Positiv P-Sit Mesh Back Ergonomic Chair
We wanted to develop a chair that was not only ergonomic, fully adjustable and comfortable - but also affordable and simple to use. The result is this: the P-Sit Mesh Back, an office chair perfectly suited to the more petite user.
So what distinguishes the P-Sit from mass-market alternatives? Instead of standard-cut foam, we’ve fitted our chair with a ‘waterfall’ seat specially cut to comfortably support the curves of the human form without restricting the blood-flow in the backs of the legs. We’ve also added basic adjustments with the option to add more if desired, and ensured the chair back is perfectly curved to support your spine correctly and help prevent sitting-related musculoskeletal disorders.
- Choice of 4 colours - black, navy, royal blue and red
- Large double-curved waterfall seat
- Double-curved backrest
- Ratchet backrest height adjustment on all mechanisms
- Lumbar support as standard
- Mesh back
- Black moulded base
- Maximum user weight: 150kg (23.6 stone)
Options
Fabric colours
- Available in black, navy, royal blue and red
Armrests
- Height adjustable armrests
- Height and depth adjustable armrests

Seat slide
- Adds a sliding seat range of 50 mm. Allows the depth of the chair seat to be independently adjusted. If you are short in the thigh you will need to reduce the seat depth so that you can reach the backrest and reduce pressure on the back of your thighs. If you are long in the thigh, seat depth adjustment will allow you to support your thighs correctly.

Q: How do I adjust the back angle of my Positiv P-Sit mesh 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 mesh 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.
