The seat angle remains constant while the back angle opens up, using a patented recline action that pushes you "uphill." This unique motion improves circulation and keeps you comfortable throughout the day. 

The synchronized motion of the back and seat is balanced in perfect harmony, ensuring that your body remains supported at all times.

Another key feature is the Variable Back Resistance. The OM5 is designed with a Virtual Lock system, which provides firm lumbar support when your lower back is fully seated.

This system allows for effortless and comfortable pauses at any backrest angle. By leaning your shoulders into the backrest, you can easily recline, while the lower half of the backrest provides stability and holds you upright when needed.

Design and Aesthetics

The Office Master OM5 has a modern design that fits well in most office settings. It offers a range of color options like Arctic White, Modern Black, and Palladium Grey, allowing you to match it with your office decor.
