We prepared 10 types of expanded beads and 12 types of expanded bead cushions in order to estimate tactile impression using sensory evaluation on an SD scale. In this paper, we focused on the properties of expanded beads. Of the various types of multiple classification analyses, multi-regression analysis and quantification theory I were applied to the results of the sensory evaluation. Prediction formulae were made and it was found that the bead diameter was important for all sensory words in this research. The expanded beads with a diameter less than 1.5 mm were related closely to tactile impression. It was found that the diameter of 1.0-1.5 mm was a threshold value of the tactile impression. The sensory evaluation results for each sensory word were explained by the score of the item/category. The diameter and evenness of the expanded beads were important bead properties. The relationship between the sensory evaluation results and the mechanical properties of the expanded beads was examined.
