To view the Ambi chair user-adjustment video,
Seat Height
Lever on right side
Tilt Tension
Knob under seat at front of chair
To raise: While raising your weight off chair,
lift lever.
To lower: While seated, lift lever.
To increase tension: While seated, turn knob
to the left.
To decrease tension: While seated, turn knob
to the right.
Depending on the desired tilt resistance, a
number of turns may be required.
Adjust chair height so feet rest flat on floor
or footrest. Avoid dangling legs, which puts
pressure on the back of thighs and restricts
blood flow. A work surface or keyboard that
seems too high or low may require adjusting.
Increased tilt tension provides more stability
and back support while you recline. Too
much resistance may make it difficult to
recline. Depending on weight and preference,
different people will require different levels
of tilt resistance.
Tilt Lock

Forward Seat Angle
Locking knob on front left side
To lock chair in upright, semireclined,
or fully reclined position: Sit upright or lean
back to desired position. Pull knob until you

Lean forward to unlock.
Tilt lock allows you to lock chair in a fixed
position for the extra stability that some tasks
may require.
Forward tilt is used to support computerintensive work. This position also helps the
body achieve a more neutral, open angle
between trunk and thighs. Typically, when
forward tilt is used, chair height is increased.

To raise or lower back: While seated, press
button in. Raise or lower back to the desired
position. Release button.

pull lever out and hold. Slide seat forward
or backward by shifting your weight.
Release lever.
Adjust back height of chair so that it comfortably supports the natural curve of your spine.

comfortably supported and seat cushion is
not in contact with back of legs.
