“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.” Those words, told to ABC News by Kaitlin Hill after her three-year-old son Colton suffered a broken femur at a trampoline park, resonate with every parent who has ever stood in a trauma bay. For families in Royse City, the drive along I-30 to a nearby adventure park is supposed to end with tired, happy children—not with a life-altering orthopedic emergency.
We understand that you had no idea. We know you would never have let your child onto that court if you had known the physics involved. At Attorney911, we’ve spent more than 25 years holding corporate defendants accountable, and we see the pattern that the industry tries to hide behind kiosk waivers and loud music. Whether your injury happened at the Urban Air in Rockwall, a backyard Jumpking in a Royse City neighborhood, or a school event within Royse City ISD, your family deserves more than an insurance company’s scripted apology. You deserve a legal team that has memorized ASTM F2970, that manages multi-million dollar catastrophic cases, and that knows exactly how to dismantle the “paper shield” the park forced you to sign.
The Reality of Trampoline Injuries in Royse City
Every year in the United States, roughly 300,000 people visit the emergency room because of trampoline-related accidents. In a growing community like Royse City, where youth sports and active play are part of our culture, the concentration of these incidents is often measured in hundreds.
What the marketing materials for national chains don’t tell you is that these injuries are predictable. According to the Teague et al. study published in Pediatrics in January 2024, the injury rate in foam pits is 1.91 per 1,000 jumper-hours. For high-performance “Advanced Skills” jumping, that rate climbs to 2.11. In a facility seeing hundreds of jumpers on a Saturday afternoon, an injury isn’t a fluke—it’s a statistical certainty of the business model.
When your child is hurt, the park manager might point to the waiver. Our managing partner, Ralph Manginello, who has been fighting for injury victims since 1998, has seen this tactic before. We don’t view a waiver as a dead end. We view it as the first document we are going to challenge. In Harris County, a jury awarded $11.485 million against the operator of Cosmic Jump after a teenager fell through a torn mat onto concrete. Even with a signed waiver, the jury found gross negligence. That is the standard of accountability we bring to Royse City.
Why “Accidents” Are Business Decisions
We operate from a single premise: a trampoline injury is almost never a true accident. It is the output of a system designed to maximize margin and minimize floor staff.
The American Academy of Pediatrics (AAP) has warned against recreational trampoline use since 1999. The industry itself wrote ASTM F2970 to establish a safety floor for commercial courts. When a park in the Royse City area decides to staff three courts with one 17-year-old monitor who is more interested in his phone than the jumpers, they are choosing to operate below the standard of care.
Consider the physics of the “double-bounce.” This occurs when a heavier jumper lands just as a lighter jumper is pushing off. The energy transfer can multiply the launch force by up to four times. If your 50-pound child is double-bounced by an adult, they aren’t jumping anymore—they’ve been launched as a projectile at a velocity their bones weren’t meant to handle. ASTM F2970 requires parks to enforce age and weight separation to prevent this. When they ignore that rule to pack more people onto the floor, they have made a business decision to accept the risk of your child’s broken femur.
The Attorney911 Advantage: Internal Knowledge
Our team includes associate attorney Lupe Peña, who used to represent insurance companies and recreational facilities against these very claims. He knows the script the adjusters use because he helped write it. He knows which waiver clauses are full of holes and which ones Texas courts are increasingly skeptical of.
When you call us at 1-888-ATTY-911, you aren’t just getting a lawyer; you’re getting an insider who knows that the “friendly” call from the park’s insurance adjuster 48 hours after the accident is actually a fact-finding mission to build a defense against you. We block those calls. We handle the adjusters. We protect your family so you can focus on the hospital room.
Catastrophic Pediatric Injuries and Growth Plates
In children, a fracture is rarely “just a broken bone.” Because children are still developing, they possess growth plates, or physes, made of cartilage. These are the weakest points of the skeletal system.
A Salter-Harris fracture—the standard classification for growth plate injuries—can have consequences that last a decade. If a distal tibia fracture isn’t monitored correctly, the bone may stop growing or grow at an angle, leading to permanent limb-length discrepancy. We work with pediatric orthopedic surgeons to build life-care plans that look ten years into the future, ensuring that any settlement covers the corrective surgeries your child may need as a teenager, not just the ER bill from today.
