“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 on a Saturday afternoon that ended in a body cast. Her warning to other parents was shared 240,000 times on social media. We read it, just like thousands of other parents in Murphy did. It resonates because it captures the exact moment a family’s life changes—a moment that happens inside a system designed to prioritize throughput over pediatric safety.
In Murphy, we see the results of this system every weekend. Families drive down FM 544 or the President George Bush Turnpike to visit Urban Air in McKinney, Sky Zone in Frisco, or the local Ninja Nation right here in Murphy. On paper, it looks like a birthday party or a quick afternoon of exercise. In reality, it is an environment where the American Academy of Pediatrics (AAP) has issued warnings for twenty-five years, and where the industry operates under voluntary standards that they wrote for themselves.
One bounce. One bad landing. One broken neck. That is all it takes. When that moment occurs, the park’s risk management team is already at work before the Robinson Road ambulance arrives. Their goal is to close the file using a kiosk waiver and a $1,500 “medical payments” check. Our goal is the opposite.
At Attorney911, led by Ralph Manginello with over 25 years of courtroom experience, we do not view your child’s injury as an accident. We view it as the predictable output of a business decision. Whether your child was injured at a commercial park in Collin County or on a neighbor’s backyard Jumpking or Skywalker trampoline, we offer the same relentless advocacy that our founder brought to litigation against Fortune 500 giants like BP and Walmart. We bring our firm’s associate attorney, Lupe Peña, who used to defend these very same recreational facilities. He knows their playbook because he helped write it. Now, he uses that knowledge to dismantle their defenses for our clients.
If your child has been injured on a trampoline in Murphy, call 1-888-ATTY-911. Hablamos Español. Our consultations are free, and we advance every cost of your case—including the biomechanical engineers, pediatric specialists, and ASTM compliance experts required to win. You pay nothing unless we recover for you.
Why a Murphy Trampoline Injury Case is Never Just an Accident
The commercial trampoline park industry has scaled a known-dangerous activity to massive proportions. In Murphy and the surrounding North Texas suburbs, we have a higher density of these parks than almost anywhere else in the country. From the Urban Air headquarters in Grapevine to the regional offices of Altitude in Fort Worth, our region is the epicenter of this industry.
When an injury happens at a facility like the Sky Zone Frisco or the Urban Air in McKinney, the defense will immediately point to the “inherent risks” of jumping. We reject that framing. Inherent risks are things a jumper causes themselves on properly maintained equipment. It is not inherent for an attendant to be on their phone while a 200-pound adult double-bounces a 60-pound child off a court. It is not inherent for a foam pit to be compacted so far below the ASTM F2970 requirement that a child strikes the concrete floor beneath.
Our firm is currently litigating a $10 million lawsuit against a major university and a fraternity involving rhabdomyolysis and acute kidney failure. The injury physiology in that case—muscle breakdown following extreme physical exertion—is the exact same pathology we see in children who jump for two hours in 85-degree indoor heat in Murphy with no water. We understand the medicine of these cases as well as we understand the law.
The case that defines the stakes in Texas is Max Menchaca v. Cosmic Jump. In Harris County, a sixteen-year-old fell through a torn trampoline slide onto a concrete floor. He suffered a traumatic brain injury and permanent neurological damage. The jury heard that the park knew about the tear and did nothing. They awarded $11.485 million, including $6 million in punitive damages. The park had a signed waiver. The jury found gross negligence anyway. That is the largest reported trampoline park verdict in U.S. history, and it happened right here in a Texas courtroom.
The Physics of Chaos: How Trampolines Maim Children
We don’t just say the parks are dangerous; we prove the physics of why they are. Most parents don’t realize that a trampoline bed is an energy-storage device.
The Double-Bounce Energy Transfer
The signature mechanism of injury in Murphy trampoline parks is the double-bounce. When a heavier jumper (an adult or a teenager) lands on the mat while a smaller child is pushing off, the kinetic energy from the heavier mass transfers through the springs. This energy adds to the child’s own momentum, multiplying their launch force by up to four times. The child isn’t jumping anymore; they are being thrown by a catapult.
ASTM F2970, the safety standard the trampoline industry drafted itself, recognizes this danger. It requires parks to operationalize age and weight separation. When you see a “toddler time” at a Murphy-area park with twelve-year-olds jumping in the same zone, you are looking at a violation of the industry’s own safety floor.
Foam Pit Submerge-Entrapment
Foam pits look like clouds to a child. To an engineer, they are often a failure of deceleration. ASTM F2970 and the international standard EN ISO 23659:2022 require foam pits to be maintained at specific fill depths—typically at least 42 inches of high-density foam blocks. Over time, those blocks compact. They lose their “fluff.” If the park fails to rotate the blocks weekly or replace them when they degrade, a child entering head-first will slide through the gaps and strike the hard floor.
This produces catastrophic cervical injuries, such as atlanto-axial subluxation and SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). Because the pediatric spine is ligamentous and flexible, the cord can be stretched and damaged even when an initial CT scan in a Murphy emergency room looks normal.
