support area at multiple points on the occupant's buttocks and thighs. This provides a comforting massage which reduces stress on the body associated with prolonged seating. |

The invention relates o a chair having a seat structure formed by a frame member that defines a central opening. A flexible membrane extends across the central opening. A pair of support pads, one disposed on either side of the cross-beam member, is provided and arranged at a level below the central opening of the frame member. The support pads are arranged within the seat structure so as to be rearwardly disposed with respect to the front edge of the frame by a first distance and spaced apart from each other by a second distance, the first and second distances generally corresponding to the positioning of the ischicial tuberosity of a user when the user assumes a seated position engaging the seat structure. |
