I am looking to sell a used wheelchair that I purchased three years ago and have never touched. I did purchase a new backrest for it, which is a J series, and the value of the backrest is $600 (Brand spanking new!) The weight limit is 250lbs. I did not end up using it. It will require a cushion as I do not have one for it. I am quadriplegic and it is better used for somebody with more mobility than myself.
