    • Keep you moving and improves your performance
  • The RH Extend is a task chair which has simple adjustments, elegant design and unbeatable ergonomic characteristics. The RH Extend ergonomic chair features the unique pattern of movement that has made RH Chairs famous - three articulation points - at the knee, hip and lower back - positioned to complement the body's own joints. This encourages active sitting, while also assuring complete support of the spine.

    Because the RH Extend is easy to adjust, it is ideal for offices or home working environments where several people use the same chair or where it is necessary to make quick adjustments. All controls are conveniently located on the right while all adjustable parts of the chair are clearly marked.

    Simply choose the options that suit your requirements.

    Standard features include:

    • Adjustable Seat Depth
    • Adjustable Backrest Height
    • Upholstered Seat & Backrest
    • Seat Height Adjustment
    • Movement Tension Control
    • Carpet or Hardfloor Castors

    Please note -  Medium back suits users under 5'6" / Large back suits users over 5'6"

  • RH

  • An RH chair is built to withstand stress and to last. Before it leaves the factory it undergoes rigorous tests and inspections. That is why RH give a 10-year guarantee. Because RH Chairs prioritise quality and the environment in everything they do, they are also certified in accordance with ISO 9001 and ISO 14001.

    Which castors should I choose?

    Carpet castors are designed for soft flooring where there is more friction.

    Hard floor castors have a slight braking system so there is more resistance on solid flooring to avoid chairs gliding too far or too fast.

    Please select the castors for the floor surface you will mostly be using the chair on. 

    Hard floor castors can be used on carpets but the chair may not move very easily and carpet castors can be used on hard floors but the chair will be more difficult to keep still.

    Over time, some marking of the floor will happen no matter which castors you select but protective matting can be bought from many high street retailers.
