“His feet hit the mat, and almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child.” That is Kaitlin Hill, the mother of three-year-old Colton, telling ABC News what happened the day a trampoline park broke her son’s femur. Her warning post was shared 240,000 times. We read it. So did every parent of every child who has been hurt at a trampoline park in Earth since.
At Attorney911, we know that scream. We represent the families who have to hear it. We represent the parent standing at a hospital bedside in Earth watching a surgeon explain what happens when a growth plate is destroyed at age nine. We have spent more than 25 years fighting for families facing catastrophic, life-altering injuries. Our managing partner, Ralph Manginello, has been holding corporate defendants accountable since 1998, with admission to federal courts and a track record of multi-million dollar results.
If your child was injured at a trampoline park in Earth, the first thing you need to hear is this: this is not your fault. You signed the waiver because the line was long and the kiosk was fast. You let your child jump because you wanted them to have fun. The park knew the safety standards. The park knew the risks. The park chose margin over your child’s safety.
What happened to your family wasn’t an accident. It was the predictable output of a system designed to maximize revenue while isolating liability. We are here to pierce that system.
One Bad Landing: Why Trampoline Injuries in Earth are Never Accidents
The commercial trampoline park industry has scaled a product the American Academy of Pediatrics (AAP) has warned against since 1999. They have built industrial-scale “adventure hubs” across Earth, serving thousands of jumpers every weekend. But the physics of a trampoline do not change just because you pay an admission fee.
When your child is airborne at a Sky Zone, Urban Air, or DEFY in Earth, they are participating in a high-velocity activity that relies on precise supervision and equipment maintenance. When that supervision fails, or that equipment breaks, catastrophic injury is the mathematical certainty.
For over two decades, our firm has gone toe-to-toe with Fortune 500 corporations like BP, Walmart, and Amazon. The parent conglomerates behind the big trampoline park chains in Earth don’t intimidate us. We know their playbook because our team includes an attorney, Lupe Peña, who used to sit on the other side of the table defending insurance companies and recreational businesses. He knows exactly which arguments they use to hide behind waivers, and he knows exactly how to dismantle them.

The Physics of the Double-Bounce
The most common way children are injured at parks in Earth is the double-bounce. It happens in two seconds. Your child is pushed off by the rebound just as a heavier jumper lands.
When a 200-pound adult lands on a trampoline bed at the same instant a 50-pound child is pushing off it, energy transfer can multiply the child’s launch force by up to 4x. The child isn’t jumping anymore—they are being catapulted. The child’s bones, joints, and spine are not engineered to absorb that much force on the way down.
ASTM F2970, the industry’s own safety standard, requires trampoline parks in Earth to enforce age and weight separation to prevent exactly this. When an Earth park allows mixed-age jumping on the same court, they are violating a standard they helped write. That is not an inherent risk. It is negligence.
The Truth About Earth Foam Pits
Foam pits in Earth parks look like soft, safe landing zones. The medical literature says otherwise. A 2024 study in Pediatrics (Teague et al.) found that foam-pit injury rates are as high as 1.91 per 1,000 jumper-hours.
The mechanism is often head-first entry. The jumper’s head wedges between foam cubes while the body’s momentum continues, leading to cervical hyperflexion or axial compression. This causes SCIWORA (Spinal Cord Injury Without Radiographic Abnormality)—a pediatric phenomenon where the spinal cord is damaged even if the bones look normal on an initial CT scan.
The industry knows this. Since 2018, major chains have been replacing foam pits with pressurized airbags. If the park in Earth where you were injured still uses a foam pit, they are using an outdated, dangerous feature because it was cheaper than upgrading to an airbag.
If your child was injured in a foam pit or on a court in Earth, call us at 1-888-ATTY-911. The clock is ticking on the evidence.
