Imagine a Saturday afternoon at an Urban Air or Sky Zone near Carrollton. The music is loud, the courts are at capacity, and dozens of birthday parties are operating simultaneously. You watched your child step onto the court, wearing the required grip socks and a neon wristband, after you tapped “I Agree” on a terminal that dozens of other parents were waiting to use. Within minutes, the atmosphere changed from laughter to what one Texas mother, Kaitlin “Kati” Hill, famously described to ABC News as “the worst scream that you could ever have heard from a child.”
Her son, Colton, was just three years old when his knees buckled on a trampoline mat during a “Toddler Time” session. It wasn’t a freak accident. It was physics. A heavier jumper landed on the same mat, transferring rebound energy that snapped Colton’s femur—the strongest bone in the body. Kati later wrote, “We had no idea. We would have never put our baby boy on a trampoline if we had known.”
We write this guide because parents in Carrollton deserve to have that idea before the ambulance is called. Since 1998, Ralph Manginello and our team at Attorney911 have stood with families across Texas who are facing the life-altering aftermath of a catastrophic injury. We don’t see these as “unfortunate accidents.” In our experience, a trampoline injury is almost always the result of a business decision. When a park in the Carrollton area decides to staff its courts at half the ratio required by industry standards to protect its profit margins, they aren’t just being “busy.” They are choosing to accept a known risk to your child’s spine, brain, and limbs.
If you are reading this from a hospital bed at a Level 1 pediatric trauma center like Children’s Medical Center Dallas or Cook Children’s, you probably have two pressing questions: How did this happen? and Can I sue if I signed that waiver?
We have the answers. Our firm includes an attorney, Lupe Peña, who used to represent the insurance companies and recreational facilities we now fight. He knows their playbook because he helped write it. We know that the piece of paper you signed at the kiosk is not the total shield the park’s manager wants you to believe it is. From the $11.485 million verdict against Cosmic Jump in Harris County to the $15.6 million arbitration award against Urban Air, the law is increasingly clear: corporate negligence cannot be hidden behind a click-wrap agreement.
The Reality of Trampoline Injuries in Carrollton and North Texas
Nationally, trampolines send more than 300,000 Americans to emergency rooms every single year. The American Academy of Pediatrics (AAP) has been warning parents about the dangers of both backyard and commercial trampolines since 1999, with major policy reaffirmations in 2012 and 2019. Despite these warnings, the industry has exploded in North Texas. Between Grapevine (home to Urban Air’s headquarters) and Fort Worth (home to Altitude Trampoline Park’s headquarters), our region is the absolute epicenter of the trampoline park industry.
A major investigation by the Fort Worth Star-Telegram uncovered a staggering 500 injury reports at just 21 trampoline parks in the DFW metro area over a seven-year period. In Carrollton, families have immediate access to major chains like Urban Air, Sky Zone in Irving or Frisco, and Altitude in Richardson. While these facilities market themselves as “Safe Family Fun,” the data suggests otherwise.
In January 2024, a landmark study published in the journal Pediatrics by Teague et al. prospectively tracked 13,256 trampoline-park injuries. The findings were chilling:
- Overall injury rate: 1.14 per 1,000 jumper-hours.
- Foam-pit injuries: 1.91 per 1,000 jumper-hours.
- High-performance jumping: 2.11 per 1,000 jumper-hours.
These aren’t just twisted ankles. According to a 2024 pictorial radiographic essay in the American Journal of Roentgenology (AJR), up to 1.6% of all pediatric emergency department trauma visits in the United States are now related to trampolines. We see the results in our practice: shattered growth plates, cervical spinal cord injuries, and traumatic brain injuries (TBI) that don’t fully manifest their cognitive damage until the child is struggling in school months later.
Why “Accidents” at Carrollton Trampoline Parks Are Systemic Failures
We don’t argue negligence in the abstract. We prove it by citing the very safety standards the industry wrote for itself. ASTM F2970 is the primary standard for commercial trampoline courts. It wasn’t written by government regulators; it was drafted by the industry to prevent exactly what happened to your child. When we investigate a case in Carrollton, we look for four specific systemic failures:
1. The Understaffing Decision
ASTM F2970 requires a specific attendant-to-jumper ratio. When a park in Carrollton has 60 kids on the floor and one sixteen-year-old monitor who is more focused on his phone than the court, the park is in direct violation of the standard of care. We subpoena shift schedules and time-clock records to prove the park was operating below the safety floor it claimed to follow.
