A Multifactorial Approach To Specify Comfortable Rail Seats

BACKGROUND: A robust rail seat comfort assessment can inform the GB rail industry when procuring new seats and identify areas for comfort improvement in the refurbishment of existing seats, improving the customer experience.OBJECTIVE: To take a multifactorial approach to measuring comfort and to create a robust seat comfort assessment method for the GB rail industry.METHODS: Seat comfort assessment scores were developed by identifying seat dimensions (e.g. Seat height, seat width, seat depth), seat pad thickness and hardness requirements, seat accessories and seat attractiveness components. Scores for each seat feature were verified by conducting a fitting trial and asking 7 participants to rank dimensions through a range of adjustment. The combined scoring of features was verified by asking 14 participants to rank seats in three configurations (minimum comfort). The seat comfort dimensions scores were then validated by ranking seven existing rail seats using the assessment method and comparing the ranks with subjective comfort ranks of 12 participants.RESULTS: The validation testing resulted in a moderate positive correlation, indicating an alignment between the seat comfort assessment method and subjective comfort scores.CONCLUSIONS: A multifactorial seat comfort assessment has been shown to be a good indicator of passenger seat comfort.
