“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. In City of Mansfield, families have heard that scream. They have stood in the emergency bays at Cook Children’s in Fort Worth, watching doctors evaluate a child who left the house for a birthday party and may now face a decade of orthopedic monitoring.
At Attorney911, led by Ralph Manginello with over 25 years of catastrophic injury experience, we have seen what happens when the fun stops and the corporate defense machine starts. We are a firm built on the foundation of high-stakes litigation, from the BP Texas City refinery explosion to our current $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. We handle trampoline injury cases in City of Mansfield not as “accidents,” but as the predictable results of business decisions that prioritized profit over child safety.
Injured at a trampoline park in City of Mansfield? What you do in the next seven days will determine whether your case survives. Most park surveillance systems in Tarrant County overwrite their DVR footage in as little as 7 to 30 days. If your child was hurt at the Urban Air on Walnut Creek Drive or any facility near US-287, the evidence of what actually happened—the attendant staring at a phone, the overcrowded court, the torn mat—is already evaporating. We send forensic spoliation letters within 24 hours of being retained to freeze that evidence in place.
“We Had No Idea”: The Reality of the Trampoline Industry
Kaitlin Hill’s words—”We had no idea”—are a refrain we hear from City of Mansfield parents every week. They didn’t know that the American Academy of Pediatrics (AAP) has formally advised against recreational trampoline use since 1999. They didn’t know that the trampoline park industry actually wrote its own safety standard, ASTM F2970, to create a “floor” for safety that many parks still fail to meet.
In Harris County, a jury recently awarded $11.485 million against the operator of Cosmic Jump after a 16-year-old fell through a torn trampoline slide onto concrete. The park argued that the parents had signed a waiver. The jury found gross negligence—a conscious indifference to a known risk—and awarded $6 million in punitive damages. That is the largest reported trampoline park verdict in the country, and it happened right here in Texas. It proves what we tell every client: that piece of paper you signed at the kiosk is not a wall. It is an insurance tactic designed to make you go away. We don’t go away.
Why Your City of Mansfield Trampoline Injury Case is Different
City of Mansfield sits in the heart of the most saturated trampoline park market in the world. With Urban Air headquartered in Grapevine and Altitude Trampoline Park based in Fort Worth, Tarrant County is the “ground zero” of this industry. When we litigate here, we are taking on the franchisors in their own backyard.
Our team includes associate attorney Lupe Peña, a former insurance defense lawyer who used to represent the very companies we now sue. He didn’t just read the waivers; he helped write the scripts that adjusters use to minimize your child’s pain. He knows which clauses are enforceable under the Texas “fair notice” doctrine and which ones are full of holes. Together, we pierce the five-layer corporate stack: from the local operator LLC to the private equity firms like Palladium Equity Partners (backing Sky Zone, Inc.) and Seidler Equity Partners (backing Unleashed Brands and Urban Air).
Mechanism of Injury: The Physics of the Double-Bounce
The most common catastrophe we see in City of Mansfield involves the “double-bounce.” If a 200-pound adult lands on a trampoline bed at the same instant a 50-pound child is pushing off, the energy transfer can multiply the child’s launch force by up to 4x. The child is not jumping; the child is being thrown.
ASTM F2970 requires parks to separate jumpers by age and weight precisely because of this physics. Yet, on a Saturday afternoon at a park near Lake Ridge High School, monitors often ignore these ratios to keep the lines moving. When a child lands from a multi-person bounce, the force hits their still-developing bones with the impact of a car crash. The result is often a “trampoline fracture”—a buckle fracture of the proximal tibia—or a Salter-Harris growth plate injury.
A growth plate injury at age eight is not just a broken bone. It is a potential decade of limb-length discrepancy and corrective surgeries. Our firm retains biomechanical engineers and pediatric orthopedic surgeons to project those lifetime costs into a comprehensive Life-Care Plan. We don’t settle for the ER bill; we settle for the next 70 years of your child’s life.
The Waiver Architecture: Why the Paper Doesn’t Protect the Park
The park’s insurance adjuster will tell you that because you clicked “I Agree” on an iPad, you have no case. In Texas, that is a legal lie. Texas courts, following the landmark Munoz v. II Jaz Inc. decision, have held that a parent cannot bind a minor child to a pre-injury waiver of their personal injury claims. Your signature might affect our ability to sue for your out-of-pocket medical bills, but it cannot extinguish your child’s right to be made whole for their permanent disability.
Furthermore, we attack the waiver on formation grounds. Under Delfingen US-Texas v. Valenzuela, if your primary language is Spanish and the park presented an English-only waiver without translation or explanation, the “contract” may be void for procedural unconscionability. Lupe Peña speaks Spanish natively and works directly with our Mansfield families to ensure the insurance companies don’t use a language barrier as a litigation shield.
Identifying the Deep Pockets: The National Chain Framework
When a child is hurt at a chain like Sky Zone, Urban Air, or DEFY, most law firms only sue the local operator. We go upstream. We identify the corporate parents: Sky Zone, Inc. (formerly CircusTrix LLC) and Unleashed Brands. We follow the money to the private equity sponsors who approve the cost-cutting measures that lead to understaffing.