The Standards They Broke: ASTM F2970 and EN ISO 23659:2022
Most personal injury firms can’t tell you what ASTM F2970 requires of a trampoline park. We can cite it from memory. This standard was written by the trampoline industry to establish a safety floor. When we depose the operations manager of an Earth park, we know their standards better than they do.
We look for violations of:
- Attendant-to-Jumper Ratios: Was there at least one monitor per 32 jumpers?
- Age and Weight Separation: Were toddlers jumping in the same zone as teenagers?
- Foam Pit Maintenance: Was the pit deep enough, or was it compacted and bottoming out?
- Pre-Opening Inspections: Did the staff document a tear in the mat and open the court anyway?
While these standards are voluntary in many states, they establish the duty of care in Earth. We also look to international standards like EN ISO 23659:2022, the mandatory standard across Europe. The US is the only major developed economy without a binding national safety standard for trampoline parks. Chains like Sky Zone, Urban Air, and Altitude in Earth operate to a floor that the rest of the world treats as unsafe.
Our firm has recovered multi-million dollar settlements for traumatic brain injury and spinal cord injury victims. We advance every expense—the expert biomechanist, the pediatric orthopedic consultant, the ASTM compliance specialist. You pay nothing unless we win.

Who is Really Responsible? Piercing the Corporate Stack in Earth
When we say “we sue Sky Zone” or “we sue Urban Air” in Earth, we aren’t just naming a name on a building. We are performing corporate archeology. The trampoline park industry uses a five-layer stack of entities to hide the money and shield the decision-makers.
- The Operator LLC: The local business in Earth that owns the equipment.
- The Franchisee: The group that may own multiple parks.
- The Franchisor: Entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings.
- The Parent Company: Sky Zone, Inc. (formerly CircusTrix LLC), backed by Palladium Equity Partners, or Unleashed Brands, acquired by Seidler Equity Partners in 2023.
- The Private Equity Sponsor: The ultimate money source.
We know how to pierce these layers. We currently litigate a $10 million lawsuit against a major university involving rhabdomyolysis and acute kidney failure—the same catastrophic muscle and organ breakdown we see in Earth trampoline injuries. We know how to hold institutional defendants accountable.
In a recent Kansas case (Damion Collins v. Urban Air), an arbitrator awarded $15.6 million after an adult was paralyzed on a “Wipe-Out” attraction. The arbitrator held the waiver unenforceable because of a “systemic failure” to implement safety changes. Crucially, the franchisor—UATP Management LLC—was held responsible for 40% of the fault.
We don’t settle for the local operator’s limited policy. We go upstream because the money is upstream.
The Waiver is Noise: Why That Piece of Paper Doesn’t End Your Case
The most common thing parents in Earth tell us is, “I signed the waiver, so I probably don’t have a case.” That is exactly what the park wants you to believe.
Texas and many other states have clear limits on what a waiver can actually do.
The Gross Negligence Carve-Out
No waiver in America can release a company from gross negligence. If the park in Earth knew the equipment was torn, or that the court was understaffed, and they let your child jump anyway, the waiver is void. In Harris County, a jury awarded $11.485 million against Cosmic Jump because they found gross negligence after a teen fell through a hole in a trampoline slide.
Parental Indemnity for Minors
In most states (including Texas under Munoz), a parent cannot bind a minor child to a pre-injury waiver. The child’s own right to sue survives your signature. If your child was hurt at an Earth park, your signature on that iPad kiosk may be legally irrelevant to their recovery.
Inadequate Conspicuousness
The “fair notice” doctrine requires that waiver language be visible, bold, and specific. If the important parts were buried in twenty screens of small print on an iPad at a crowded Earth check-in counter, the waiver may fail for lack of notice.
The Delfingen Attack for Spanish-Speaking Families
Muchas de las víctimas de lesiones en parques de trampolines en Earth son niños de familias hispanohablantes. Si firmó el documento en inglés y su idioma principal es español, el caso Delfingen US-Texas v. Valenzuela puede invalidar la renuncia. Nuestro abogado asociado Lupe Peña es hispanohablante nativo y representa a nuestros clientes directamente. Llame al 1-888-ATTY-911.
