Seating device having exercise functionality

A seating device comprising:

• a seat;
• a framework comprising a base portion, a backrest portion, and an armrest portion, said framework supporting said seat;
• at least one reduced-friction bracket secured to said backrest portion of said framework and/or at least one reduced-friction bracket secured to said armrest portion of said framework, at least one said reduced-friction bracket comprising:
• a housing having a top wall, a bottom wall, and sidewalls to thereby define an open interior;
• a bottom horizontal roller and a top horizontal roller rotatably connected to said housing sidewalls, said bottom and top horizontal rollers positioned (i) apart from one another and (ii) defining a first gap between said housing sidewalls;
• a first vertical roller, a second vertical roller, and a third vertical roller rotatably connected to said housing bottom wall and said housing top wall, said first, second, and third vertical rollers positioned apart from one another, said first and second vertical rollers defining a second gap between said housing bottom wall and said housing top wall, and said second and third vertical rollers defining a third gap between said housing bottom wall and said housing top wall;
• and
• a fourth vertical roller rotatably connected to said housing bottom wall and said housing top wall, said fourth vertical roller positioned apart from said first, second, and third vertical rollers, said third and fourth vertical rollers defining a fourth gap between said housing bottom wall and said housing top wall;
• wherein said first and second gaps together define a first reduced-friction slot, and said first and third gaps together define a second reduced-friction slot;
• wherein said first and fourth gaps together define a third reduced-friction slot;
• wherein said bottom horizontal and top horizontal rollers are positioned substantially parallel to each other, and said first, second, and third vertical rollers are positioned substantially parallel to each other;
• and
• a plurality of stretchable cords removably secured to said framework;
• wherein each said stretchable cord has a first end connected to said framework and a second free end threaded through a reduced-friction slot in said reduced-friction bracket;
• wherein each said reduced-friction slot has no more than one stretchable cord threaded therethrough.

A seating device, comprising:

• a seat;
• a framework comprising a base portion, a backrest portion, and an armrest portion, said framework supporting said seat;
• at least one reduced-friction bracket secured to said backrest portion of said framework and/or at least one reduced-friction bracket secured to said armrest portion of said framework, at least one said reduced-friction bracket comprising:
• a housing having a top wall, a bottom wall, and sidewalls to thereby define an open interior;
• a bottom horizontal roller and a top horizontal roller rotatably connected to said housing sidewalls, said bottom and top horizontal rollers positioned (i) apart from one another and (ii) defining a first gap between said housing sidewalls;
• and
• a first vertical roller, a second vertical roller, and a third vertical roller rotatably connected to said housing bottom wall and said housing top wall, said first, second, and third vertical rollers positioned apart from one another, said first and second vertical rollers defining a second gap between said housing bottom wall and said housing top wall, and said second and third vertical rollers defining a third gap between said housing bottom wall and said housing top wall;
• wherein said bottom horizontal roller and said top horizontal roller define a first plane, and said first, second, and third vertical rollers define a second plane that is distinct from said first plane, and wherein said first and second planes are substantially parallel;
• wherein said first and second gaps together define a first reduced-friction slot, and said first and third gaps together define a second reduced-friction slot;
• and
• a plurality of stretchable cords removably secured to said framework;
• wherein each said stretchable cord has a first end connected to said framework and a second free end threaded through a reduced-friction slot in said reduced-friction bracket;
• wherein each said reduced-friction slot has no more than one stretchable cord threaded therethrough.
