Mechanisms

	Fixed Back The seat will go up and down, the back rest will go up and down and in and out, but you can’t change the angle of the back rest.
	Permanent Contact Mechanism The seat will go up and down, the back rest will go up and down and in and out, and you can fix the angle of the back rest or leave it free floating – in permanent contact with your back.
	Asynchro The seat will go up and down, the back rest will usually go up and down, you can fix or free float the back rest and fix or free float the angle of the seat – independently of the back rest. This lets you find the perfect position to use a computer – even tilting forwards!
	Lock Tilt Mechanism A single lever lets you adjust the seat height up and down and lock or unlock the tilt of the chair. These mechanisms can either be locked in an upright position or left to free float with the user. They all have a torsion control knob to adjust to body weight.
	Synchro The seat will go up and down and you can fix or free float the angle of the seat and back rest together – usually in a ratio of 2:1, so for every one degree the seat tilts, the back rest tilts two degrees. The easy way to find a comfortable position! You can even adjust the torsion control knob to match your body weight. (All of our synchro mechanisms have an ‘anti-shock’ facility which means you aren’t thrown forward when the mechanism is unlocked – reassuring to know!).
	Sliding Seat Mechanism The sliding seat option can be fitted to the Concept Maxi, Smile Maxi, S-Level Maxi, Postura Grandissimo, Posture High Back and Maxi-Ace chairs. It provides seat depth adjustment for different user leg lengths.
	Knee Tilt Mechanism A twin-lever mechanism, the right lever allows you to adjust the seat height up and down and the left lever can be used either to lock the chair in any one of five positions or to tilt with the user. The pivot point is found towards the front of the seat so that your feet remain on the floor when tilting backwards. A torsion-control knob can be adjusted to user body weight and a non-return facility prevents the user from being thrown forward when the mechanism is unlocked.
	Stackable Chair This model of chair is designed to be safely stacked on itself to a maximum of the number shown.

Chair Maintenance

To ensure the structural integrity of your chair is maintained for as long as possible we recommend that the following checks are carried out every two to three months:

All bolts and hand wheels are checked and tightened if necessary.

The adjustability of the chair should be checked to ensure all levers at work and the chair can be easily adjusted to suit the user.

The base and casters are often subject to much neglect. It is important they are checked for any signs of wear or tear and replaced when required.
