Chair and method for constructing a chair

A chair constructed from a sheet of generally rectangular, rigid material, comprising:

• said sheet of material having a first end portion adapted to form a front support structure, a second end portion adapted to form a rear support structure and a generally upright back support structure, and an intermediate portion adapted to form a seat;
• said first end portion being generally vertically arranged;
• said intermediate portion being generally horizontally arranged and bifurcated into a plurality of longitudinal strips extending from said first end portion, a first portion of said longitudinal strips extending from said first end portion at a first preselected height and a second portion of said longitudinal strips extending from said first end portion at a second preselected height differing from said first preselected height;
• and
• said second end portion being bifurcated into a plurality of longitudinal strips coextensive with said intermediate portion longitudinal strips, said first portion of said longitudinal strips being bent downwardly from said intermediate portion thereby forming said rear support structure, said second portion of said plurality of longitudinal strips being bent upwardly from said intermediate portion thereby forming said back support structure.

A method for constructing a chair from a sheet of generally rectangular, rigid material, comprising the steps of:

• making a plurality of longitudinal cuts extending from a second end portion of said sheet of material toward a first end portion of said sheet of material to form a plurality longitudinal strips being separated at their second end portion and connected at their first end portion;
• bending said sheet of material adjacent said first end portion transverse with said longitudinal axis to form an angle of intersection in the range of 135 to 45 degrees between said first end portion and an intermediate portion of said sheet of material, whereby said first end portion forms a front support structure and said intermediate portion forms a seat;
• selecting a first and second portion of said longitudinal strips;
• bending said first portion of said longitudinal strips in a direction toward said first end portion to form an angle of intersection in the range of 135 to 45 degrees between said second portion of longitudinal strips and said intermediate portion of said sheet of material, whereby said first portion of longitudinal strips forms a rear support structure;
• and
• bending said second portion of said longitudinal strips in a direction away from said first end portion to form an angle of intersection in the range of 90 to 135 degrees between said second portion of longitudinal strips and said intermediate portion of said sheet of material, whereby said second portion of longitudinal strips form a back support structure.
