Chair Height Adjustment. 

The overall height of the chair can be adjusted by lifting 

the lever located below the seat on the front, right-hand side.

 

Lift your weight off 

the chair allowing it to rise and release the lever at the required height. To lower the 
chairs simply lift this lever and release at the required height.

Synchronised Recline Adjustment. 

The synchronised recline of the seat and back 

is unlocked by rotating the hand control below the seat on the front, left-hand side. 
Please be aware that there is a safety feature that requires you to lean gently into 
the back before it will release. The back can be locked in any of five positions or left 
unlocked to follow your movements. The tension of the recline is adjusted by rotating 
the hand control knob located below the seat on the front, right hand side.  
 
The tension of the recline can be adjusted by twisting the rotary control located 
under the front of the seat on the right-hand side. This tension control slides out for 
easy access. 

Seat Depth Adjustment. 

The seat depth can be adjusted by turning the handwheel 

located on the right hand edge of the seat. Pull the handwheel away from the seat 
and rotate to adjust the horizontal seat position. 

Inflatable Lumbar Support. 

The inflatable lumbar support is adjusted using the hand 

bulb located under the right-hand side of front edge of the seat. Squeeze the bulb to 
inflate and press the button on the bulb to deflate.

Back Height Adjustment. 

The back height can be adjusted by lifting the back up a 

step at a time until the correct positioning of the lumbar support is achieved. When 
the back reaches the top of its travel it will drop back to the start position.

Arm Height Adjustment. 

The height adjustable arms have a lever located under the 

outside edge of the arm pad. Press this in and lift the arm to the desired position. 

Folding Adjustable Arms. 

If the chair is fitted with optional folding adjustable arms 

these have a button located half way down the outside of the post to adjust the 
height and a second button at the bottom to allow the arm to be rotated backwards, 
out of the way.
