This paper reports improvement in affinity of a support system with a new active air mattress from viewpoint of a high tolerance for user's body size. The active air mat allows users, whose forearm girth is from 198mm to 262mm, to wear the support system. The range covers 89% of Japanese population. The rigidity of the air mat's holding is evaluated by comparing accelerations and angular velocity of a wearer and of the exoskeleton when he swings his forearm with the exoskeleton. Besides, it is confirmed that blood flow around the forearm is secured by inflating and deflating air chambers of the air mat sequentially in the same direction of venous flow.
