Karo’s Free-Float mechanism is the ‘heart’ of all our Orthopedic office chairs. What is an orthopedic chair?

The free-float swivel & tilt mechanism gives you total freedom to adjust the backrest and seat of your office chair in a position that best suits your body. 

With a free-float office chair mechanism, the angle and height of the backrest, as well as the seat inclination can all be adjusted independently from each other.

With a free-float office chair mechanism, the angle and height of the backrest, as well as the seat inclination can all be adjusted independently from each other.

A Free-Float mechanism has the following ergonomic benefits:

    • Independent Adjustment. The backrest position can be adjusted independently of the seat tilt angle.
    • The seat angle can be set at a negative tilt (forward sloping), to create an ‘open’ angle at the hips of approximately 100 degrees. This ‘open’ angle is regarded as the ideal ergonomic seated angle – see The Perfect Ergonomic Office Setup for more information.
    • Dynamic back support. In the free-float position, the chair is dynamic and the backrest provides continual back support by remaining in contact with your back and moving with you.
    • Tension Adjustment. A tension adjuster allows you to adjust the amount of tension required to suit your body weight.
    • Locked or Free-Float. You can lock the movement of both the seat and the backrest independently and in any position, or allow them to free-float.
    • A Free-Float mechanism allows for Dynamic Sitting.

The seat angle can be set at a negative tilt (forward slope), to create an ‘open’ angle at the hips of up to 100 degrees. An ‘open’ seated position reduces stress in the lumbar region of the back.
