The swing comes with a large screw about 5" long that can be attached very securely to the ceiling if you can locate a stud spanning the length of the room.
Just be sure of what you're screwing into, you DONT want this thing coming out of the ceiling, it will likely land you in the ER if it were to fall.
I found a stud in our ceiling and pre drilled a hole in the wood as the lag screw provided is rather large (with good reason) so that the threads would not split the wood and lesson the grip that the screw has on the ceiling. We cover the hook with a Chinese lantern that hangs from the hook when not in use.
If you're a renter, or in doubt, you may just want to get the stand... though the hole in the ceiling is small and can be patched with minimal effort.
