In an experiment with young male subjects, comfort ratings made after 30 minutes’ sitting permitted discrimination between chairs that were substantially alike except for the bake of the back. Successive ratings made by the same subjects showed no order effects. But ratings made after 5 minutes’ sitting did not permit the same discrimination, and wore distorted by an order effect.
