Q: How do I adjust the back angle of my Positiv Me 400 extra high back chair?

On the right hand side of your Positiv Me 400 there are 3 levers. The lever closest to your backrest adjusts the back angle. Lift the lever and adjust to a comfortable position. Once happy, release the lever to lock in place.

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?

On the left hand side of your Positiv Me 400, you will find the seat slide lever. Lift the lever until you are happy with your position, then release the lever to lock in place.

Q: I have lumbar support in my backrest – how do I adjust this?

On the back of your Positiv Me 400 backrest there 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 valve button on the pump.

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

Your backrest is on a ratchet height adjustment system. Simply lift the backrest to adjust the height of it.

Q: My seat pad is worn from years of use – can I just swap a new one for the old one?

You can swap the pads over. However, you will need to contact our customer services team on +44 (0) 345 345 0010 to arrange this, as this will need to be completed by one of our install technicians.
