Regarding the adjustment of the headrest, please adjust the headrest by pulling up or pressing down.

We have retained a relatively large amount of damping to prevent the headrest from slipping off easily, so under normal circumstances, you need to use a little force to adjust the headrest.

If you find it too tight and adjusting the headrest is inconvenient, you can use some lubricant to make it easier.

About the E part of the chair, twist this knob to adjust the force when adjusting the recline angle of the seat.
