The Organizer® is tied around seats’ headrest from one corner to the other with additional center support and fastens to the bottom of seat cushion coils with S hooks which are provided. Can be used on any seat. Available in three sizes; small, medium and large with multiple sized pockets to stow away just about anything to keep the vehicle neat and tidy. The small is perfect for all bucket seats regardless of headrest style. The medium is perfect for all small pick-up bench seats and 2nd row bench seats for most minivans, SUVs and crossovers, while the large is great for full size trucks and full size SUV bench seats. Each size offers multiple size pockets to accommodate small to large items. Keep all your essentials such as writing/drawing instruments, toys, tissues, papers, files, maps, water bottles, etc… organized and where you need it when you need it. If you travel with infants and/or kids you’ll really appreciate having those handy items to entertain and care for them at your fingertips and keep their feet prints off front seats too.
