“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 “Kati” Hill, a mother whose warning post after her three-year-old son Colton broke his femur at a trampoline park was shared more than 240,000 times. She told ABC News, “We had no idea. We would have never put our baby boy on a trampoline if we would have known.” We have heard that same sentiment from parents across Tarrant County. Whether you were at an Urban Air in Southlake or an Altitude in Fort Worth, the transition from a Saturday afternoon of “family fun” to the trauma bay at Cook Children’s Medical Center happens in less than two seconds.
If your child was injured on a trampoline in Azle, you are likely feeling a crushing mix of guilt and anger. You signed the waiver at the kiosk because the line was long and the attendant was rushing you. You let them jump because the website promised “safe, healthy fun.” We are here to tell you that what happened to your child wasn’t a “freak accident.” It was the predictable output of a system that puts quarterly profit margins ahead of pediatric safety.
At Attorney911, we don’t handle trampoline cases like a standard “slip and fall.” We treat them as corporate accountability battles. Our founder, Ralph Manginello, brings over 25 years of experience fighting Fortune 500 companies, including the multinational giants involved in the BP Texas City refinery litigation. We know how the parent conglomerates behind chains like Sky Zone, Inc. and Unleashed Brands use corporate layering to hide their assets. We know how to pierce those layers.
Our team includes associate attorney Lupe Peña, who used to sit on the other side of the table. He spent years defending insurance companies and recreational businesses against injury claims. He literally knows the script the park’s adjuster is using when they call you to “check-in.” He knows which clauses in that Azle kiosk waiver are full of holes, and he knows how to use the park’s own safety manual against them in a deposition.
We are currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. This is the exact same catastrophic muscle and organ breakdown we see in children who jump for ninety minutes straight in a hot DFW facility without a hydration protocol. We don’t just know the law in Azle; we know the medicine.
If you are reading this from a hospital bed or a living room transformed by a body cast, call us at 1-888-ATTY-911. We speak your language—literally. Hablamos Español. Lupe Peña speaks with our Spanish-speaking clients directly, without interpreters or delays. You pay nothing unless we win. We advance every cost for the biomechanical engineers and pediatric specialists your case requires. The clock on the park’s surveillance video is ticking. DVRs in these facilities often overwrite in as little as 7 to 30 days. Let us move to preserve that evidence today.
The Reality of Trampoline Park Safety in Azle and Tarrant County
Azle families are surrounded by one of the densest trampoline park markets in the world. With Urban Air headquartered in Grapevine and Altitude Trampoline Park headquartered in Fort Worth, Tarrant County is the ground zero of the indoor jump industry. According to an investigation by the Fort Worth Star-Telegram, there were approximately 500 injuries reported across 21 trampoline parks in the DFW metro over a seven-year span.
When you walk into a facility near Azle, you are entering an environment that exists in a regulatory vacuum. Most parents in Azle assume that because a business is open to the public, a government agency is inspecting the equipment. In Texas, that is a dangerous misconception.
Texas has no statewide statute specifically regulating indoor trampoline parks. Under Texas Occupations Code Chapter 2151, the Texas Department of Insurance (TDI) regulates “Class B” inflatable amusement rides—like the bungee trampolines, indoor zip-coasters (Sky Riders), and inflatable obstacle courses you see inside these parks. However, the law explicitly excludes the main trampoline decks from state oversight.
This means that while the state might check the stickers on an inflatable slide, no one from the state of Texas is checking the mat tension, the spring fatigue, or the foam-pit depth on the main courts. You are relying entirely on the park’s own internal “self-inspection.”
ASTM F2970 vs. The International Standard
The industry tells Azle parents that they meet “industry standards.” We ask: which one?
The American standard is ASTM F2970-22. It was written by the trampoline industry itself. It is a voluntary safety floor, not a mandatory law in Texas. It covers everything from attendant-to-jumper ratios to the required density of foam cubes in a foso. When we depose a park manager in a Tarrant County case, we often find they haven’t actually read the standard their corporate office claims to follow.
Meanwhile, the rest of the world has recognized that voluntary standards aren’t enough. In November 2022, the International Organization for Standardization published EN ISO 23659:2022. This is a mandatory safety requirement across Europe. It covers design, maintenance, and operation with far more rigor than the voluntary U.S. version. Australia mandates its own strict standard, AS 4989:2015.
Sky Zone, Urban Air, and DEFY operate in Azle to a safety floor that the rest of the developed world treats as an unacceptable danger. We use this comparison to prove that the “standard of care” the park claims to follow is actually a choice to prioritize lower operating costs over the safety of Azle children.
