Doesn't fit every chair
I have a vintage library chair, and it took some "MacGyver-ing" to get the lumbar cushion to 1. stay put and 2. sit in the correct position on my back to provide pain relief and support. It's still not perfect, and I still find myself contorting to odd positions in the chair, but overall I would recommend this product to others. I think my chair is just unusual and not the standard for office chairs.<br /><br />I haven't taken it in the car yet, but I have a 10+ hour drive in a couple weeks and think it will really help.
