This is perfect for me. I have had 3 standard lower back supports, and 1 slim-profile support. I liked the slim one best because otherwise the standard ones push me too far forward in the seat. My car is small so I am already as close to the steering wheel and pedals as I want to be. This lumbar roll supports just the part of my back where I need it, without pushing my hips and legs forward. I have to adjust it when I get in the car, mainly depending on where my back needs support at the time: sometimes higher, sometimes lower. I see this as an advantage, that I can adjust it where it needs to go. I have not had the problem that some report with the elastic slipping through the fastener. Maybe someday the elastic will stretch a bit, or pull out. I've had it for a month and am very happy.
