Stature: subject stood erect heels together, looked straight ahead, arms hung loose at the sides.
Popliteal height: subject sat erect on the bench, feet height was adjusted to bring thighs horizontal and parallel, lower legs vertical – vertical height from foot surface to top surface of bench.
Knee height: subject same as (3) – vertical height from foot surface to superior aspect of right patella.
Thigh clearance height: subject same as (3) – vertical height from top surface of bench to the junction of thigh and abdomen.
Buttock-knee length: subject same as (3) – horizontal distance from block held against rearmost part of buttocks to edge of right patella.Dimensions Measured
Buttock breadth – seated: as for (3) – horizontal width across the greatest lateral protrusion on each side of the buttocks.
Sitting height – normal: subject sat normally relaxed on the bench hands in lap, looking straight ahead – vertical height from top surface of bench to top middle part of the head.

1. For U.S. data, only 5th and 95%tiles were available. Thus assumed that these points were 3.29 standard deviations from the means of a normal distribution.
2. Differences in clothing - U.S. subjects stripped to the waist, emptied their pockets and wore short gowns.
-Limited application to real-world working postures.
