ABSTRACT:
A tree stand with adjusting features allowing it to remain level in use. The invention includes two main subassemblies—a lower foot platform and an upper seat platform. The foot platform features a pivotally attached foot rest portion which can be adjusted in pitch. The seat platform includes a rotating seat with a pitch pivot located underneath. The seat's pitch is infinitely adjustable without affecting its rotation about the yaw axis. The seat platform also includes two telescoping climbing arms which the user can grasp when moving the two platforms up a tree. These climbing arms can be stowed once the stand is in position for use.
