To lower a chair equipped with a single control lever, you typically engage the height adjustment mechanism by moving the lever and then apply weight to the seat.
Based on how these mechanisms function and referencing the provided information:
A one lever mechanism has a seat height adjustment and most chairs also come with a synchronised seat back tilt that can be locked with the same lever. Move it up and down to change the seat height and in and out to lock the back tilt.
The key action for seat height adjustment is moving the lever "up and down". To specifically lower the chair, you will usually:
- Sit on the Chair: Ensure you are seated on the chair. Your body weight is necessary to compress the gas lift cylinder when lowering.
- Locate the Lever: Find the single control lever, typically located on the right-hand side underneath the seat.
- Engage Height Adjustment: Move the lever up or pull it upwards. The reference states moving it "up and down" is for changing height, and pulling or lifting the lever usually activates the gas lift mechanism on standard chairs.
- Apply Weight: While holding the lever in the engaged position (up or pulled), apply gentle pressure downwards with your body weight. The chair will begin to lower smoothly.
- Release the Lever: Once the chair reaches your desired height, release the lever. This locks the chair at that new lower position.
Understanding the Mechanism
Single-lever chairs often utilize a gas lift cylinder for height adjustment. When you move the lever to engage the mechanism while seated, you allow pressure to release from the cylinder, and your weight pushes the piston down, lowering the seat. When you lift the lever while not seated, the gas pressure extends the piston upwards, raising the seat.
The same lever, according to the reference, can also control the back tilt lock by moving it "in and out" or forward and backward, separate from the "up and down" motion used for height.
Quick Guide to Lowering
Here's a simple breakdown:
| Action on Lever | Result |
|---|---|
| Move Up | Engages Height Adjustment |
| Apply Weight | Chair Lowers |
| Release Lever | Locks Height at New Level |
This straightforward process makes adjusting the height of your office chair or task chair quick and easy using just one control.
