RH Extend 120 (high synchro back) Ergonomic Office Chair

Price as configured: Ex VAT £624.00 Inc VAT £748.80

The RH Extend chairs are user friendly, durable and ergonomic.

We love this chair as it’s really easy to use, all controls are conveniently located on the right while all adjustable parts of the chair are clearly marked.

One of the many brilliant features of The RH Extend 120 is that it has an adjustable tilt mechanism, this allows the chair to follow the users movement without muscular effort, providing support and encouraging the correct sitting position. It 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.  The RH 100 (medium back height) and RH 120 (high back height) both have this function.

We also offer a free chair set-up by one of our ergonomic consultants with this chair to help adjust the chair to your workstation and needs.