2. The Failure of Age and Weight Separation
The physics of a trampoline are brutal. When a 200-pound adult lands on a bed while an 80-pound child is pushing off, the energy transfer moves through the mat and launches the child with a force multiplied by up to 4x. This “double-bounce” mechanism is the most common cause of pediatric femur and tibia fractures. ASTM F2970 requires parks to enforce age and weight zones. If the monitor at the Frisco or Irving Sky Zone allowed a teenager to jump in the toddler zone, that isn’t a “mistake”—it’s a breach of a non-delegable duty.
3. The Foam Pit Compaction Hazard
Fosos de espuma (foam pits) are advertised as soft landing spots. But foam blocks compact over time, losing their ability to absorb impact. If the pit hasn’t been “fluffed” or refilled per the ASTM maintenance cadence, a jumper can strike the hard floor beneath. This is the mechanism that caused Ty Thomasson’s death in Phoenix, where the pit was only 2 feet 8 inches deep instead of the recommended 6 feet. It’s the same mechanism behind the $3 million settlement in the Anthony Seitz v. AirMaxx case.
4. The Staff Training Gap
Most court monitors are 16 to 19 years old, earning minimum wage, with an annual staff turnover rate exceeding 130%. In many parks, “training” consists of a two-hour orientation video. Washington State’s Department of Labor and Industries (L&I) recently fined Sky Zone locations in Tukwila and Vancouver for child-labor violations, proving a pattern: if a company will break the law to overwork its teenage staff, it will certainly cut corners on training them to keep your child safe.
The Waiver Defense: Why You Probably Still Have a Case in Texas
The question we hear most often from Carrollton families is: “But I signed the waiver on the iPad. Doesn’t that mean I can’t sue?”
The answer, overwhelmingly, is no. In Texas, trampoline park waivers are vulnerable on multiple legal fronts. Our firm, led by Ralph Manginello and Lupe Peña, uses a specialized “Five Vector Attack” on every waiver we encounter:
Vector 1: The Minor Invalidation Rule (Munoz v. II Jaz, Inc.)
In Texas, the landmark case of Munoz v. II Jaz, Inc. (863 S.W.2d 207) established that a parent cannot pre-emptively sign away a minor child’s personal injury cause of action. Even if you signed the waiver for your eight-year-old, your child’s right to seek compensation for their injuries remains legally intact. The park’s insurance adjuster knows this, but they won’t tell you.
Vector 2: The Gross Negligence Carve-Out
No waiver in Texas can release a defendant from “gross negligence.” Under the Texas Civil Practice and Remedies Code § 41.001(11) and the Supreme Court’s ruling in Moriel, gross negligence involves an extreme degree of risk that the operator was subjectively aware of but consciously ignored. The $11.485 million Cosmic Jump verdict in Houston was possible only because the jury recognized that a torn mat combined with zero staff intervention is gross negligence.
Vector 3: The Fair Notice and Express Negligence Doctrines
Under Dresser Industries, Inc. v. Page Petroleum, a release of future negligence must be “conspicuous.” If the release language was buried in a long click-through screen, or if it didn’t specifically use the word “negligence” in a way that would attract a reasonable person’s attention, the waiver is void on its face.
Vector 4: The Signer Authority Defeat (Texas Family Code § 153.073)
We see this often at Carrollton birthday parties. A grandmother, an aunt, or a family friend takes the kids to the park and signs the waiver. Under Texas Family Code § 153.073, only a parent or a court-appointed conservator has the authority to sign for a child. A non-guardian signature is legally worthless.
Vector 5: Bilingual Formation Defect (Delfingen)
Texas is nearly 40% Hispanic. If your primary language is Spanish and the park presented you with an English-only iPad waiver under pressure to “just sign so the kids can jump,” you may not have formed a valid contract. The Delfingen US-Texas v. Valenzuela doctrine allows us to challenge waivers signed without a meaningful opportunity to understand the terms. Hablamos Español.

Catastrophic Injuries: What Carrollton Families Are Facing
A trampoline injury isn’t like a playground scrape. The biology and physics involved produce what we call “Nuclear Damages.”