The Rhabdomyolysis Bridge
Our firm is currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. This is the same catastrophic muscle and organ breakdown we see in “crush” injuries and extended-jumping cases at trampoline parks.
If your child spent two hours jumping in a hot indoor facility in North Texas and arrives home with dark, “cola-colored” urine or muscle pain that seems impossible, they may be experiencing a medical emergency. The breakdown of muscle tissue releases myoglobin into the bloodstream, which then poisons the kidneys. Most general practice firms don’t understand the complex pathology of rhabdo. We do. We have the medical experts and the litigation experience to prove how a park’s failure to provide adequate hydration and rest intervals led to organ failure.
Waiver Deconstruction: Why You Can Still Sue
It is a common myth in Royse City and across Texas that signing a kiosk waiver means you have no rights. That is simply false. Texas law provides several “attack vectors” that we use to dismantle these agreements:
- Gross Negligence: Waivers in Texas generally cannot release claims for gross negligence. If the park knew of a dangerous condition—like a torn mat or a shallow foam pit—and did nothing, the waiver is often void.
- Parental Indemnity: Under the landmark case Munoz v. II Jaz Inc., a parent in Texas generally cannot sign away a minor child’s personal cause of action. Your choice to let them jump does not extinguish their right to be safe.
- The Dresser Doctrine: The Texas Supreme Court in Dresser Industries v. Page Petroleum established the “fair notice” rule. A release must be conspicuous. If the negligence waiver was buried in 20 pages of fine print on a tablet, it may not be enforceable.
- Signer Authority: Many waivers in Royse City are signed by grandparents, older siblings, or the parents of a birthday party host. Under Texas Family Code § 153.073, only a legal guardian can usually bind a minor. If the wrong person signed, the waiver doesn’t exist.
As Lupe Peña often explains to our families, “El hecho de que haya firmado un papel no significa que el parque tenga derecho a ser negligente con la seguridad de su hijo. Hablamos español y podemos explicarle sus derechos legales sin rodeos.”
The 48-Hour Evidence Window
The clock is running against your case from the moment the EMS unit arrives. Trampoline park surveillance systems are frequently set to overwrite footage in as little as 7 to 30 days. Incident reports can be “finalized”—code for edited by risk management—before you even get a copy.
When you retain us, our spoliation letter goes out to the park, the franchisor, and the corporate parent within 24 hours. We demand the preservation of:
- Multi-angle surveillance footage including the hours before the incident.
- The original, unedited incident report with metadata.
- Attendant shift logs and time-clock records to prove understaffing.
- Maintenance records for the specific foam pit or airbag involved.
- The waiver kiosk database version to check for conspicuousness.
If the park’s video “glitches” at the exact moment of the injury—a pattern seen in the Mathew Knight $3.5 million case in Georgia—we know how to pursue adverse-inference instructions that tell a jury the park is hiding something.
Corporate Archeology: Piercing the Shield
National chains like Urban Air, Sky Zone, and Altitude use a “5-layer stack” to hide assets:
- The Local Operator LLC (often undercapitalized).
- The Multi-park Franchisee.
- The Franchisor (like Sky Zone Franchising LLC).
- The Corporate Parent (Sky Zone Inc. or Unleashed Brands).
- The Private Equity Sponsor (Palladium or Seidler).
They want you to sue the local LLC with a $1 million policy. We go upstream. In the $15.6 million Damion Collins case, the franchisor was held responsible for a “systemic failure” to implement safety changes. We use the same corporate archeology to find the deep pockets needed to fund a lifetime of care for a catastrophic injury.
Common Accident Mechanisms in Royse City Parks
Each attraction has its own failure mode. We investigate them all:
- Foam Pits: These look soft but often bottom out due to compacted foam or inadequate depth (less than the industry-standard fill). This is the primary mechanism for cervical spine injuries and paralysis.
- Sky Riders and Ziplines: We’ve seen a recurring pattern of harness cord strangulations and detachment falls at adventure hubs. If the attendant fails to secure the lanyard, the fall is often to unpadded concrete.
- Climbing Walls: Harness failures are not “human error”—they are systemic training failures. The Matthew Lu case in North Carolina, resulting in a fatality, led the park to admit an employee failed to secure the harness.