Don’t let a piece of paper stop you from seeking justice for your child. The waiver is a tactic, not a wall.

Catastrophic Pediatric Injuries: The Medical Reality in Earth
Pediatric bone is biomechanically distinct. It is incompletely ossified and more pliable, with an open growth plate (physis) that can fail under loads that wouldn’t affect an adult.
At Attorney911, we specialize in the specific medical categories Earth trampoline injuries produce:
- Salter-Harris Fractures: A fracture that extends through the growth plate. If not monitored for years, this could lead to permanent limb-length discrepancy or deformity.
- SCIWORA: Spinal Cord Injury Without Radiographic Abnormality. A child’s spine can be injured even when the X-ray looks normal.
- Traumatic Brain Injury (TBI): From impact with concrete, unpadded frames, or other jumpers.
- Vertebral Artery Dissection: Rotational shear during a flip can cause a “spinal-cord stroke.” This was seen in the viral Elle Yona case, where a teen’s backflip resulted in C4 quadriplegia after being initially misdiagnosed as a panic attack.
- Exertional Rhabdomyolysis: If your child has dark, “cola-colored” urine 12 to 48 hours after jumping in an Earth park, this is a medical emergency. Muscle breakdown is poisoning their kidneys. This is the same physiology we are litigating in our active $10M hazing case.
A shattered tibia is not “a broken ankle.” It is a decade of monitoring and a life-care plan that anchors in the seven-figure range. We build the medical evidence to prove it.

7 to 30 Days: The Evidence Clock is Running in Earth
The most important evidence in your case is currently sitting in the park’s manager’s office in Earth. And it is about to disappear.
- Surveillance DVRs at many parks are set to overwrite in as little as 7 to 30 days.
- Incident Reports may be “revised” on the park’s computer system as soon as their risk team sees the severity.
- Waiver Kiosks purge version-history data on a rolling schedule.
- Foam Pits get refilled or rotated within days, hiding the compaction levels that caused the injury.
There is a documented pattern in Earth and nationally of parks instructing employees NOT to call 911. At an Urban Air in Southlake, a parent reported that staff were told to down-play injuries. Every minute the park delays a 911 call is a minute the surveillance gets closer to being deleted.
We send the spoliation letter within 24 hours of your retention. We demand the DVR hard drive, the access logs, and the original, un-redacted incident reports.
As client Chad Harris said, “You are NOT just some client… You are FAMILY to them.” We treat your child’s evidence with the urgency we would treat our own family’s.
Call 1-888-ATTY-911 now. We advance all costs, including the forensic digital examiner to interrogate the park’s hard drive.
Beyond the Trampoline: Ninja Courses, Climbing Walls, and Go-Karts
The modern “trampoline park” in Earth is now a Family Entertainment Center (FEC). They have added Sky Rider ziplines, climbing walls, and go-karts. These adjunct attractions are often more dangerous than the trampolines themselves.
- The Matthew Lu Case: A 12-year-old was killed at an Altitude park in Gastonia after employees failed to secure his harness on a climbing wall. He fell 20 feet onto concrete. The park publicly admitted “human error” and removed the wall.
- The Sky Rider Pattern: Urban Air has seen a pattern of “Sky Rider” zipline strangulations and falls in Georgia, Illinois, Florida, and Nevada.
- The Emma Riddle Fatality: A 6-year-old girl was killed in late 2025 at an Urban Air when her electric go-kart mechanical failure sent her into a wall.
If your child was injured in an adjacent attraction in Earth, we know which manufacturers to sue and which chain-wide patterns to subpoena. We use Federal Rule of Evidence 404(b) to show that these weren’t isolated accidents—they were known, repeated hazards the parks failed to fix.
Why Choose Attorney911: Our 50-State Authority

Frequently Asked Questions About Earth Trampoline Injuries
Can I sue if I signed the waiver in Earth?