Salter-Harris Growth Plate Fractures
In a developing child, the growth plates (physes) are made of cartilage, which is weaker than bone. A trampoline impact often causes a Salter-Harris Type II fracture. The disaster here is delayed manifestation: the leg may look “healed,” but by age 14, one leg is measurably shorter than the other because the growth plate stopped producing bone. We work with life-care planners to ensure your child’s settlement covers the medical monitoring and potential corrective surgeries they will need for the next decade.
Cervical Spine Injuries and SCIWORA
Pediatric necks are more mobile than adult necks. A child can suffer a spinal cord injury without a visible fracture on a CT scan—a condition known as SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). If your child was told they just had a “panic attack” after a backflip but they’re experiencing numbness or pain, like the young woman in the viral Elle Yona TikTok case, you need an immediate second opinion from a pediatric neurosurgeon.
Exertional Rhabdomyolysis
If your child jumped for 90 minutes in a hot indoor park and arrives at the ER with dark, cola-colored urine and severe muscle pain, they may have rhabdomyolysis. This is the breakdown of muscle tissue that releases myoglobin into the bloodstream, which can lead to acute kidney failure. We currently litigate a $10 million lawsuit against the University of Houston for similar pathology. We understand the myoglobin cascade, and we know how to hold the facility responsible for the dehydration and heat conditions that caused it.
The Evidence Clock: Why the Next 7 Days Are Critical
Evidence at a trampoline park near Carrollton has a shelf life. The defense team in these cases is not your friend. While they are calling you with a “friendly check-in,” their risk management team is managing the evidence.
- Surveillance DVRs: Most parks overwrite their security footage every 7 to 30 days. If we don’t send a formal spoliation letter within the first week, the video of the attendant on his phone during your child’s injury is gone forever.
- Incident Reports: We often find “initial” reports and “revised” reports. We use digital forensics to pull metadata and show when the park tried to change the narrative after the fact.
- Witnesses: The high turnover in this industry means the teenager who saw what happened will likely be working at a different job in 60 days. Our in-house investigators track these ex-employees down before they vanish.
- Wayback Machine Evidence: We use the Internet Archive to capture what the park’s safety claims were on their website the day of your injury, before they “update” them to hide their broken promises.
We don’t wait for discovery to begin. We send out a 10-section preservation demand within 24 hours of being retained. We demand the DVR hard drive, the foam-pit maintenance logs, and the franchisor’s audit reports.
Who Is Liable? Piercing the Corporate Shield
When we sue for a trampoline injury, we don’t just name the local LLC. We perform “Corporate Archeology” to reach the deep pockets.
- The Operator LLC: The entity that runs the specific Carrollton or Plano location.
- The Franchisee: The ownership group that may own multiple locations across Texas.
- The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC. In the Damion Collins case, the franchisor was held responsible for 40% of the $15.6 million award because they failed to implement safety changes across the chain.
- The Corporate parent: Sky Zone, Inc. or Unleashed Brands, often backed by multi-billion dollar private equity firms like Palladium Equity.
- The Manufacturer: For backyard cases, we target manufacturers like Jumpking, Skywalker, or Springfree. For parks, we target component manufacturers like Ropes Courses, Inc., the designer of the climbing wall in the Matthew Lu fatality.
A primary GL policy at a park is often only $1 million. That doesn’t cover a lifetime of ventilator care or a permanent TBI. We find the umbrella and excess layers that national chains use to protect their investors, and we make that money accessible to your child.
Why Hire Attorney911 for a Carrollton Trampoline Injury?
Most personal injury firms treat a trampoline case like a car wreck. They aren’t the same. To win against Sky Zone or Urban Air, you need a firm that has memorized ASTM F2970. You need a firm that knows exactly which clauses in a Texas waiver have been voided. You need Ralph Manginello’s 25 years of federal court experience and Lupe Peña’s insider knowledge of insurance defense.
As our client Chad Harris said, “You are NOT just some client… You are FAMILY to them.” We treat your child’s recovery fund as sacred. We advance every expense—the biomechanical engineer, the pediatric orthopedic consultant, the ASTM specialist—and you pay nothing unless we win.
