Abstract (en)
[origin: CA3057933A1] An ergonomic chair includes a support body having a seat support portion and a back support portion. A forward sloping seat track is positioned on the seat support portion. A first seat portion engages the seat track on the seat support portion for forward and rearward movement along the seat track between a forward position and a rearward position. A second seat portion is provided having an upwardly extending back rest. The second seat portion is pivotally connected to the first seat portion. Movement of the first seat portion forward along the seat track toward the forward position draws the second seat portion forward with forward movement of the second seat portion causing movement of the back rest downwardly. This allows for subtle movement forward and backward movement that energizes major leg muscles.
