Quick Answer: Choose Vuly’s Thunder 2 ($1,099) if weight capacity matters most — its leaf-spring design rates to 331 lb per jumper, the highest of any springless-marketed trampoline on this site, with a 10-year frame warranty. Choose Springfree’s R79 ($1,449) if you want spring-like hardware removed from the fall zone entirely — its composite rods sit fully below the mat edge, out of sight, at the cost of a lower 220 lb per-jumper rating. Both brands call their trampolines “springless,” but only one actually hides the mechanism; the other just removes the pinch-prone coil gaps while keeping visible hardware at the mat’s edge.
Vuly and Springfree get cross-shopped by the same buyer: someone who’s already decided they want a springless trampoline and is now trying to figure out which “springless” actually means what they think it means. It’s a reasonable place to get confused — both brands use the word, and both remove coiled steel springs from the design. What they don’t share is how far the replacement hardware sits from the jumper, and that difference drives everything else: weight rating, price, and how the two brands’ own FAQ pages describe each other.
Vuly vs. Springfree at a glance
| Vuly (Thunder 2) | Springfree (R79) | |
|---|---|---|
| Springless mechanism | Leaf-spring — flat steel poles flex at the mat edge | Flexible composite rods, mounted fully below the mat edge |
| Hardware visibility at jump level | Visible, but no coil-and-gap pinch points | Not visible — net mounts to the same hidden rods |
| Weight rating (full-size) | 331 lb/jumper | 220 lb/jumper (175 lb on the compact R54) |
| Starting springless price | $1,099 (Thunder 2, 12–14 ft) | $1,249 (R54 Compact, 8 ft) |
| Non-springless entry model | Ultra 2, from $499 (coil springs) | None — every current model is springless |
| Frame warranty | 10 years (Thunder line) | 10 years (every component) |
By the numbers
- 331 lb vs. 220 lb — Vuly’s Thunder 2 per-jumper rating is 50%+ higher than Springfree’s full-size mats, the direct trade-off for keeping the leaf springs closer to the mat edge instead of moving them fully below it (Vuly / Springfree published specifications).
- $1,099 vs. $1,249 — Vuly’s leaf-spring Thunder 2 undercuts Springfree’s cheapest springless model, the 8 ft Compact R54, by $150, despite the Thunder 2 covering a larger 12–14 ft footprint.
- 10 years — both brands back their springless flagship with a 10-year frame warranty, though Vuly’s own Ultra line (traditional coil springs, same brand) drops to just 5 years — see our best Vuly trampoline guide for the full warranty breakdown by model.
- ~100,000+ trampoline-related ER visits happen in the U.S. each year, with roughly 75% involving multiple jumpers at once — a risk both brands’ hardware designs reduce differently on the equipment side, but neither eliminates; one jumper at a time still matters most (U.S. Consumer Product Safety Commission).
Vuly: the higher-capacity springless pick
Vuly Thunder 2 Trampoline with Leaf-Spring Springless Design
- Leaf-spring system — flat steel poles shaped like leaves flex at the mat edge to create bounce, removing the coil-and-gap pinch risk without hiding the mechanism entirely.
- 331 lb (150 kg) per-jumper rating — the highest confirmed figure of any springless-marketed trampoline on this site.
- 10-year frame warranty, 5-year jump mat warranty, 1-year on the safety net, poles and leaf springs.
Vuly’s pitch is removing the specific injury mechanism — pinched fingers and toes in a coil spring’s gaps — without engineering away as much weight capacity as a fully hidden design costs. The leaf springs are still doing visible work at the mat’s edge, just shaped so there’s nothing for a hand to get caught in. Getting a trampoline this size delivered before the weekend?

Springfree: the fully-hidden design
Springfree Medium Round R79 Trampoline with Safety Enclosure
- 10 ft round mat with the springless SoftEdge design — flexible composite rods replace steel springs below the mat edge entirely, and the net mounts to those same rods instead of a rigid frame.
- 220 lb single-jumper rating, 1,500 lb tested maximum static load.
- 10-year warranty covering every component — frame, rods, mat, and net.
Springfree’s composite rods sit far enough below the jumping mat that there’s nothing spring-like left to see at jump level — the trade-off for going that far is the lowest per-jumper weight rating of any premium brand on this site. It’s the pick for households where “no hardware near the jumper” matters more than maximizing capacity.

Which one should you actually buy?
- Heavier teens or adults, or a household near Springfree’s 220 lb cap: Vuly’s Thunder 2. The 331 lb rating gives real headroom Springfree’s full-size mats don’t.
- Want the least hardware possible at jump level, capacity is secondary: Springfree. Nothing spring-like is visible once it’s assembled.
- Tightest possible entry price, coil springs are fine: Vuly’s Ultra 2 ($499) or Lift 2 (~$699) — neither is springless, but both undercut every model on this page.
- Already comparing against a third premium brand: see our ACON vs. Springfree comparison for how a traditional-coil-spring performance brand stacks up against Springfree’s hidden-rod design.
- Either way, don’t skip the fundamentals: full enclosure, correct per-jumper weight rating, and one jumper at a time cut injury risk more than brand choice alone (CPSC/AAP).
The bottom line
Vuly and Springfree both earned the right to call themselves “springless,” but they made different bets on how far to take it. Vuly’s Thunder 2 ($1,099) keeps its leaf springs visible at the mat edge and gets a 331 lb per-jumper rating in return — the higher-capacity buy. Springfree’s R79 ($1,449) moves its composite rods fully out of sight below the mat and caps out at 220 lb per jumper — the more hardware-averse buy. Neither is “more springless” in a way that makes the other wrong; they’re solving for different things at the same price tier. Still deciding on shape or size instead?