Harmonic Vibration in Connected Courts
Unlike a single backyard trampoline, commercial courts are interconnected. A jump on one mat sends a vibration wave through the metal frame to adjacent mats. This is why kids “just fall” for no reason—they were hit by a harmonic wave from a jumper three mats away. The industry knows this phenomenon exists, yet they continue to design parks with connected beds to maximize jumper count per square foot.
Standards and Foreseeability: What the Park Knew in Murphy
Every defendant in a Murphy trampoline case will claim they didn’t know the risk. We prove otherwise using a thirty-year paper trail of medical and industry warnings.
The American Academy of Pediatrics (AAP) Position
The AAP has had a clear policy statement since 1999: trampolines should not be used at home. This was reaffirmed in 2012 and again in 2019. The medical consensus has been unanimous for a quarter-century. Every manufacturer like Jumpking or Skywalker and every chain like Urban Air or Sky Zone knows this. They sell the product and the experience against the direct advice of the nation’s pediatricians.
ASTM F2970 vs. EN ISO 23659:2022
In the United States, we rely on ASTM F2970, which is a voluntary standard. In Europe, the EN ISO 23659:2022 standard is mandatory and much stricter. We cite these international standards to prove that the U.S. industry’s “safety floor” is actually a basement compared to the rest of the developed world.
When we depose a park manager in Collin County, we don’t just ask if they followed their own manual. We ask why they didn’t follow the binding standards used by their corporate affiliates overseas. We ask why a Sky Zone in London is safer than a Sky Zone serving Murphy.
CPSC Warning Data
The Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System (NEISS) tracks approximately 300,000 trampoline-related ER visits annually. The data shows that injuries at parks are 3 to 4 times more likely to require hospitalization than those in backyards. The chains in our region have access to this data. They know the rates. They just don’t disclose them at the ticket counter.
The Liable Parties: Who is Responsible for Your Child’s Injury?
Most Murphy families assume they can only sue the local park operator. That is exactly what the corporate parents want you to think. We investigate the full 5-layer defendant stack to find the money.
- The Operator LLC: This is the entity that actually runs the park floor in North Texas, often undercapitalized and carrying a $1 million policy.
- The Franchisee: A larger group that may own ten or fifteen locations across Texas.
- The Franchisor: This is Sky Zone Franchising LLC or Urban Air Franchise Holdings. They dictate the training, the layout, and the safety rules. If they failed to audit the local Murphy-area park, they are liable.
- The Corporate Parent: The entity now known as Sky Zone, Inc. (formerly CircusTrix LLC) or Unleashed Brands. These are billion-dollar conglomerates backed by private equity firms like Palladium Equity Partners and Seidler Equity Partners.
- The Manufacturer: If a mat tore (like in the Cosmic Jump case) or a harness failed (like in the Sugar Land Urban Air Ispahani case), we sue the vendor who made the equipment, such as Ropes Courses Inc. or UA Attractions LLC.
For backyard injuries in Murphy neighborhoods, we look at the homeowner (and the attractive nuisance doctrine) but prioritize the manufacturer and the retailer. Under the Bolger v. Amazon and Oberdorf v. Amazon doctrines, we can reach companies like Amazon and Walmart (for their Bouncepro brand) when they act as the seller of a defective product.
Texas Waiver Law: Why Your Signature Is Not a Dead End
The most common reason families in Murphy don’t call a lawyer after a trampoline injury is the kiosk waiver. They believe they signed away their rights.
In Texas, your rights are much stronger than the park’s lawyers admit.
The Munoz v. II Jaz Inc. Rule
Since 1993, Texas law has been clear: a parent cannot bind a minor child to a pre-injury waiver. If your seven-year-old was injured at a park in Frisco or McKinney, your signature on that iPad does not stop your child’s own lawsuit. While it might limit your ability to sue for the medical bills you paid, it doesn’t touch your child’s claim for their pain, their suffering, and their future life care.
The Dresser Fair Notice Doctrine
For an adult’s waiver to be enforceable in Texas, it must meet the “fair notice” test from the case of Dresser Industries v. Page Petroleum. The waiver must be conspicuous (big enough and bold enough to see) and it must satisfy the express negligence rule (it must use the specific word “negligence”). Kiosk waivers that you are forced to scroll past in two seconds rarely meet this standard.
The Bilingual Formation Barrier (Delfingen)
In Murphy and Collin County, many jumping families are bilingual. If your primary language is Spanish and the park only gave you an English waiver on a tablet, the contract may not have been validly formed. Under the Delfingen US-Texas v. Valenzuela doctrine, we have successfully argued that a waiver is void when the signer could not read the document they were pressured to sign.

Catastrophic Pediatric Injuries: Beyond the Initial ER Bill
A trampoline injury at age eight is not the same as an injury at age thirty. The long-term costs are vastly different.
Salter-Harris Growth Plate Fractures
The cartilaginous growth plate at the ends of children’s bones is the weakest point. A Salter-Harris Type II or IV fracture of the tibia doesn’t just mean a cast today. It means the bone that should grow for the next decade might not grow straight. This leads to limb-length discrepancies, angular deformities, and repeat corrective surgeries manifest five or six years after the park visit. We coordinate with pediatric orthopedic surgeons to build a Life Care Plan that accounts for every year of your child’s growth.
