wherein a step of estimating the user's weight includes a step of estimating the user's weight as the first value if a measured period of supplying the air from the first state of the air cell to the second state of the air cell is a third period; and
a step of estimating the user's weight as the second value if the measured period of supplying the air from the first state of the air cell to the second state of the air cell is a fourth period, the first value is larger than the second value, and the third period is longer than the fourth period.