In 2023, a Kansas arbitrator awarded $15.6 million to Damion Collins after he was paralyzed at an Urban Air. The arbitrator found a “systemic failure” by the franchisor, UATP Management LLC, and allocated 40% of the fault to the corporate office. We use the Collins precedent to show that the brand-level safety manuals and audit reports are the smoking guns. If the corporate office in Tarrant County knew a location was failing its safety audits and did nothing, they are on the hook for the full value of the injury.
Catastrophic Injuries Beyond the Trampoline Bed
Modern “adventure parks” in City of Mansfield have expanded far beyond trampolines. They now feature climbing walls, ropes courses, and indoor ziplines like the “Sky Rider.” Each of these “adjacent attractions” brings new, lethal risks.
- Climbing Wall Failures: Like the Matthew Lu case in Gastonia, where a harness failure led to a fatal fall onto unpadded concrete.
- Sky Rider Strangulations: A recurring pattern of harness cords tangling around children’s necks, including a 2023 incident in Georgia.
- Go-Kart Malfunctions: The 2025 fatality of Emma Riddle in Port St. Lucie, where an electric kart surged forward despite mechanical failure.
If your child was injured on a non-trampoline attraction, the waiver you signed may not even apply. Many of these waivers are drafted specifically for “trampoline activities” and fail to provide fair notice for the risks of mechanical rides and harness systems. We demand the maintenance logs and software audit trails for these devices on Day One.
The Evidence Clock is Running: What We Do in the First 48 Hours
While you are at the hospital, the park is already investigating. They are talking to the teenage monitors, “revising” the incident report, and checking their surveillance retention. We counter their move with a forensic protocol:
- Cellebrite Extraction: If a monitor was on their phone, we subpoena the device and data records.
- Wayback Machine Archaeology: We capture the park’s website and marketing claims to prove they advertised “safe family fun” while ignoring safety standards.
- 911 CAD Records: We pull the Tarrant County dispatch logs to see how many ambulances have been sent to that address in the last five years.
- UCC-1 Liens: We identify the secured creditors and equipment lenders to find additional pockets of recovery if the local operator tries to file for bankruptcy.
Call 1-888-ATTY-911 now. Our Mansfield-area investigators can be on-site within hours to document the scene before the foam pit is refilled or the broken spring is replaced.
Pediatric Medical Specificity: Beyond “Broken Bones”
We speak the language of trauma surgeons because our cases depend on it. We don’t just allege a “neck injury”; we identify SCIWORA (Spinal Cord Injury Without Radiographic Abnormality)—a pediatric condition where the cord is damaged even if the CT scan looks normal. We don’t just talk about “muscle pain”; we litigate rhabdomyolysis cases where the myoglobin cascade leads to acute kidney failure.
Our current litigation against the University of Houston for rhabdo has given us a deep-bench network of nephrology and emergency medicine experts. If your child has “cola-colored” urine or listlessness after jumping in a 110-degree Texas summer, we know exactly what tests must be run to prove the park’s liability for heat stroke and exertion.
The Moat: Why City of Mansfield Chooses Attorney911
We have gone head-to-head with some of the largest corporations in human history—multinational oil companies, Amazon, Walmart, and FedEx. The private equity groups behind your local trampoline park do not intimidate us. They use the same corporate-defense firms Ralph Manginello has been beating for over two decades.
As client Chad Harris said, “You are NOT just some client… You are FAMILY to them.” We treat your child like our own. We advance every expense—from the $15,000 “Day in the Life” video that makes a jury feel your pain, to the $30,000 biomechanical reconstruction. You pay nothing unless we recover money for your family.
Frequently Asked Questions for City of Mansfield Parents
What should I do if my child got hurt at an Urban Air in City of Mansfield?
Seek medical care at a Level 1 pediatric trauma center like Cook Children’s immediately. Do not sign any “Incident Acknowledgment” or “Medical Payment” forms at the park. Photograph the attraction and the monitor stations before you leave the parking lot. Then, call us. We will send a spoliation letter to the Bedford headquarters and the local operator to save the video.
Can I sue if I signed the waiver at the kiosk?
Yes. Texas law under Munoz v. II Jaz protecting minors, and the Moriel gross-negligence carve-out, mean that the waiver is rarely a final barrier. If the park violated ASTM F2970 or their own operations manual, we can likely bypass the waiver.
How much is my child’s trampoline injury case worth?
Catastrophic cases involving spinal cord injuries or TBI can range from $5 million to over $25 million in lifetime needs. Even fracture cases with growth plate damage often anchor in the $500,000 to $2 million range because of the long-term surgical risk. Every case is unique, and we build yours from a forensic-economic foundation.
How long do I have to sue a trampoline park in Texas?
The legal statute of limitations is two years, and for a minor it is tolled until they turn 18. However, the evidence statute of limitations is much shorter. If you wait more than 30 days to call a lawyer, the video of your child’s accident is likely gone forever.
Why is the park’s insurance company offering to pay our deductible now?
