Promotes good posture and protects your back.
The Chair Plus moves with your body, giving you the freedom to stay mobile instead of locking you into one fixed sitting position. With four lockable backrest positions, you can easily switch between focused work and a laid-back position.
In Flex mode, you can adjust the recline resistance to suit your preference. The synchronous mechanism supports a healthy posture, even when you lean back, so you stay well-aligned in every position while naturally reducing pressure on your spine.
For even greater comfort, the extra-padded 2D lumbar support can be adjusted in both height and depth to fit the natural curve of your spine. It helps engage your back muscles, prevents pressure in the wrong areas, and provides support exactly where you need it most.