If you are a parent in Carrollton or the DFW area, and your child’s life changed in one bad landing, the clock is running. The surveillance is being overwritten. The insurance adjusters are preparing their “assumption of risk” defense. Don’t let them push you around with a kiosk waiver.

Frequently Asked Questions for Carrollton Families
Can I really sue if I signed the waiver at the park?
Yes. As we discussed, Texas law under Munoz v. II Jaz says a parent cannot waive a minor’s right to sue. Furthermore, waivers never cover gross negligence. The largest trampoline park verdict in U.S. history—$11.485 million in Harris County—was against a park where a waiver had been signed. Our associate attorney Lupe Peña, who used to defend these parks, knows exactly where the holes are in their specific waiver language.
How long do I have to file a claim in Carrollton?
In Texas, the general statute of limitations for personal injury is two years (CPRC § 16.003). For children, this is “tolled” until they turn 18, meaning they technically have until their 20th birthday. However, you should never wait. The evidence clock is much shorter. Surveillance video at a Sky Zone or Urban Air is usually gone within 30 days. We recommend calling us within the first week so we can preserve the DVR and maintenance logs.
What if my child was double-bounced by an adult?
This is a classic violation of ASTM F2970 age and weight separation rules. The park has a non-delegable duty to keep vastly different sized jumpers apart. If an adult was allowed on the same bed as your child, the park is liable for the resulting fracture. The physics of double-bounce energy transfer is a “known hazard” the industry wrote standards to prevent.
My child’s urine is dark after visiting a trampoline park. Is this serious?
Yes. This is a medical emergency. Cola-colored or dark-brown urine is a sign of rhabdomyolysis, which can cause acute kidney failure. It happens when extreme jumping in heated indoor parks causes muscle tissue to rupture. Go to the ER immediately and ask for a CK (creatine kinase) test. After your child is stable, call us. We have active $10 million litigation involving this exact pathology.
Do I have to pay anything up front?
No. We work on a contingency fee basis. We advance all the costs of the experts—including the biomechanical engineers who reconstruct the double-bounce and the life-care planners who calculate your child’s future needs. You pay zero unless we successfully recover money for your family.
What if my child was hurt on a neighbor’s backyard trampoline in Carrollton?
Texas recognizes the “attractive nuisance” doctrine. A homeowner can be liable if they had a hazardous condition (like a trampoline) that they knew was likely to attract children who may not appreciate the risk. Even if your child was technically trespassing, the homeowner and their insurance could be held responsible. We also look at manufacturer defects from companies like Jumpking or Skywalker.
Urban Air told us they are a separate franchise LLC. Does that protect corporate?
No. We use the “apparent agency” doctrine. If the park looks like an Urban Air, uses their uniforms, their waivers, and their branding, the franchisor cannot hide behind a local LLC. The $15.6 million Damion Collins award proves that the big corporate entities can and will be held responsible for systemic safety failures.
Why didn’t the park call 911 for my child?
Unfortunately, some parks have a documented pattern of trying to downplay injuries. A review for the Southlake Urban Air noted that staff were instructed by management to NOT call 911. This is often a tactic to avoid attracting public attention to an injury. We treat the failure to call for emergency medical help as evidence of gross negligence.
How much is my child’s settlement worth?
It depends on the injury and the insurance layers. Pediatric catastrophic cases—like spinal cord injuries or TBIs—often reach the multi-million dollar range because of the 60-year lifespan of care required. Even “simple” fractures that damage a growth plate can settle in the $500,000 to $2 million range because of the long-term surgical risks. We use forensic economists to ensure you don’t settle for a fraction of what your child actually needs.
What should I do if the insurance adjuster calls me today?
Do not give a recorded statement. They will be looking for any reason to blame your child or you. Simply tell them, “I am represented by Attorney911, and my attorney will be in touch.” Then hang up and call us.
What happened to your child wasn’t just bad luck. It was the predictable output of a system designed to maximize jumpers per hour while minimizing cost per attendant. The American Academy of Pediatrics warned them. The ASTM standards told them exactly how to operate. The corporate parents chose a different path.
Attorney911 was built for exactly this fight. Ralph Manginello brings federal court experience and a 25-year record against Fortune 500 defendants. Lupe Peña brings the insider knowledge that defeats waivers. Our DFW-adjacent offices mean we are local to the chains and local to your family.
