With regular care and maintenance, your Herman Miller Cosm chair will provide many years of superior performance and satisfaction. To maintain quality, please follow the cleaning procedures outlined here.
Base, Frame, and Armpads
Wash surface with a soft cloth soaked in mild detergent and warm water. Rinse thoroughly and dry with a soft cloth.
Do not use solvents or abrasive kitchen cleaners.
Intercept™ Suspension Material
Vacuum fabric as needed using an upholstery attachment. Vacuuming picks up dust and reduces the need for professional cleaning.
Do not brush fabric or use a vacuum attachment with a rotary brush. Brushing may permanently damage the nap or change the character of the fabric.
Do not apply water or any liquid solution. Wetting the fabric with any liquid solution may result in permanent damage.
Spot cleaning
Immediately soak up the stain with a soft absorbent cloth.
Do not dry the stain completely or it may set. The longer a stain is allowed to remain on a fabric, the more difficult it is to remove.
For Water-based stains such as coffee, soft drinks, fruit juices, or milk, use a water-based cleaner (specifically made for cleaning fabric) or a solution of mild warm soapy water (not overly soapy) applied with a damp clean cloth or sponge.
Work the cleaner into a lather or foam.
Soak up all remaining solution and then use a clean cloth or sponge dipped in cool water to remove any residue.
Never use hot water; it will set the stain. Avoid scrubbing.
For oil-based stains such as lipstick, grease, or salad dressing, use a dry cleaning solution applied with a damp clean cloth or sponge.
Test the cleaning solution on a small, concealed area first. If there is no spotting, ringing, or damage to the fabric or its dyes, apply the cleaning solution to the soiled area with light, quick strokes.
Begin at the outside of the stain and work toward the center, being careful not to over-saturate the fabric. Do not over apply water or any liquid solution to fabric.
Excessive wetting of the fabric with any liquid solution may result in permanent damage to the material.
Do not rub too vigorously or you may damage the nap of the fabric or break fibres. Several light applications are better than one heavy application.
Soak up all remaining solution and then use another clean cloth or sponge dipped in cool water to remove any residue. Let fabric dry thoroughly and then vacuum well before using.
If the stain resists cleaning, contact a professional cleaner.