- Backyard Trampolines: Our cases often involve Jumpking or Skywalker products where UV degradation has weakened the netting or frame welds have snapped. We also handle attractive nuisance claims where a neighbor’s unsecured trampoline lures a Royse City child into a dangerous situation.

Frequently Asked Questions
Can I sue if I signed the waiver at an Urban Air or Sky Zone in Royse City?
Yes. Generally, in Texas, parental waivers for a minor’s injury are void under Munoz v. II Jaz. Additionally, waivers do not cover gross negligence—such as knowing an attraction was broken and leaving it open. We deconstruct the specific waiver you signed to find the legal opening.
What is a “double bounce” and why is it dangerous?
A double bounce transfers the kinetic energy of a larger jumper to a smaller one through the trampoline mat. This can launch a child with four times the normal force. ASTM F2970 requires age and weight separation to prevent this. When parks allow different sizes to jump together, they are violating industry safety standards.
How long do I have to take legal action in Texas?
The standard statute of limitations is two years from the date of the injury. For minors, this period is often tolled (paused) until they turn 18, meaning they have until their 20th birthday. However, you should never wait. Essential evidence, like surveillance video and witness statements, disappears within weeks.
How much is my child’s trampoline injury case worth?
Value depends on the severity of the injury and the degree of the park’s negligence. Verdicts in these cases have reached multi-million dollar levels, such as the $11.485 million Houston verdict and the $15.6 million Collins award. We calculate damages based on lifetime medical needs, lost future earnings, and pain and suffering.
Does the park have to give me the security video or incident report?
They often refuse to provide it until a lawsuit is filed. This is why our 24-hour spoliation letter is critical—it legally requires them to preserve that data. If they destroy it after receiving our letter, they can face severe court sanctions.
What if my child was hurt at a birthday party hosted by someone else?
If you did not sign the waiver personally, and another parent signed for your child, notice issues arise. Often, a third-party signature cannot bind your child, which completely removes the park’s waiver defense.
Is the “foam pit” really safer than the normal trampoline?
Actually, foam pits are implicated in some of the most catastrophic head and neck injuries. If foam isn’t properly maintained or “fluffed,” it provides uneven resistance. This causes a jumper’s head to stop while their body momentum continues, torquing the spine. Many parks are replacing them with airbags because the liability risk is so high.
What should I do if the insurance adjuster calls me tomorrow?
Politely decline to talk. Tell them you are represented by counsel and have them call our office at 1-888-ATTY-911. Do not give a recorded statement. Every word you say can be used to shift blame to your child.
Why is dark urine a concern after a trampoline park visit?
Dark brown urine after heavy exertion is a primary sign of rhabdomyolysis—muscle breakdown that can lead to acute kidney failure. This is a medical emergency. If your child shows this symptom, go to the emergency room immediately and request a CK blood test.
What if my homeowners’ insurance doesn’t cover my backyard trampoline?
Many policies in Royse City have “trampoline exclusions.” If an injury happened in your yard, we look at the product manufacturer for defects (manufacturing, design, or failure to warn). If a neighbor’s trampoline hurt your child, we may be able to access their umbrella policy or pursue the manufacturer directly.
What does “gross negligence” mean in a trampoline park case?
It means the park acted with a conscious indifference to safety. Examples include ignoring repeated broken-equipment reports, operating at dangerously low staff levels to save money, or refusing to call 911 when a child is clearly in distress.
Can they make my child go to arbitration instead of court?
Parks use “delegation clauses” to try and push cases into secret, private arbitration. Recent 2025 rulings in Texas (Cerna) and Pennsylvania (Santiago) have created a jurisdictional split on this. We use specific attack vectors to keep your case in a public courtroom whenever possible.
How much does it cost to start a case?
Zero. We work on a contingency fee basis. We advance all the expensive expert costs and investigation fees. If we don’t recover money for you, you don’t owe us a dime.
Will I be blamed for letting my child jump?
Insurance companies always try to blame parents. In Texas, the law follows “modified comparative negligence.” As long as the park is found 50% or more at fault, you can recover. More importantly, children under 7 are generally presumed incapable of negligence in Texas. We hold the park accountable for the environment they created.
