An accessible bench assembly requires specific dimensional clearances and structural support to meet accessibility standards. The seating surface sits between 17 and 19 inches above the finished floor, with a depth ranging from 20 to 24 inches. The bench backrest is positioned 18 to 20 inches above the seat and maintains a maximum gap of 2 inches from the seat. Structural supports must be engineered to withstand a 250-pound load applied in any direction.
