This can be used to hang the Moonchair. It’s small, it’s simple and it’s cheap.
How to hang a chair from a ceiling joist or any other wooden part of your house. Drill a 10mm hole and screw it in.
Please note that whilst this ceiling hook is quite strong enough to take your weight, it must be fixed well into a beam or joist that is also up for the job. When fixing into a hidden joist, eg, one covered with plasterboard as in most modern houses, care should be taken to ensure the hook is centred in the joist. If in doubt get a mate who’s a bit handy to do the job for you.
