Abstract: Apparatus and associated methods may relate to a collapsible tree system having limbs which automatically pivot from a low-profile position while the tree is in a collapsed state to an in-use position when the tree is in an extended state. In an illustrative example, the system may include limb supports movably disposed along a central support. Movement of the limb supports closer together and further apart may cause the limbs to pivot to and from positions. For example, due to limb contact with an adjacent limb support, the limbs may be caused to pivot to the low-profile position. When no forcible contact is present between an adjacent limb support and limb, gravitational forces may permit the limbs to freely pivot to the in-use position. In an illustrative example, each limb support may include a nesting cup for receiving a proximal end of the limbs while in the stowed position.