Why Your “Signed Waiver” Does Not End Your Case in Texas
The #1 thing we hear from parents in Azle is: “I’d love to hold them accountable, but I signed that electronic waiver on the iPad. I guess I don’t have a case.”
Think again. In Texas, a waiver is often a speed bump, not a wall. We attack these documents on three primary fronts, using specific Texas legal doctrines that we have mastered over 25 years of practice.
1. The Minor-Child Rule (Munoz v. II Jaz Inc.)
This is the most important piece of law for Azle parents to understand. In 1993, a Texas appellate court in Houston decided Munoz v. II Jaz Inc., 863 S.W.2d 207. The court held that a parent cannot unilaterally sign away a minor child’s personal injury claim in advance.
While you may have signed a piece of paper that says you won’t sue, that paper generally cannot extinguish your child’s own independent right to seek compensation for their injuries. If your son or daughter was hurt at an Urban Air or Altitude near Azle, their cause of action usually survives your signature. We have used the Munoz doctrine to keep cases alive that the insurance companies told parents were “closed.”
2. The Gross Negligence Carve-Out (Moriel)
No waiver in Texas can shield a business from gross negligence. Under the Texas Supreme Court’s ruling in Moriel, gross negligence is defined as an act or omission that involves an “extreme degree of risk” which the defendant was subjectively aware of but “consciously indifferent” to.
In the famous Cosmic Jump case in Harris County, a 16-year-old fell through a tear in a trampoline slide and hit the concrete floor beneath, suffering a traumatic brain injury. The park had a signed waiver. The jury awarded $11.485 million anyway—including $6 million in punitive damages—because they found that the park knew about the defect and ignored it. That is the largest reported jury verdict of its kind in the U.S., and it proves that Texas juries will look past a waiver when a park is reckless with a child’s life.
3. The “Fair Notice” and Conspicuousness Doctrine (Dresser)
Texas law requires that a release of future negligence be “conspicuous.” Under the Dresser Industries v. Page Petroleum doctrine, the language must be clear enough to catch the attention of a reasonable person.
If the waiver in an Azle facility was buried in 20 pages of digital legalese, presented on a scratched iPad screen, or if the attendant told you it was just a “sign-in sheet,” it may fail the fair-notice test. Furthermore, under the Delfingen doctrine, if your family’s primary language is Spanish and the park only provided an English waiver without a translation or explanation, we can challenge whether a valid contract was ever formed.
As client Donald Wilcox said, “One company said they would not accept my case. Then I got a call from Manginello… I got a call to come pick up this handsome check.” Don’t let a kiosk waiver be the reason you give up on your child’s recovery. Call us at 1-888-ATTY-911 and let Lupe Peña review the document you signed.
The Anatomy of a Trampoline Accident: Mechanisms of Injury
We don’t just “handle” cases; we reconstruct them. To win a trampoline injury case in Tarrant County, you must understand the physics. We work with biomechanical engineers to model the energy transfer that caused your child’s injury.
The Double-Bounce: A Physics Catastrophe
The most common mechanism of injury in DFW parks is the double-bounce. It happens when a heavier jumper (often an adult or a teen) lands on a trampoline mat at the exact moment a smaller child is pushing off.
The mat stores kinetic energy and transfers it into the smaller jumper. This mass-ratio energy transfer can multiply the child’s launch force by up to 4x. The child isn’t “jumping” anymore; they are being launched like a projectile at a velocity their bones and ligaments cannot absorb on landing.
ASTM F2970 requires parks to enforce age and weight separation. When an Urban Air or Sky Zone allows a 200-pound adult to jump on the same court as a 50-pound child from Azle, they are violating the industry’s own safety standard. That is not an accident—it’s a staffing failure.
The Foam Pit Illusion
Foam pits look soft, but they are consistently the site of the most catastrophic, life-altering injuries.
If a foso isn’t “fluffed” and maintained correctly, the foam cubes compact over time. This leads to “bottoming out,” where a jumper hits the hard concrete or wood floor beneath the foam. Even worse is the cervical hyperflexion that occurs when a child’s head enters the pit first and is abruptly decelerated by the friction of the foam blocks while their body’s momentum continues.
This is how vertebral artery dissections and spinal-cord strokes happen. The viral Elle Yona case on TikTok, which has over 27 million views, documented a teen who attempted a backflip into a foso and ended up with C4 incomplete quadriplegia. He was initially misdiagnosed with a “panic attack”—a common and dangerous error. If your child had a “normal” CT but can’t feel their extremities or has dark urine, they need an MRI and a specialist immediately.
