The Orion office chair has durable black fabric upholstery (100,000 Martindale rubs), and is suitable for all types of offices. The chair is suitable for those who sit for a large part of the working day (8 hours/day). It is equipped with the ergonomic features that a chair needs so that you can sit comfortably even during longer periods of work. The office chair features a synchronous mechanism, which increases the ergonomics of the chair for a more comfortable sitting position. Synchronous mechanism means that the seat and back rest follow the movements of the body synchronously (coordinated) when disengaged. While you lean back, the seat also tilts slightly forward, which helps the body to remain in an ergonomic position. This promotes better posture and reduces tension, especially when sitting for long periods. The chair is equipped as standard with castors for hard floors, an adjustable head rest, adjustable 4D arm rests, an aluminium frame, a safety mechanism, weight adjustment, adjustable seat depth, a height-adjustable back rest, a tilting shell-shaped seat, and inflatable lumbar support, to ensure that you receive the most ergonomic office chair possible. Approved according to EN 1335. The DIN standard EN 1335 for office chairs: DIN EN 1335 is a standard that specifies dimensions, safety requirements, and safety tests for office chairs, such as the adjustability of seat height, seat depth, and back rest. The standard aims to ensure that office work chairs comply with ergonomic and safety requirements to guarantee a healthy and safe working environment.
