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.

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 seat assembly includes a frame, a seating base layer, a compression limiter layer, a load distribution layer, and an adjustment module. The seating base layer is arranged on the frame. The compression limiter layer is arranged adjacent to the seating base layer and comprises a wave portion forming a knee support. The load distribution layer is connected to the compression limiter layer. The adjustment module is movable between a rear position and a forward position and is configured to move the wave portion between a retracted position and an extended position. The wave portion has one of more first wave elements formed as springs and one or more second wave elements formed as springs. The first wave elements are offset from the second wave elements in a radial direction.

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.
