Abstract: Outdoor or indoor stand for supporting decorative trees, such as Christmas trees. In this stand, the bottom of a tree trunk is inserted into a cylindrical support vessel medially and orthogonally mounted on the top surface of a base plate. The lower and upper portions of the tree trunk are held by first and second abutment portions. Each of the first and second abutment portions and a support arm portion comprises three members that are separately produced but assembled into and handled in a unit. The stand prevents possible sway of the tree such as due to outside impact, firmly supports any thickness of tree trunk and achieves easiness to handle.
