Swivel Chair and Gun Rest

• Problem Statement Tree stands used for hunting
  often have a stationary bar that is part of the
  frame for the stand. This bar only offers
  mediocre assistance to the hunter and only when
  he is aiming straight ahead.
• Proposed Resolution A Gun Rest that would
  swivel from side to side will increase the
  accuracy range of the gun. By attaching a swivel
  chair a hunter could also quietly aim at an
  object.
