Q: How do I adjust the back angle of my RH Logic 400 Elite chair?

There is a row of 3 buttons on the right hand side of your Logic 400 Elite. 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 Logic 400 Elite. 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: I have lumbar support in my backrest, how do I adjust this?

On the back of the RH Logic Elite backrest is a lumbar pump. Use the pump to inflate the lumbar support to optimal comfort. If you need to deflate your lumbar, simply push the button on the pump.

Q: My RH Logic 400 Elite chair didn’t come with a neckrest – can I order one to add on myself?

You can retro-fit a neckrest to your Logic 400 Elite . Simply remove the small plastic tab on top of your backrest and slot the neckrest in.

Q: How do I stop the rocking motion of my RH Logic 400 Elite chair?

There is a tilt lock on the right hand side of your Logic 400 Elite at the back. Turn the handle clockwise to lock the chair. 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?

On the bottom right of your backrest there is a grey handle. Simply pull the handle upwards to adjust the height of your backrest. Once you are happy with the position, push the handle downwards.

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.
