Reasons to Buy

The RH Extend is a user friendly, durable ergonomic chair.

The chair is really easy to use, with all controls conveniently located on the right while all adjustable parts of the chair are clearly marked.

The backrest angle of the RH Extend 220 can be adjusted separately, allowing a greater level of user choice ,making this a uniquely adjustable and user-friendly chair.

  • Higher back ergonomic chair
  • Separately adjustable backrest
  • Made from 100% recyclable materials
  • Follows RH’s 2PP chair philosophy of movement
  • Durable base - the RH Extend's base is made of aluminium with black scuff caps for protection
  • Optional adjustable armrests, these can be adjusted vertically, horizontally and rotated to provide full flexibility in supporting different arm lengths
  • Optional adjustable headrest
  • Easily accessible controls
  • Equipped with Twedts cushion providing quality support for the whole upper body. The shape encourages movement and height can be adjusted with a push of a button
  • The Waterfall edge seat reduces pressure on the underside of the thighs to help circulation. The shape keeps the user in the middle of the seat even when pointed correctly forward at the right angle. The seat can be replaced if damaged
  • Soft floor castors for surfaces such as carpet, designed to minimise damage to floor. Hard floor castors for surfaces such as laminate and concrete are restricted in movement once seated to stop the chair rolling away. Please specify hard floor castors when placing your order

Q: How do I adjust the back angle of my RH Extend 220 high back chair?

There is a row of 3 buttons on the right hand side of your Extend 220. Lift the middle button to adjust the backrest angle. Release the button to lock in place. The angle should be set so that your back makes contact with the backrest.

Q: My gas stem seems a little stiff – is this normal?

Sometimes, over time, the gas stem can become a little stiff when trying to adjust the height. A quick and easy fix for this is using WD-40 or Vaseline. Apply a light layer of grease to the gas stem, then try adjusting the gas stem 3-4 times. The gas stem should now adjust easily.

Q: Can my seat slide forward?

There is a row of 3 buttons on the right hand side of your Extend 220. Lift the button furthest back on the right hand side. About four fingers width between the front edge of the seat and the hollow of the knee provides good blood circulation.

Q: How do I adjust the height of my headrest?

Simply move the headrest up/down to adjust to the correct height for you. If you want to adjust the depth of the headrest, turn the knob on the side of the headrest clockwise or anticlockwise, depending on what is comfortable for you.

Q: How do I stop the rocking motion of my RH Extend 220 high back chair?

There is a tilt lock on the right hand side of your Extend 220, at the back. Turn the handle clockwise to lock your Extend 220. To unlock, simply turn the handle anticlockwise.

If you want to adjust the tension of the tilt motion, use the front handle under the right hand side of your seat. Turn anticlockwise for firmer tension and clockwise to loosen the tension.

Q: We have hot-desking and I want to adjust the backrest height – how do I do this?

There are 2 buttons on the right hand side of your backrest. Press the bottom button to adjust the backrest into the desired height. Lock in position by releasing the button.

Q: My seat has become worn over time – can I just swap a new one for the old one?

Yes, swapping the seat pad is simple. Once you receive your new seat pad, pull off the old worn seat pad. You will notice there are holes underneath around the edge of the seat pad. Simply align these to the seat shell, then push down on the edges to secure the seat pad into place.
