Comfortable for your lower back! The Drive & Business Yok-Rest. It fits your lower back and provides moderate cushioning. It can be used not only to protect the lower back of drivers, but also as a companion for long trips, for adjusting the distance for female drivers, for individualizing your lower back support in the office, and even as a simple pillow when you're tired. I stored it after hardly using it after purchase. There may be some scratches and stains from storage, so please consider this if you don't mind. Please refrain from purchasing if you are sensitive to such things.
