Investigation of other gender-based interactions showed that the use of armrests did not affect female pressure distributions, and that reclined trunk–thigh angle only seemed to reduce female pressure distributions to a limited extent, with 1201 showing no significant additional reduction beyond that provided at 1101. Males did experience statistically significant reduction in pressure distributions through the use of armrests though the difference was slight. Males also experienced a linear reduction in pressure factor values due to increased (reclined) backrest angle. Male pressure distributions therefore appeared to be affected by posture to a greater degree than female distributions.
