Vuly Thunder 2 vs Springfree

This is the comparison most people reach when they have decided they want the springs away from the jumping area and are choosing how that gets done.
Springfree removes springs entirely: flexible fibreglass rods sit beneath the mat, outside the jumping surface. The Vuly Thunder 2 keeps springs but uses leaf springs mounted away from the mat edge. Both meet the Australian Trampoline Standard AS 4989:2015 and both are round.
Warranty favours Springfree, which provides 10-year frame, mat and net warranties. The Thunder 2 provides 10 years on the frame, 5 on the mat and 1 on the net. The Thunder 2 is rated to 140 to 150 kg per jumper, against 100 kg on full-size Springfree round models.
Price is the other gap. The Thunder 2 starts well below Springfree's round range, and its XXL size is larger than Springfree's Jumbo Round.
Choose Springfree if you want no springs at all and long warranties on every part. Choose the Vuly Thunder 2 if you want a higher weight rating, a larger maximum size, or a lower price.

Quick verdict
Both solve the same problem and both meet the Australian standard. Springfree is the more thorough answer and is backed for a decade on every part. The Thunder 2 gets most of the way there for noticeably less and carries more weight, which suits households with older kids.
