Abstract: A molded foam spring seat includes a seat cushion having a bottom surface supported by a support frame having an opening therein. A drop-in frame is insertable within the opening, with the drop-in frame including a pair of opposed walls having fastening means thereon. A plurality of compression springs are each detachably extended between the fastening means on the drop-in frame. Each compression spring is in partial compression until compressed downward by a user seated on the seat cushion. Each compression spring resiliently rebounds to partial compression when the seat cushion is not compressed. The seat cushion includes sides tapered inwardly toward a seat cushion upper surface to reduce bulging of each side outwards with repetitive use of the seat cushion, and to minimize wear on the seat cushion sides when other seat cushions and support frames are positioned adjacent, or are stacked on the seat cushion.

Abstract: A chair including a seat assembly having an improved seat spring system to provide a flexible spring backrest frame. A pair of ends of spaced apart backrest frame members are arranged in registry with respective ends of seat support frame members, with each end positioned in spaced apart alignment across a gap from the respective end of each frame member. An elongated shaped flexible spring element spans each gap, with each spring element having opposed ends being extended a distance along each frame member from the gap. Each opposed end is restrained by a first and a second elongated U-shaped holder receptor paired and separately attachable to each opposed end of the spring element. Each holder receptor includes an opening end being faced towards and in alignment with the second holder opening end. The spring element is positioned between each opening end in side-by-side orientation beside the frame members, providing controlled angular range of motion of the backrest frame when moved by a chair occupant.
Abstract: A lid for a container having an opening is configured to close the opening. The lid includes a base adapted to fit the container opening and an actuator configured to engage the base. The base includes a deformable portion which, when deformed, will pass the contents of the container therethrough. The actuator is moveable between a closing position and an opening position and is operable to deform the deformable portion such that, when the actuator is in its closing position, the contents of the container are blocked from passing through the deformable portion and, when the actuator is in its opening position, the contents of the container will pass through the deformable portion.
