Seated massage or Chair Massage is performed with the client seated on a portable massage chair and usually covers the head, neck, shoulders, back, arms and hands. Depending on time constraints oils can be used or massage can be performed over the clothes. The massage can take anything from 10 to 30 minutes. Chair massage reduces muscle tension, calms the nervous system and increases the circulation to boost energy and alertness. This therapy is a cost effective time-out for refreshment and renewal. It is used by a number of corporate clients to improve the productivity of their employees.
