Convenient
It is convenient. Small, easy to inflate. The valve system is great. The key is that you can let our air slowly while leaning against it to find the perfect fill, and then it really conforms to your back extremely well and surprisingly comfortable, you can forget it's just a travel/inflatable pillow. It's worth it if you have a flat hard back seat you want to make more comfortable. Be wary that you really need to have the right spot to strap it in place or it will move. And I don't find it good for orthopaedic position improvement on an already decent chair, more for making a hard chair more comfortable.
