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: How do I adjust the gas stem height?
To adjust the height of your seat on your 3Dee, use the lever located on the right hand side under your seat. Release once in desired position.
Q: I have lumbar support in my backrest – how do I adjust this?
Using the lever on the inside of the 3Dee backrest bar on the right, you can continually adjust the curve of the lumbar support to suit your physique and personal preference.
Q: Can the angle of my backrest change?
You can adjust the tension of your 3Dee backrest, which will give some leeway in the movement of the backrest. To adjust the tension, use the butterfly nut under the seat. Turn the butterfly nut anticlockwise about 10-15 times for a softer setting with less tension. Turn the butterfly nut clockwise about 10-15 times for a harder setting with more tension.
Q: My 3Dee chair feels quite loose when moving sideways – is this normal?
Your 3Dee chair comes with a flexible sideways movement, which you can adjust to suit how freely you would like to move. Carefully turn the 3Dee chair and lay it on the backrest. Turn the hand wheel to the left for more sideways movement and to the right for less sideways movement.
Note: We recommend starting off with a setting for reduced sideways movement and later adjusting the setting to provide as much sitting as possible.