Adjacent Attraction Failures
Modern “adventure parks” in DFW are bolting on ever-more-dangerous equipment:
- Climbing Walls over Concrete: The hardware failure that killed 12-year-old Matthew Lu at an Altitude location was caused by an attendant failing to secure a harness. The park publicly admitted to “human error” and removed the attraction.
- Sky Rider Strangulations: Urban Air’s Sky Rider zipline has seen a chain-wide pattern of injuries, including a 6-year-old girl strangled by a cord in Georgia while her father had to climb the netting to rescue her because no employee intervened.
- Go-Kart Mechanical Failures: The December 2025 fatality of 6-year-old Emma Riddle in Florida followed a go-kart that surged forward without driver input.
These attractions often lack the proper padding required by ASTM F1487 (the playground standard). If your child fell twenty feet onto unpadded concrete at a park serving Azle, the park’s decision to save money on padding is the central evidence of their negligence.
Catastrophic Pediatric Injuries: Why the “ER Bill” Is Not the Full Case
When an Azle child arrives at an emergency room with a trampoline injury, the medical team is looking for several specific, devastating patterns.
Salter-Harris Growth Plate Fractures
Children’s bones are still developing. They have growth plates (physes) that are weaker than the surrounding bone. A Salter-Harris Type II fracture of the distal tibia is one of the most common “trampoline fractures.”
The real danger here is that the damage may not fully manifest for years. A growth plate destroyed at age nine can lead to a limb-length discrepancy or a crooked leg at age fourteen. If you settle your case based only on the initial ER bill, you are leaving your child’s future medical needs on the table. We build Pediatric Life-Care Plans that calculate the cost of a decade or more of orthopedic monitoring and potential corrective surgeries.
SCIWORA and Cervical Trauma
SCIWORA stands for Spinal Cord Injury Without Radiographic Abnormality. It is a pediatric phenomenon where a child’s flexible ligaments allow the spine to stretch and injure the cord even though the bones look “normal” on a standard CT scan.
We work with pediatric neurologists who understand that a child’s spine is biomechanically distinct. We have recovered multi-million dollar settlements for victims of traumatic brain injury and spinal cord injuries—the same categories of harm that tramplines produce.
Rhabdomyolysis: The Myoglobin Cascade
Our active $10 million University of Houston hazing case involves a student hospitalized with rhabdomyolysis and acute kidney failure. We see this same pathology in trampoline cases.
When a child jumps continuously for two hours in a 90-degree indoor facility without adequate water, their muscle cells can literally rupture. This releases a protein called myoglobin into the blood, which clogs the kidneys. If your child has “cola-colored” urine, severe muscle pain, or confusion after a park visit, they are in a medical emergency. The park’s refusal to provide free water or enforce hydration breaks makes them liable for this organ failure.
Learn more in our video guide: “The Ultimate Guide to Brain Injury Lawsuits” at https://www.youtube.com/watch?v=GBYAHi5aiEQ. Our experience in complex medical litigation means we know how to document these injuries so the insurance company can’t dismiss them as “minor.”
The 5-Layer Defendant Stack: Who We Sue for an Azle Injury
Most personal injury lawyers sue the local park and stop. We don’t. We follow the money upstream. A typical trampoline-park tower in Azle has five layers:
- The Operator LLC: The specific entity running the park. They often have the smallest policy.
- The Franchisee: The multi-unit owner who may operate five or ten locations across Texas.
- The Franchisor: Entities like UATP Management LLC (Urban Air) or Sky Zone Franchising LLC. In the Damion Collins case, the franchisor was held responsible for 40% of a $15.6 million award because they failed to implement safety changes across the brand.
- The Corporate Parent: Sky Zone, Inc. (formerly CircusTrix) or Unleashed Brands. These are backed by massive private equity groups like Palladium Equity Partners or Seidler Equity Partners.
- The Equipment Manufacturer: Companies like Ropes Courses, Inc. (the climbing wall manufacturer in the Matthew Lu fatality) or residential manufacturers like Jumpking and Skywalker.
If your child was injured on a Bouncepro trampoline from Walmart or an Amazon Basics model, we can pursue the retailer as the seller under strict product liability doctrine. We have successfully litigated against BP, Walmart, Amazon, and FedEx. The fleet of corporate lawyers hired by a private equity firm doesn’t intimidate us. We’ve already beaten them.
The Evidence Clock: What Must Happen in the Next 7 Days
Every minute you wait to call a lawyer is a minute the trampoline park is using to protect themselves. Evidence in these cases is ephemeral.
