What is the difference between the fold up legs and the screw on legs?

The main difference is in how you set them up and store your bellicon:

Screw-on legs need to be twisted on and off each time you set up or put away your trampoline. It’s quick and easy, but does take a few minutes.

Fold-up legs stay attached to the frame and simply fold flat in one movement, so you can set up and store your bellicon even faster.

Both options are equally stable and safe – it just depends on what’s more convenient for you.
