Keep it Together

OM seating chairs thrive when treated well.
To maintain their good looks and great functionality, observe these guidelines below:
If any parts are missing, broken, damaged or worn, stop using the product until repairs are made using factory-authorized parts.

Occasionally check all bolts, screws and knobs to be sure they are tight.
Lubricate the gas cylinder every 6 months.
Avoid prolonged exposure to direct sunlight, or the fabric color may fade.
For cleaning use water or mild detergent solution only.
If you have any questions or difficulties, please contact your original OM Authorized Dealer for
further assistance and services.

Chair Care

Be sure the gas cylinder is inserted into the mechanism firmly. Improper connection may cause wobbling.
Choose correct casters for different floor surfaces. We have specialized casters, but generally suggest choosing Soft
or Rubbercasters for hard or concrete surfaces, and Hard casters for use on carpet.
Do not stand on footring.
Do not sit on any part of the chair (including arms or backrest) except the seat.
Improper sitting may cause imbalances resulting in bodily injury.
Do not use chair as a stepladder.
Use this chair only for seating one person at a time.
Use this chair for its intended purpose only.
Be sure to sit squarely on chair.
To avoid chair collapse, do not remove knobs or screws.
Properly dispose of packing materials. Do not use plastic as head covering. It may cause suffocation.
Do not use chair unless all bolts, screws and knobs are tightly in place.
Do not use chair on uneven floor surfaces. Always use the chair on flat surfaces to prevent injuries.
OM Seating chairs are designed for normal “commercial use” by persons 275 lbs. or less unless weight capacity
is otherwise stated. Commercial use is defined as a single shift of 40 hours or less in a week.