This is the “Med-Pay Trojan Horse.” They offer a small sum—$3,000 or $5,000—hoping you will sign a release on the back of the check that ends your right to seek many millions more for permanent disability. Never deposit a check from a park’s insurer without counsel.
Is the foam pit really dangerous?
Yes. Head-first or feet-first landings into compacted foam (below the 42-inch ASTM fill spec) cause the most catastrophic neck and heel fractures in the industry. Most modern parks are replacing these with airbags because the liability for foam pits has become uninsurable.

Systematic Negligence: It Was Never an Accident
What happened to your child wasn’t random bad luck. It was the output of a system designed to maximize jumpers per hour. When Urban Air or Sky Zone decides to run a “Glow Night” with half the lights and no increase in staffing, they are making a business decision to accept more risk. When Altitude Gastonia chose to leave their rock wall over concrete, leading to the death of Matthew Lu, they made a cost calculation.
Our job is to force them to answer for those calculations. We don’t just litigate; we investigate. We find the former attendants who quit because they weren’t being given breaks. We find the digital edit-trails in the park’s computer system that show where an incident report was sanitised after the fact.
We represent families. We represent children. We represent the parent who stayed up all night in a City of Mansfield pediatric ward, wondering why “fun” had to end this way.
Call 1-888-ATTY-911. The consultation is free. The preservation starts now.
National Standards, Texas Toughness
Most personal injury firms can’t tell you what ASTM F2970 Section 10 requires of a trampoline park. We can cite it from memory—attendant-to-jumper ratios, court spacing, foam pit depth, age-separated jumping zones. When we depose the park’s operations manager in Tarrant County, we know their standards better than they do.
Whether the injury happened because of a defective Jumpking net in your backyard or a supervision failure at a massive adventure park, the architecture of the fight is the same. We have gone toe-to-toe with Fortune 500 corporations and made them pay. The parent conglomerates behind the big trampoline park chains don’t get a special pass. Their fleet of corporate lawyers doesn’t intimidate us.

Detailed Injury Analysis: The Salter-Harris Risk
In City of Mansfield youth sports, parents know that a broken bone is serious. But in a trampoline context, it is often a Salter-Harris Type II fracture of the distal tibia. The fracture line extends through the growth plate (physis). Pediatric bone is biomechanically distinct—incompletely ossified and more pliable than adult bone. Because the growth plate fails at lower loads than the surrounding bone, a simple “bad landing” on a Saturday can result in linear growth arrest.
Most firms call it a “broken ankle.” We call it a potential life of gait deformity and prosthetic lifts. We work with pediatric neurologists and orthopedic specialists to ensure the life care plan captures the full cost of this reality. If your child’s injury includes head trauma, we screen for Diffuse Axonal Injury (DAI)—the shearing of axonal fibers that often doesn’t show up on a standard CT scan but results in academic regression and personality changes months later.
Call 1-888-ATTY-911. Your family is not just a case to us. You are family.

Wrongful Death at the Fun Park
If you have lost a child at a trampoline park, we know that no dollar amount brings them back. But we also know that accountability is the only way to save the next child. Ty Thomasson died in 2012 in Phoenix because his head hit the bottom of a 2-foot-8-inch foam pit. His mother, Maureen Kerley, turned that grief into “Ty’s Law,” making Arizona the first state to regulate this industry.
Your child’s case can do more than recover damages. It can change the way Urban Air, Sky Zone, and Altitude operate in Texas. We will name the decision-makers. We will find out who approved the understaffed shift. We will hold them accountable for the system they built.
Call 1-888-ATTY-911. We are built for this fight.
The Policy Limit Shell Game
“The policy is only $1 million.” This is the first lie an insurance carrier tells the family of a paralyzed child. They hope you don’t look for the umbrella. They hope you don’t notice that the franchisor is an “additional insured” on the franchisee’s policy. They count on you not knowing that the parent company carries a secondary tower that reaches $25 million or more.
We skip the primary adjuster and go straight to the corporate risk management team. We’ve done it with BP. We’ve done it with FedEx. We will do it for your child.

Trampoline-Related Rhabdomyolysis: A Silent Emergency
If your child spent two hours jumping at a Mansfield park during a Texas summer and arrived home exhausted, watch their symptoms closely. If they develop dark-brown, cola-colored urine, they may be experiencing exertional rhabdomyolysis. This is a medical emergency where muscle tissue enters the bloodstream and causes acute kidney injury.
The Manginello Law Firm is uniquely positioned to handle these cases. Our active $10 million lawsuit involving rhabdo pathology means we have already built the medical expert and discovery framework necessary to win. Most doctors don’t look for rhabdo after a park visit—and most lawyers don’t know it’s a litigation category. We do.
If symptoms appear, go to the ER, then call 1-888-ATTY-911.
Why Wait Any Longer?
The DVR overwrites. The attendant transfers. The foam pit refills. The incident report gets “finalized.” What happened to your child wasn’t an accident—it was a business decision. You need a law firm that treats you like family and treats the defendants like the multi-million dollar conglomerates they are.
