A hanging chair must be hung so that it can rotate, so that the hanging chords do not wear thin, and so that one can swing in the desired direction.We have therefore created a ball-mounted ceiling hook with an extension chain for adjusting the height.Screws and special metal plugs included. The supplied screws are designed for masonry only. The Powerhook can be fitted to wood, with your own appropriate wood screws.
