Quick Answer: The Springfree Medium Round R79 is the safest overall backyard trampoline — its springless design puts flexible composite rods below the mat and mounts the net on flexible rods, so there are no steel springs or hard frame in the jump zone. Want that safety for less? The Vuly Thunder 2 uses a similar leaf-spring system from about $770. On a budget, the Skywalker 15’ Round ($398) is the best value from a widely available, ASTM-certified brand, and the Zupapa 15’ ($590) adds a 425 lb per-user rating and a 10-year frame warranty. For the highest, most athletic bounce with no weight cap, the ACON Air 16 Sport HD is the performance pick.
We judge every trampoline on the things that actually keep jumpers safe — enclosure design, ASTM compliance, per-user weight limit, and warranty — not just how high it bounces. Here are our picks for 2026.

By the numbers
- 100,000+ trampoline-related injuries are treated in U.S. emergency rooms each year (CPSC data via University of Utah Health).
- ~66% of trampoline injuries happen on home/backyard trampolines vs. ~34% at trampoline parks (Market.us).
- 75%+ of injuries occur when two or more people jump at once and collide — which is why one-jumper-at-a-time and no-gap nets matter (AAOS OrthoInfo).
- 90%+ of trampoline injuries are to children, most commonly ages 5–14 (Policygenius, AAOS).
- ~$3.75 billion projected size of the global trampoline market in 2026, up from ~$3.28 B in 2023 (Market.us / ElectroIQ).
1. Springfree Medium Round R79 — Safest Overall
Springfree Medium Round R79
- Springless "SoftEdge" design — flexible composite rods sit below the mat, so there are no steel springs or hard frame in the jump zone.
- Net mounted on flexible fiberglass rods: a falling jumper hits soft net, not hard poles.
- 10-year warranty covering the entire trampoline (frame, mat, net, rods); optional tgoma interactive game system.
- No single-user weight cap.
Springfree earns its “world’s safest trampoline” reputation by engineering out the two hardware hazards spring models can’t fix: exposed springs and a rigid steel edge. The R79 (10 ft round, 79 sq ft mat) suits most yards; the O92 oval fits an 8×13 ft footprint while giving a jump surface close to a traditional 10×15. It’s the most expensive mainstream option, but if you have young kids it’s the pick that removes the most risk.
2. Vuly Thunder 2 — Best Springless Value
Vuly Thunder 2
- Springless "Leaf Spring" system — no coiled steel springs, so no pinch points.
- Net mounted inside the frame; available up to a big 17.5 ft (XXL) diameter.
- ~330 lb (150 kg) certified per-user rating.
- 10-yr frame warranty; lifetime half-price replacement parts for registered owners.
If you love the idea of a springless trampoline but not the Springfree price, the Vuly Thunder 2 is the value play. Its leaf-spring design delivers a soft, pinch-free bounce that suits families with mixed ages, and the XL/XXL sizes give big jumping surfaces. You give up some of Springfree’s polish, but you keep the core safety benefit for hundreds less.
3. Skywalker Trampolines 15’ Round — Best Budget
Skywalker 15' Round (with Enclosure)
- Patented "no-gap" net that attaches directly to the mat (net inside the poles), eliminating the mat-to-net gap.
- ASTM-tested; 15 ft round is a big family size widely stocked at Walmart, Target, and Home Depot.
- 275 lb recommended per-user limit; ~1,100 lb total static rating.
- 3-year frame warranty (1-year mat/springs/poles).
For the best price-to-size ratio, Skywalker is hard to beat. It’s a traditional spring trampoline, so you accept exposed springs under the pad, but the no-gap net design closes the mat-to-net gap that catches limbs on cheaper models. A solid, ASTM-certified starter for families watching the budget.
4. Zupapa 15’ — Best Mid-Range Warranty
Zupapa 15' (Saffun / Upgraded 1500-lb frame)
- 425 lb per-user capacity on 12–15 ft models — well above budget rivals.
- No-gap net mounted inside the poles; extra-tall net with foamed poles to the ground.
- 10-year frame warranty; sizes from 8 to 16 ft.
- Ships with a full accessory bundle (ladder, cover, wind stakes).
Zupapa splits the difference between budget and premium. You get a much higher 425 lb per-user rating, a 10-year frame warranty, and a complete accessory kit for well under $600 — the strongest value for heavier or multi-kid households that still want a spring trampoline.
5. ACON Air 16 Sport HD — Best Bounce / Adults
ACON Air 16 Sport HD (Rectangular)
- Rectangular 17×9.8 ft with the highest, most athletic bounce in this group.
- No single-user weight restriction; frame static-load tested to 1,650 lb.
- HD "No Finger Access" mesh net with ultra-high walls and a zipper-free double-layer entry.
- 10 yr frame / 5 yr spring & mat warranty; 100% spare-part availability.
If you have the yard and the budget, ACON is the enthusiast’s choice. The rectangular shape and heavy-duty springs give a controlled, powerful bounce that teens, adults, and aspiring gymnasts love, and there’s no per-user weight cap. It’s a premium spend, but the build quality and parts support are exceptional. See our best trampoline for adults and best rectangle trampoline guides for more athletic picks.
How to choose a trampoline
- Enclosure design comes first. Look for a no-gap net that mounts to the mat or inside the springs — not outside them — so there’s no space to slip through and no hard poles in the fall zone. Springless models (Springfree, Vuly) go further by removing springs entirely.
- Match the per-user weight limit to your jumpers. Budget spring models cap around 275 lb per user; choose 425 lb+ or a no-cap springless model for teens and adults.
- Look for ASTM compliance. Reputable trampolines meet ASTM F381 (frame, mat, and components) and F2225 (enclosures). It’s a baseline safety signal.
- Size to your yard — and leave clearance. Measure the footprint plus a safety perimeter. Round trampolines pull jumpers to the center; rectangles give a higher, more even bounce but cost more.
- Read the warranty carefully. Frame warranties of 10 years (Springfree, Zupapa, ACON, Vuly) signal a trampoline built to last; 1–3 years is typical on budget mats and springs.
The bottom line
For the safest backyard trampoline most families can buy, the Springfree Medium Round R79 is our top pick — it removes springs and hard frame from the jump zone entirely. Want that safety for less? The Vuly Thunder 2 brings the same springless idea from ~$770. If price is the priority, the Skywalker 15’ Round at ~$398 is the best budget buy, and the Zupapa 15’ is the value sweet spot with a 425 lb rating and 10-year frame warranty. Whatever you choose, enforce one jumper at a time — collisions, not equipment, cause most injuries.
