摘要：
This is a cover piece for a seat member of a bleacher seat unit. One embodiment is a single resilient polymeric piece adapted to be flexed and placed over a seat member which is provided with a front extension portion to effectively extend the front surface of the seat member. Another embodiment is a cover piece made up of two or more pieces including a top cover portion and at least one second cover piece sufficiently resilient to hold the top cover portion against the seat member.
