A chair has a metal base, a matrix of metal tubes having a common outside and an inside diameter, welded orthogonal to the metal base, extending vertically, and a matrix of posts matching the matrix of metal tubes, the posts bored for a portion of a length of each post, with each post engaged over one of the metal tubes. The chair is characterized in that one row of posts along one edge of the metal base comprises posts of a height greater than other posts, and forms a backrest for the chair, and in that the remaining matrix of posts, of a lesser height than the posts forming the backrest, are of a common height, and form a seat surface for the chair.

The present invention belongs to the technical field of mesh chairs, in particular to a spring-type iron frame mesh chair, wherein it comprises a chair body, and a reinforcement is fixed to the side of the chair body by welding. A mesh body is fixed on the side surface of the reinforcement. Spring bodies are fixed on the inner side of the reinforcement by welding. A connecting ring is connected to one end of the spring bodies different from the reinforcement. An adjusting rod is integrally arranged on the side surface of the chair body. The adjusting rod penetrates the side wall of the chair body. When the mesh chair is in use, the spring bodies can pull the reinforcement by their own elasticity. Pressure is applied to the reinforcement and the spring bodies when the mesh body is under pressure, so that the mesh body becomes flexible and elastic to a certain extent, which improves the user experience. When the adjusting rod is adjusted, the position of the connecting ring is changed simultaneously and the length of the spring bodies varies, then the elasticity of the spring bodies is changed, which makes it easy to adjust the elasticity of the mesh body and improve the user experience.

A seat has a supporting frame being rigid, two seat cushions disposed above the supporting frame, and two supporting members. The supporting frame has a main body and four side bodies fixedly mounted on two front ends and two rear ends of the main body. The supporting members are mounted on bottom surfaces of the seat cushions and are connected to the supporting frame. Each one of the supporting members has multiple supporting elements respectively located at a front half section and a rear half section of a corresponding one of the seat cushions. Each one of the supporting elements has a guiding rod mounted on the supporting frame and a main spring disposed around the guiding rod. The seat provides good support by the supporting frame and the supporting members and provides a cushioning performance by the main spring.

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

A body support structure includes a structural lattice structure having a first stiffness, and a compressive lattice structure supported by the structural lattice structure and having a second stiffness less than the first stiffness. A skin lattice structure is supported by the compressive lattice structure, wherein the skin lattice structure is resistant to shear deformation in response to a normal force and is expandable in a direction transverse to the normal force.

The invention relates to a height-adjustable supple member for lying and/or sitting furniture, including one or more adjustable springs and a rotary part. Each adjustable spring is configured to change in height along a central axis under the effect of a radial stress relative to the central axis. The rotary part includes one or more rails each extending over an angular sector about the central axis, in a plane perpendicular to the central axis, from a first end to a second end more distant from the central axis than the first end. Each rail cooperates, in the radial direction relative to the central axis, with a corresponding adjustable spring among the one or more adjustable. The rotary part is able to rotate, about the central axis, so as to exert, through each rail, said radial stress on the corresponding adjustable spring.

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

A pocket spring mattress for use in a bedding or seating product is disclosed. The mattress comprises a plurality of interconnected coil springs enclosed in continuous covers forming strings of pockets accommodating the coil springs. Adjacent coil springs within each string are spaced apart by an interjacent separation distance, said separation distance exceeding at least 20 percent of the diameter of the largest one of the spiral turns of the adjacent coil springs. Further, the pocket spring mattress further comprises a cushioning pad located above the upper end of each coil spring, wherein the covers provides first compartments enclosing the coil springs, and second compartments enclosing the cushioning pads, said first and second compartments being separated from each other. The cushioning pads each have a length extension in the longitudinal direction of the strings exceeding the diameter of the largest one of the spiral turns of the corresponding coil spring.
