Q: How do I adjust the back angle of my Positiv P-Sit high back chair?
On the right hand side of your Positiv P-Sit there is a lever. Lift this to adjust your backrest angle. Once you are comfortable, release the lever to lock the back angle 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 P-Sit you will find the seat slide adjustment. 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 your P-Sit 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 valve button on the pump.
Q: How do I stop the rocking motion of my Positiv P-Sit high back chair?
There is a tilt lock on the left hand side of your Positiv P-Sit. Push the lever down to lock the tilt motion.
Q: We have hot-desking and I want to adjust the backrest height – how do I do this?
Your Positiv P-Sit backrest works using a Ratchet Back Height Adjustment. Lift the backrest to adjust the back higher. Once it reaches the top, the backrest will fall to the bottom (the lowest setting).
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.
