I put this back support in my car and it has made a huge difference in my comfort while driving long distances. Seriously, this helps with back support. It's light weight, I honestly didn't expect it have so much support, but it support my back very well. It adds the perfect amount of lower back support in the area where my car seats fail to support my spine. This product seems durable and well made.
I put another back suppoet in my chair. It fits my entire back and thats a good thing because i'm tall and worry about will out of shape,but it’s very sturdy. It's very comfortable and fits my office chair just perfect. It has 2PCS adjustable stripes on the back so you can tighten it or loosen it to your like.
It just might be the only product I've gone out of my way to recommend to other people. You will bot be disappoint with this purchase! :)
