They help keep items in good shape and give additional space that the student's desk is short on. Teachers love seat sacks because they aid in limiting classroom clutter and aid teaching organizational skills.

HOW TO MEASURE FOR POCKET WIDTH:

MEASURING INSTRUCTIONS:
The pockets are custom made to your chairs,
I tell the teachers to take a string, wrap it around the widest point of the top 6” of the chair back, add a couple inches for storage room, measure the string then divide in half, that would be the size to order, Thank You!!!

Seat Sack storage pocket simply slides on the back of a chair to provide instant storage of books, papers, school supplies and more. These Seat Sacks are made from sturdy material, double stitched at stress points. I would recommend air drying. Chairs stack easily without removing Seatsacks
If the material needs to be ordered it will take 7 business days for me to get the material from supplier, and a few more days to make them, again depending on the amount of orders I have before yours.
Notice how they are a bit larger than the chair back, to allow room for supplies in the pocket. I say this because some have been ordering them too small, and wanting to return them, just please measure your chairs first, to assure we do the correct size. I'm sorry, but if they are ordered too small, I can not exchange them free of charge because they are custom made for you. If you have any questions cheapest please contact me, I do not mind!!!! Thank You!!!!

CARE INSTRUCTIONS:
Machine washable on most gentle cycles. I washed mine on the Hand Wash cycle, laid it flat wiping the wrinkles out, let it air dry, and it just needs a quick ironing. I recommend trying only one pocket first to see how it does. Hand-washing or dry cleaning are also options to keep the pockets from shrinking and/or raveling. My local cleaners charges $2.25 each to clean them. I can not replace chair pockets damaged from machine washing.
