Hi Elizabeth,
Thank you so much for taking the time to write your feedback. We are happy that you love the Parent Cup Holders, but we also hear the concern. Thank you for notifying us. Just in case you are looking we do offer a Catch All add on. It will hold a water bottle or phone or keys etc. It is made of Spandex laminated SBR foam. So, it is more durable.
