Recommendations for Portable Stadium Seats?

<p>I wanted to get portable stadium seats to use on the bleachers at Memorial Stadium and Haas Pavilion. I don’t want to rent the CalSeats, which are $55/football season. According to the Memorial Stadium GameDay Visitors Guide (<a href=“http://www.calbears.com/ViewArticle.dbml?DB_OEM_ID=30100&ATCLID=209612296#prohibit”>http://www.calbears.com/ViewArticle.dbml?DB_OEM_ID=30100&ATCLID=209612296#prohibit&lt;/a&gt;; see A-Z guide under “Seatbacks.”), seatbacks brought in by fans must measure 14" or less in width.</p>

<p>According to CalSeats, their seats are approximately 17" wide. Can anyone recommend a portable seat that is comfortable, provides back support, and has been successfully used in Memorial Stadium and/or Haas Pavilion (they were allowed in the stadium)? I’ve seen several seats on Amazon that look comfortable but are greater than 14" wide.</p>
