OrbitFlow mechanism with rocking capability:

• This innovative mechanism lets you rock gently and lock the chair in any of three reclining positions. The ergonomic office chair helps ease muscle tension and supports better circulation while you work.

Ergonomic support for the spine and lower back:

• The lumbar support can be adjusted vertically and horizontally, effectively reducing pressure in the lower back area. This means the ergonomic office chair offers healthy support during long periods of desk work.

Adjustable 3D armrests for comfortable arm support:

• The ergonomic 3D armrests can be adjusted in height, reach and rotation, giving the forearms steady support and making extended periods of work more comfortable.

Adjustable 3D headrest that reduces neck strain:

• The 3D headrest features height adjustment and two-plane tilt adjustment to keep the head and neck stable. It helps limit muscle tension when working from home or at the office.

Convenient clothes hanger:

• The coat hook attached to the back of the frame provides a convenient place for a jacket or blazer. This practical addition increases the chair’s usefulness in both office and home settings.
