The benefits of a good lumbar support are immeasurable. A lot of people struggle with back problems, many of which are preventable. When we sit, we have a tendency to slouch forward. This causes bad posture, and is a very hard habit to break over time. Unfortunately, this slouching can cause the lumbar to bend outward, the opposite direction of how it naturally wants to bend. These issues range from moderate to severe, but all can cause chronic back pain.