Yes. Waivers in Earth and across Texas are voidable for gross negligence, failure to satisfy “fair notice” standards, and because a parent generally cannot waive a child’s direct claim. juror verdicts like the $11.48 million Cosmic Jump award prove that a signed waiver is not the end of the case.
What is a “double bounce” and why is it dangerous?
Double-bouncing is an energy transfer from a heavier jumper to a lighter one. The smaller jumper is effectively catapulted into the air with force they cannot control. This is the #1 cause of pediatric fractures at Earth jump parks.
The park only has $1 million in insurance. Is that all we can get?
No. The primary policy is the floor. Above it sit umbrella layers, franchisor additional-insured coverage, and corporate parent towers. We trace every dollar from the operator LLC up to the private equity sponsors like Palladium Equity or Seidler Equity.
How do I tell if the park in Earth was negligent?
We look for violations of ASTM F2970. Was there one monitor per zone? Were big kids and little kids mixed? Was the foam pit refilled? Was the attendant on their phone? Surveillance video and employee training records are the keys.
How much does a trampoline-park lawyer cost in Earth?
Nothing upfront. We work on a contingency fee (standard 33.33% pre-trial). We pay for all the experts—the biomechanists and surgeons—and you only reimburse us if we win your case.
Are trampoline parks safe for toddlers?
The American Academy of Pediatrics says children under 6 should NEVER use trampolines. Earth parks that market “Toddler Time” are knowingly exposing children to growth-plate fractures that their bodies are not strong enough to handle.
Does the park have to give me the video?
They should, but they often won’t. They may even claim it was deleted. This is why we send a spoliation letter immediately. If they delete video after being on notice, we ask the jury for an “adverse inference”—to assume the video showed exactly what we claim.
What should I do if my kid gets a headache after the park?
This could be a concussion or a traumatic brain injury (TBI). Seemingly minor impacts can have delayed effects on a developing brain. Get a medical evaluation at a Level 1 pediatric trauma center serving Earth.
My kid broke a bone at an Earth park. What do I do?
Call 1-888-ATTY-911. Preserve their grip socks, your receipt, and any photos you have. Do not give a recorded statement to the park’s insurance company. Every word can be used to blame your child for the injury.
What if I didn’t actually sign—the host of the birthday party did?
This is a major “Waiver Gap.” If a host signed a master agreement but you never signed for your own child, the park has NO waiver defense against your family. We subpoena the kiosk logs to prove who actually clicked.
How much is my child’s case worth?
Catastrophic cases in Earth involving paralysis or TBI can reach the multi-million dollar range. Even fracture cases with growth plate damage often settle for $500,000 to $2 million because of the lifelong impact.
Why did the staff tell us NOT to call 911?
This is a documented industry tactic aimed at minimizing liability and discouraging families from creating an official emergency record. If an Earth park discouraged you from calling for help, that is evidence of a reckless management culture.
Is an iPad / kiosk waiver even enforceable?
Many are not. If the system glitched, timed out, or used text-links that expired, the electronic signature may be void under the E-SIGN Act and UETA. We hire digital forensic experts to check the park’s metadata.
Will I be blamed for taking my kid there?
No. Texas abolished “assumption of risk” as a separate defense. The park has a non-delegable duty to maintain safe premises. Any argument about your fault is usually a tactic to reduce the check, but children under 7 are legally incapable of negligence in nearly every state.
How long do I have to do something in Earth?
While the statute of limitations for personal injury in Texas is 2 years (usually tolled for minors), the “Evidence Statute” is much shorter. If you wait more than 30 days, the video that proves the monitor wasn’t watching will be gone.
Should I let my kid go to a birthday party at a park in Earth?
Based on the medical data from the AJR and Pediatrics, the risk of a significant injury is real. If you go, be a “rail parent.” Watch from the edge. Do not trust the 17-year-old monitor with your child’s safety.
