Vacuum the bed gently with a clean brush attachment. Remove all dust before it has a chance to settle into the upholstery.
Mix lukewarm water with three to four drops of baby shampoo to create a cleaning solution. Dab any stains with a cloth dampened with the solution. Rinse with a cloth dampened with water. Blot dry with a clean cloth.
Avoid direct sunlight, dampness and extremes of heat or cold. The Ralph Lauren website specifies this type of care for all of their beds.
