The difference between these two hanging styles really comes down to a personal preference, as both styles are stable for use. The range of motion you can expect from one style to the other will vary due to the nature of the hanging method. For the 2-point hanging style, you will have a freer range of motion (like a traditional porch swing) than you would get with the 4-point style, which offers a bit more control. If you’re concerned about the usage of the product with kids or animals, who tend to to cause a swing that’s bit rougher than is typical, a 4-point hanging style is usually better suited to avoid contact with any surrounding space.
For a 2-point hanging style, you will see the ropes look like an inverted “V”. The rope connects by two points (hangers) in the ceiling – one on each side. This style of hanging will allow a wider range of swinging motion.
For a 4-point hanging style, you will see that all of the ropes are vertical. The rope connects by four points in the ceiling – two on each side. This style of hanging will swing a little less than a swing bed hung by 2-points.
In order to help visualize this for your space, you can view the photos below of swing beds hung in both the 2-point hanging style and the 4-point hanging style:
