The RH Extend chairs are user friendly, durable and ergonomic
They are easy to use, with all controls conveniently located on the right while all adjustable parts of the chair are clearly marked.
The RH Extend 100 has an adjustable tilt mechanism which allows the chair to follow the user's movement without muscular effort, providing support and encouraging the correct sitting position.
The 100 version of the RH Extend has a low back and uses a synchro mechanism so the backrest and seat angle move simultaneously when moving. The chair maintains its basic settings regardless of forward and backward movement or lock and release of the tilt mechanism. Both the RH 100 (medium back height) and RH 120 (high back height) have this function.
