Once you decide where you want to hang the chair, locate the spot on the ceiling where you need the bolt to be secured. If it within a few inches of a ceiling joist (usually a 2 X 4 or 2 X 6 board that the ceiling is attached to), use a use a bolt with a hook or enclosed circle on the end and attach it to the ceiling joist. Either drill a hole through the entire joist and use a bolt with nut on the end, or use a bolt with a pointed screw end. If you're nowhere near a ceiling joist, you can span two joists, similar to how a light fixture is secured between two joists. You'll need a longer bolt to screw through the ceiling and the cross-board. Once secured (either method), hang the chair onto the bolt protruding from the ceiling.

Good luck
