The wheelchair bag has: - a zipper pocket - 2 outer pockets - 1 inside pocket which can be divided to make 2 - a key tab - Velcro straps This bag will not fit every chair. An 11" distance between the arm of the chair down to the top of the wheel is required to accommodate this bag.. If you are considering purchasing the pattern, please measure the wheelchair first. The wheelchair with smaller wheels is the best. I have recently made another wheelchair bag, similar to this one. The difference is an elasticized pocket across the front, a 3" gusset, instead of 2", and a tab for holding a water/juice cup. The mini tutorial is included with this one, showing the steps. Please contact me if you have any questions/concerns! SIZING / FINISHED MEASUREMENTS 10" X 10"
