Designed for professionals requiring superior comfort and support during extended work sessions, this chair combines Scandinavian engineering with advanced ergonomic technology.

Heavy-Duty Construction and 2PP Ergonomic Technology

Built with a 150kg (23.5 stone) rated gas lift, the Mereo 300 accommodates a wide range of users with exceptional durability. The innovative 2PP (Two-Point-Principle) upright posture and active sitting technology promotes natural body movement while maintaining optimal spinal alignment. This system allows for continuous variation and relief even during movement, helping you maintain concentration and productivity throughout the workday.
