This is a seat for drivers. It's easy to install, so it's recommended for people who: * Drive a lot for work * Have back pain * Get tired easily while driving * Work at a desk Simply attach it to your usual chair or car seat. It distributes your weight and reduces the burden on your lower back by 20kg. The three-dimensionally moving backrest gently wraps around both sides of your lower back. It firmly supports your back in any sitting posture. It doesn't compress the spinal cord, so it's gentle on people with back pain. The color is a familiar navy. There are no particularly noticeable scratches, but there are some minor ones. There are no instructions, so please be aware of that. \#duorest \#duorest \#seat support \#cushion
