发明名称 Stackable chair
摘要 A stackable chair is provided which is configured to alter the forward shift of the center of gravity of a stack of the chairs such that a larger number of such chairs can be stacked in a stable stack as compared to a stack of prior art chairs. The stackable chair includes a seat member, a seat back extending from the seat member, a plurality of legs secured to the seat member and a seat pan secured to the bottom of the seat member. The seat member defines a wedge shape and the seat pan is disposed at angle with respect to the seat member. The seat member and the seat pan cooperate to alter the forward shift of the center of gravity to an arcuate path when the chairs are placed in a stack. Further, the seat pan is configured to protect the seat cushion upon which it rests against indentations.
