The 14" Seat Sack Standard comes in multiple colors and lets you keep school supplies close at hand. Just slide it on over the back of your seat and you can get to your pencils, tape, glue, scissors and more without having to reach into your backpack. You can also set it up on the desk in front of you for easier access. This chair storage pocket fits in a way that lets you stack the chairs while the unit is attached. It's made from a poly laminated fabric that's treated with flame retardant for safety and durability. Cleaning the chair pocket is as easy as tossing the unit in with your laundry to make it look like new.
