Q: How do I adjust the back angle of backrest?
There is a lever on the right hand side of your chair with ‘Back Angle’ written on it. Pull this lever up to adjust the back angle of your backrest. Once in a comfortable position, 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?
There is a seat slide wheel on the right hand side of your Positiv Plus. Pull the wheel outwards and turn clockwise to adjust the seat slide forward and anticlockwise to adjust the seat inwards. Once in the desired position, release the wheel to lock in place.
Q: I have lumbar support in my backrest – how do I adjust this?
On the back left hand side of your Positiv Plus there is a lumbar bulb. Pump the bulb to inflate the lumbar. If you wish to deflate the lumbar, press the valve button.
Q: My chair didn’t come with a headrest. Can I order one to add on myself?
Unfortunately, you can’t fit a headrest yourself. However, if you contact our customer services team on +44 (0) 345 345 0010, they will be able to assist in arranging an appointment for one of our install technicians to fix a headrest to your Positiv Plus.
Q: How do I stop the rocking motion of my chair?
There is a lever on the left hand side of your Positiv Plus with ‘Lock’ written on it. Simply push this down if you wish to lock the tilt action.
If you wish to have the tilt motion, simply lift the tab lever and rock backwards. This enables the tilt function to work.
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 backrest handle. Push this handle upwards and adjust the backrest to your desired height. Once comfortable, pull the handle downwards to lock in place.
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.
