Molded foam spring seat

A molded foam spring seat for attachment to a stackable chair support frame for support of a seated user, comprising:

• a seat cushion having an upper surface and a bottom surface, said bottom surface having a recess positioned therein, said seat cushion including a front side, a back side and first and second sides, said seat cushion front side having a seat cushion overlap extended past a lateral plane of said bottom surface, said seat cushion overlap disposed to extend proximal from a first and a second front corner of said seat cushion;
• a support frame defining an opening therein, said bottom surface of said seat cushion supported by an upper surface of said support frame, said support frame including a front member and a front portion of each of a first and second side of said support frame, said seat cushion overlap extends over said front member and said front portion of each of said first and second sides of said support frame;
• a drop-in frame insertable within said opening in said support frame, said drop-in frame including a front wall and a rear wall having a first and a second side wall attached between said front and rear walls, said drop-in frame defining a central opening therein, said front and rear walls having fastening means thereon;
• and
• a plurality of compression springs spanning said central opening of said drop-in frame, each compression spring detachably extended between said fastening means positioned on said front and rear walls of said drop-in frame, each compression spring being in partial compression proximate said recess in said bottom surface of said seat cushion;
• whereby each compression spring is compressed downward within said recess when the user is seated on said seat cushion, and each compression spring rebounds to partial compression when the user is not seated on said seat cushion.

A spring seat for support of a seated user comprising:

• a seat cushion having an upper surface and a bottom surface, said bottom surface having a recess positioned therein, said seat cushion including a front side bounded by a first and a second front rounded corner, said seat cushion having a cushion overlap extended along said front side and below a lateral plane of said bottom surface, said cushion overlap is extended proximal to said first and second front rounded corners of said seat cushion;
• a support frame defining an opening therein, said seat cushion supported by an upper surface of said support frame, said cushion overlap is extended to overlap said seat frame along said seat cushion front side and proximal to said first and second front rounded corners of said seat cushion;
• a drop-in frame insertable within said opening in said support frame, said drop-in frame including a front wall and a rear wall, each front and rear wall having a first and a second side wall attached thereto, each respective first and second side wall aligned to define a central opening within said drop-in frame, each of said front wall and rear wall having a plurality of connectors positioned in aligned orientation thereon;
• and
• a plurality of compression springs spanning said central opening of said drop-in frame, each compression spring detachably extended between said aligned connectors positioned on each of said front wall and rear wall of said drop-in frame, each compression spring being in partial compression proximate said recess in said bottom surface of said seat cushion;
• whereby each compression spring is compressed downward within said recess when the user is seated on said seat cushion, and each compression spring rebounds to partial compression when the user is not seated on said seat cushion.
