ABSTRACT:
A stacking interface device (10) for altering the stacked disposition of a chair (12) to facilitate the stable stacking of such chair on other chairs. The stacking interface device (10) includes an interface body (14) for being secured beneath the seat bottom (16) of a chair (12), the interface body (14) having a forward portion (18) and a rearward portion (20). The interface body (14) also defines a lower surface (22) for supporting the chair upon the seat cushion (24) of a second chair (12). The lower surface (22) of the interface body (14) is disposed at an angle relative to the lower surface (26) of the seat bottom (16) of the chair to which the device (10) is attached such that the distance between the lower surface (22) of the interface body (14) and the lower surface (26) of the seat bottom of the chair decreases from the forward portion (18) of the interface body to the rearward portion (20) of the interface body (14).
