Lumbar Support: The Key to Pain-Free Sitting
Lumbar support maintains the natural curve of your lower spine. Without it, your back flattens and discs compress.
Your lumbar spine has a natural inward curve (lordosis) that acts as a shock absorber. When you sit without lumbar support, this curve flattens and pressure on your spinal discs increases by up to 40%. A lumbar cushion or built-in chair adjustment restores the curve, distributes pressure across your sit bones, and keeps your upper body aligned. Look for adjustable-height lumbar support that fits the curve of your specific lower back.
