adjusting a height of the subject support platform using the lifting mechanism such that the subject support platform may be slid along a top surface of the person support apparatus;
moving the subject support platform from the first position to the second position, wherein when in the second position, the subject support platform is disposed between the subject and the person support apparatus;
extending the first extension platform and the second extension platform away from the subject support platform; and
moving the subject support platform from the second position to the first position with the subject disposed thereon.
10 . The method of transferring a subject according to claim 9 , further comprising:
rotating the first extension platform and the second extension platform with respect to the subject support platform.
11 . The method of transferring a subject according to claim 10 , wherein rotating the first extension platform and the second extension platform with respect to the subject support platform comprises inputting a user input into a control system coupled to the first extension platform and the second extension platform to cause the first extension platform and the second extension platform to be rotated.
12 . The method of transferring a subject according to claim 10 , wherein rotating the first extension platform and the second extension platform comprises rotating the first extension platform and the second extension platform from a substantially horizontal configuration to a chair configuration.
13 . The method of transferring a subject according to claim 9 , wherein adjusting the height of the subject support platform comprises inputting a user input into a control system coupled to the lifting mechanism to cause the lifting mechanism to adjust the height of the subject support platform.