- Surveillance Spoliation: Parks routinely “lose” footage of the exact moment of an injury. In a Georgia case (Mathew Knight), the defense surveillance video glitched on four separate cameras at the precise moment of a staff instruction. The jury awarded $3.5 million. We send a 24-hour spoliation letter by certified mail to the park and their general counsel demanding they freeze all DVR footage, access logs, and metadata.
- Incident Report Revisions: We have seen cases where the original incident report says “attendant was on his phone,” but the version produced in discovery is “revised” to say “no staff error noted.” Our digital forensic experts can subpoena the document version history to find the truth.
- Waiver Version Purges: Kiosk databases often purge old waiver versions on a 72-hour cycle. We use the Wayback Machine and forensic capture to prove what the screen actually looked like the day you signed it.
As client Chad Harris said, “You are NOT just some client… You are FAMILY to them.” We treat your child’s evidence as if it were our own. We hire the biomechanist to reconstruct the fall before the park “refills” the foam pit or replaces the broken spring.
Secondary Venues and the “Attractive Nuisance” Doctrine in Azle
Trampoline injuries in Azle aren’t limited to commercial parks. We handle cases arising from:
- Schools and Daycares: The AAP has said since 1999 that trampolines have no place in routine PE classes or daycares. If a daycare in Azle is using a trampoline for children under six, they are violating the standard of care.
- HOA Common Areas: If an HOA in a new Azle subdivision installs a trampoline without proper fencing or supervision, they are liable for the injuries that follow.
- Backyard Attractive Nuisance: Texas law holds homeowners accountable when a trampoline—unfenced and inviting—acts as an “attractive nuisance” for a neighborhood child who wanders onto the property.
Whether it’s a Springfree, an ACON, or a Zupapa, we know the manufacturer IFUs (Instructions for Use) better than the people selling the products. If the net failed or the frame welds broke, that is a product liability case we are ready to file.

Frequently Asked Questions for Azle Families
Can I sue if I signed the waiver at a park near Azle?
Yes, in many cases. Texas courts have voided trampoline park waivers for gross negligence, inadequate conspicuousness (under the Dresser doctrine), and because parents generally cannot waive a minor child’s direct tort claim under Munoz v. II Jaz. Let us review your specific waiver version today.
What should I do if the park manager told us not to call 911?
That is a major red flag and potential evidence of gross negligence. Multiple parents at DFW-area parks have reported being discouraged from calling EMS. If the park minimizes your child’s injury to prevent a 911 CAD record from being created, it is a tactic to suppress evidence. Call us immediately so we can subpoena the EMS dispatch records.
How long do I have to sue a trampoline park in Texas?
The standard statute of limitations for personal injury in Texas is two years from the date of the injury. For minors, the clock is “tolled” until they turn 18, meaning they have until their 20th birthday. However, you should never wait. Surveillance video in Azle facilities is often overwritten in less than 30 days. The case is often won or lost based on what evidence is preserved in the first two weeks.
How much is my child’s trampoline injury case worth?
Every case is unique, but national averages for catastrophic injuries are significant. A permanent cervical spine injury can anchor in the $5M to $25M range due to life-care planning needs. A serious pediatric fracture with growth-plate damage typically settles in the $500K to $2M range. We work with forensic economists to ensure your child’s lifelong earning capacity is protected.
What if my child was injured by another jumper?
The park will try to blame the other jumper (the “Contributory Jumper” tactic). We push back. The park has a non-delegable duty under ASTM F2970 to supervise the courts and separate jumpers by age and weight. The park cannot outsource its safety duty to a seven-year-old child or a distracted parent.
Why is everyone talking about rhabdomyolysis?
Because it is a “silent” trampoline injury. If your child jumped for ninety minutes in a hot indoor court and later has dark, tea-colored urine and extreme muscle pain, they may have kidney failure. We are uniquely positioned to handle these cases because of our active $10M lawsuit involving rhabdo against the University of Houston.
Is the foam pit really the most dangerous part?
By the numbers, yes. Head-first entries into compacted foam pits lead to permanent paralysis. This is why the industry is moving away from foam and toward airbags. If the park you visited still uses a foam pit that looks shallow or compressed, they are using outdated, dangerous equipment.
Do I have to pay anything up front?
No. At Attorney911, we work on a contingency fee. We advance all costs for biomechanical experts, pediatric surgeons, and digital forensics. You only pay us if we recover money for your family. If we don’t win, you owe us nothing.
Can Lupe Peña speak to my family in Spanish?
Sí. El abogado Lupe Peña habla español perfectamente y puede explicarle sus derechos legales directamente. No necesitamos traductores. Llame al 1-888-ATTY-911.
