How to adjust the backrest of an office chair

The method of adjusting the backrest of an office chair usually involves the following steps:

Find the adjustment handle or wrench. These are usually located on the right-hand side of the seat or below the backrest, and may be a knob or lever.

Turn the handle or knob. Gently pull or rotate the wrench to move the backrest to the desired position. If you want to flatten the back of the chair, you may need to find the lever under the right armrest for operation.

Fixed angle. After adjusting to the desired position, release the handle or wrench to secure the angle of the chair back.

Adjust the depth of the backrest. On some office chairs, the depth of the backrest can also be adjusted by pulling or rotating the wrench to ensure comfort.

Refer to the user manual. If you encounter difficulties during the adjustment process, you can refer to the user manual of the office chair or contact after-sales service personnel for assistance.

The adjustment process may vary slightly depending on different office chair models. It is important to adjust according to personal comfort and needs to ensure correct and comfortable sitting posture.
