These are usually hung with 1/2" bolts into the ceiling. I think they come with a large plastic bracket (maybe) that takes 4 screws. Our house came with a 1/2" bolt in the ceiling of DS's bedroom.
We got the blue IKEA swing chair, and it only got used when there were visitors.
You will need an electronic stud finder (about $10) and some spackle for repair later (another $10). With proper repair, the hole will not be noticeable.
