The P-Sit High Back is a very comfortable office chair with an affordable price tag, approved by the ergonomists at Posturite for healthy working. It’s available in four fabric colours: black, navy, royal blue and red. With a chair back height of 560 mm, this is a great choice if you prefer a higher back chair.

The chair provides a degree of movement when you’d like it, which is important for muscle movement and blood flow, and you can also lock its position.

A key feature of the P-Sit is the independent seat and back angle mechanisms. There are three levers to adjust the chair to suit your body shape perfectly; you can adjust the seat back height, the back angle so that it’s comfortable and upright and the third lever is to put the chair into movement mode. Take a look at the Chair Review in the videos below to see this in action.

The gas stem adjusts the overall height of the chair.

Choose from a range of options and add-ons for your P-Sit High Back chair. You can opt to have a Seat Slide which allows the depth of the chair seat to be independently adjusted. This is ideal if you are a little shorter or taller than average. Choose to add an Inflatable Lumbar Support to provide extra support for your lower back. If you’re looking for a 'draughtsman' chair, select the taller gas stem and a foot ring.

Would you like armrests? Choose if you’d like these to be height and depth adjustable, simply height adjustable or foldaway armrests.

Would you like a headrest? The optional headrest on the P-Sit is height and depth adjustable.

Another great bonus for peace of mind is that there is a 5-year warranty on the structural parts of this office chair.

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.