TBI and the Developing Brain
A concussion in Murphy youth sports is a serious event; a TBI on a trampoline frame is often permanent. Pediatric brain injuries interfere with the formation of neural pathways. A child who was an “A” student before the injury may struggle with cognitive fatigue and executive function for the rest of their school years. We include educational consultants in our expert team to quantify the cost of specialized instruction and aides.
Exertional Rhabdomyolysis
If your child has dark-brown or cola-colored urine 24 hours after a trampoline park visit, this is a medical emergency. Rhabdomyolysis is the breakdown of muscle tissue that floods the bloodstream with myoglobin. It causes acute kidney failure and can be fatal. Most Murphy ERs will initially misdiagnose it as a “stomach bug” or “exhaustion.” We know the difference. Our firm’s ongoing $10 million UH hazing litigation is centered on these exact medical protocols.
The 48-Hour Evidence Gap: Why You Must Act Now
While your child is in surgery at Children’s Medical Center Plano or Texas Children’s Hospital, the evidence in Murphy is disappearing.
- DVR Overwrite: Most North Texas trampoline parks use surveillance systems that overwrite footage every 7 to 30 days. If we don’t send a certified spoliation demand this week, the video of your child’s injury will be gone forever.
- Waiver Purges: Kiosk databases can purge session logs and version history every 72 hours. We need to capture the exact version of the waiver as it stood on the day you touched the screen.
- Incident Report Revisions: We have seen cases where the “official” incident report produced six months later is much different from the one filled out the night of the injury. We use forensic document analysis to pull the original metadata.
- Attendant Turnover: The turnover rate for court monitors is over 130% per year. The teenager who saw your child get hurt will likely quit within three months. We use our private investigators to find them while they still remember the shift.
The 10-Step Attorney911 Case Build
Most firms wait for the medical bills to arrive before doing the work. We start the day you call.
- Immediate Spoliation Demand: We send a 10-page preservation demand to the park, the corporate parent, and the insurance carrier within 24 hours.
- Scene Investigation: We dispatch investigators to the Murphy-area park to document current equipment conditions and staffing levels.
- Waiver Archaeology: We use the Wayback Machine and forensic tools to see if the park “updated” their waiver after the incident to hide a legal hole.
- Medical Chronology: We don’t just read the bill; we build a day-by-day medical map of the injury and the recovery.
- Corporate Structure Discovery: We identify the deep pockets upstream, finding the umbrella and excess policies.
- ASTM Audit: We cross-reference the park’s operations manual against ASTM F2970 to find every standard they skipped.
- Expert Retention: We hire a biomechanical engineer to model the 4x launch force of the double-bounce.
- Chain-Wide Search: We search for similar incidents at other locations in the Urban Air or Sky Zone chain to prove the park had notice of the hazard.
- Life Care Planning: We calculate the next 70 years of your child’s needs.
- Trial Readiness: We prepare for the courtroom from day one. In Harris County, Cosmic Jump had to pay $11.485 million because the lawyers were ready to show a jury the whole truth.
Frequently Asked Questions for Murphy Parents
Can I sue if I signed the waiver?
Yes. As discussed, Texas law (Munoz) generally prevents you from waiving your minor child’s legal rights. For your own injuries, the waiver is often defective under the Dresser fair notice rules. In every case, gross negligence cannot be waived. If the park knew they were understaffed and let the jumping continue, the waiver is irrelevant.
Should I let the park’s insurance company pay my hospital bill?
Be very careful. This is often called a “Med-Pay” offer. It looks like a gesture of goodwill, but a check for $3,000 often has a full release written on the back in tiny print. Once you deposit it, your million-dollar case is over. Never sign anything or deposit an insurer’s check without letting us read it first.
How long do I have to sue a trampoline park in Texas?
The standard statute of limitations is two years from the injury. However, for a minor under Tex. Civ. Prac. & Rem. Code § 16.001, the clock is “tolled” and doesn’t start until they turn 18. This means a child theoretically has until their 20th birthday to file. Do not wait this long. The evidence and witnesses will be gone within a few months.
What if my child was hurt at a neighbor’s house in Murphy?
These are “attractive nuisance” cases. If a neighbor has an accessible trampoline without a fence or high-quality enclosure, they are liable for injuries to your child, even if your child wasn’t explicitly invited to jump. We look at the homeowner’s insurance policy—many have trampoline exclusions, but we often find coverage in their umbrella policies or bring claims against the manufacturer.
Is the foam pit really safe for my toddler?
No. The AAP 2019 report and the AJR 2024 imaging essay confirm that children under six have the highest risk of “trampoline fractures” and cervical compression in foam pits. If a park in Murphy markets a “toddler time” involving foam pits, they are marketing an activity the medical community has banned for years.
How much does a trampoline lawyer cost?
We work on a contingency fee basis. You pay nothing upfront and nothing out of pocket. We take a percentage of what we win for you at the end. If we don’t win, we swallow the thousands of dollars in expert fees ourselves. Your family’s recovery is the priority.
