US custom-made Yoga Unions Slings are constructed from nothing but rated materials: seatbelt webbing, mountaineering carabiners and parachute buckles. They are very strong! These versatile and adjustable slings will allow you to traction and strengthen at home even without a Yoga wall by using our overdoor supports. You turn your door into a rope wall!

The 2-Carabiner sling has no detachable seat and therefore has only two carabiners.
The 4-Carabiner sling has a detachable seat and therefore has four carabiners. You can use the straps and attach something else to them, or use the seat and attach it alone to something else. More experience is required for this.
If you are travelling and want a lighter sling, the 2-Carabiner will be a better choice.
If you plan to work more regularly and in-depth, you might want the 4-Carabiner sling.
