Abstract: A seat eliminates any danger of accident during use when attached to a suspended rope. A plate-shaped seat body (1) has an axial passage (3) and a horizontal channel (14) disposed outside of the passage (3). The rope (7) is passed through the passage (3) and has a radial section (16) which is guided over the lower side of the seat body (1) and through the channel (14) and the rope end (17) is passed beneath the radial section (16) to form a knot.

Abstract: A balance training apparatus has replaceable and exchangeable inserts tailored to accommodate various uses and to demand balancing skills of the user in dependence on personal attributes of the user. A moving object is disposed within each of the inserts for directed motion by the balancing user. A window, preferentially made from a clear plastic material, provides for visual observation by the user of the moving object traveling through a respective insert path, such that the user can direct the moving object, preferentially a ball, towards a target or along a path. The window is attached to the house in a manner not requiring the use of tools, such that the user can easily remove the window for direct access to and exchange of the insert.
