Description

RH Logic 400 Office Chair with Complete Feature Set

The RH Logic 400 delivers professional-grade seating engineered for continuous use environments. Built with a 150kg (23.5 stone) rated gas lift and 2PP (Two-Point-Principle) ergonomic technology, this chair supports active sitting while maintaining optimal posture throughout extended work periods.

Advanced Ergonomic Features

The 2PP technology allows natural body movement without compromising the chair's core support settings. This design reduces fatigue and maintains concentration during long shifts. The inflatable lumbar pump provides customizable lower back support, while the adjustable backrest height accommodates different body types.

Seat adjustments include height (410-530mm) and depth (475-535mm) controls, ensuring proper leg positioning and circulation. The 8E armrests offer three-way adjustment - height (215-295mm above seat), depth, and width - for precise arm support positioning.

Heavy-Duty Construction for 24/7 Operations

Designed for round-the-clock environments, the RH Logic 400 handles demanding workplace conditions. The adjustable tilting resistance controls forward and backward movement, providing stability across different tasks. Choose from three base finishes: silver aluminium, black aluminium, or polished aluminium.
