Long hours at a desk can lead to back pain, poor posture, and fatigue—especially when your chair lacks proper ergonomic support.

Tips

Adjust the seat height so your feet rest flat on the floor and your knees form a 90-degree angle. Use the height-adjustable armrests to support your forearms without raising your shoulders. For optimal lumbar support, position the backrest so its curve fits the natural arch of your lower back.
