  • Subjective/objective comfort surveys

    Hello All,

    I am trying to quantify comfort for a comparison study on mattresses. The
    test subject lays supine for a given amount of time and asked to rate their
    amount of comfort. Besides the "smiley face" survey widely used in US
    hospitals for pain levels (and associating a numerical value to each face)
    and having the subject place a dash on a 10 cm line with one end being
    extremely uncomfortable and the other end being extremely comfortable and
    measuring the distance in cm to get a numerical value, are there any other
    reliable methods/ surveys anyone has used successfully in the past?

    I also have a version of a survey that identifies specific areas of the
    body for evaluation (neck, shoulders, upper back, etc.) Right now I'm
    investigating a combination of the three mentioned above and was wondering
    if anyone can offer any guidance.

    Any suggestions are most appreciated and I will post a summary of responses
    if there is interest.

    Thank you in advance,
    Rebecca
