  • alternative embodiments may include a safety mechanism, for example, a release control, that requires the user to move from the chair to operate the ottoman 700.
  • a safety mechanism may, for example, prevent a user from inadvertently placing his/her foot underneath the top platform 731 in the nursing mode and disengaging the lever 743 from the rod 712.
