A lumbar support cushion is placed behind your lower back when you are sitting down in your car seat or in an office chair. It’s great for supporting the lordotic curve of your spinal column. Many of the chairs, which we use, do not conform to the shape of our body. Therefore, we tend to slouch and become unaware of our correct posture. This is not an optimal position for you to stay for extended periods. When you slouch, you place more stress on your muscles, ligaments and vertebral discs in your lower spine that can lead to problems such as disc herniation. With a lumbar pillow, you can support the spine in your lower back to make it more stable and save you in the end.
