“One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park.”
At the Altitude Trampoline Park on Belt Line Road in Cedar Hill, or any of the dozens of facilities across the DFW metroplex, a Saturday afternoon birthday party can turn into a life-altering medical emergency in less than two seconds. You see your child airborne, and then you hear it. Kaitlin “Kati” Hill described it to ABC News as “the worst scream that you could ever have heard from a child” when her three-year-old son Colton’s femur snapped during a “Toddler Time” session. Like so many families in Cedar Hill, she was told the facility was safe. She signed the waiver at the kiosk. She believed the marketing. And then, at the trauma-bay bedside, she realized the truth.
“We had no idea,” she said.
At Attorney911, we believe that no parent in Cedar Hill should have to say those words. We are The Manginello Law Firm, a catastrophic injury practice with twenty-five years of experience holding multinational corporations accountable. From our offices in Houston, Austin, and Beaumont, we represent families across Texas and nationwide who have been devastated by an industry that scales known risks to industrial levels while operating in a regulatory vacuum.
If your child was injured at a trampoline park in Cedar Hill or sustained a catastrophic injury on a backyard trampoline, you are likely being told that you “assumed the risk” or that the waiver you signed ends your case. We are here to tell you that the waiver is not the wall the park wants you to believe it is.
What happened to your child wasn’t a “freak accident.” It was the predictable output of a business decision made to protect profit margins at the expense of safety. At Attorney911, led by Ralph Manginello and former insurance defense attorney Lupe Peña, we have built a practice designed specifically to dismantle the trampoline industry’s liability shields. We don’t just “handle” these cases; we architect the evidence to prove that the park knew the injury would happen and chose not to stop it.
Call us today at 1-888-ATTY-911. We answer 24/7. Hablamos Español. We work on a contingency basis—no fee unless we win—and we advance every cost required to win, from biomechanical engineers to pediatric orthopedic specialists. Your child’s recovery fund stays intact while we fight.
Why Trampoline Injuries Are Rising in Cedar Hill
Cedar Hill families have lived through the explosion of the indoor adventure park industry. What started in 2004 with the founding of Sky Zone has turned into a multi-billion dollar sector dominated by private equity firms like Palladium Equity Partners (parent of Sky Zone, DEFY, and Rockin’ Jump) and Seidler Equity Partners (parent of Urban Air).
The data confirms the danger. Approximately 1.6% of all pediatric emergency department trauma visits in the United States are now related to trampolines, according to a 2024 study published in the American Journal of Roentgenology. In January 2024, the journal Pediatrics published a landmark study by Teague et al. documenting 13,256 injuries from 8.4 million jumper-hours. The study revealed a foam-pit injury rate of 1.91 per 1,000 jumper-hours and a high-performance jumping injury rate of 2.11 per 1,000.
In a metro area with the park density of DFW—home to over 30 facilities including Urban Air HQs in Grapevine and Altitude HQs in Fort Worth—the number of injured children is measured in the thousands. A Fort Worth Star-Telegram investigation uncovered 500 injury reports at 21 regional trampoline parks over a seven-year span. These aren’t just statistics; these are Cedar Hill children arriving at Level 1 pediatric trauma centers like Children’s Medical Center Dallas or Cook Children’s in Fort Worth with comminuted fractures, traumatic brain injuries (TBI), and permanent spinal cord damage.
The Regulatory Vacuum and the Industry’s “Safety” Standards
One of the most persistent myths in Cedar Hill is that someone is inspecting these parks for safety. The truth is that there is no federal agency with direct jurisdiction over commercial trampoline park facilities.
In Texas, the regulatory gap is even wider. While the Texas Department of Insurance (TDI) regulates “Class B” inflatable amusement rides (like bungee trampolines or Sky Rider zip-coasters) under Texas Occupations Code Chapter 2151, the core trampoline decks are statutorily excluded under Section 2151.002(1)(C)(iv). This means the state verifies the insurance and inspection stickers for the inflatables inside an Urban Air, but leaves the most dangerous part of the park—the trampoline courts—entirely self-regulated.
The industry “standard” is ASTM F2970. It is a voluntary standard written by the trampoline industry itself. While it establishes requirements for attendant-to-jumper ratios, age separation, and foam pit maintenance, the only entity checking for compliance on a Saturday afternoon in Cedar Hill is the park’s own management.
At Attorney911, we pair the voluntary nature of ASTM F2970 with international standards like EN ISO 23659:2022, which is the mandatory standard across Europe. We use this comparison to prove that Sky Zone, Urban Air, and DEFY are operating at a safety floor that the rest of the developed world treats as a dangerous ceiling. When we depose a park manager, we don’t ask if they are “safe.” We ask why they chose to violate specific ASTM F2970 provisions—like the requirement to separate jumpers by age and weight—knowing that failing to do so makes a child 14 times more likely to suffer a catastrophic injury.
The Physics of Failure: Why Cedar Hill Kids Get Hurt
Most trampoline injuries happen because of the physics of rebound energy. When a 200-pound adult lands on a trampoline bed at the same time a 60-pound child is pushing off, kinetic energy transfers through the mat. This “double-bounce” can multiply the child’s launch force by up to four times. The child isn’t jumping anymore; they are being catapulted.
The injuries we see most often in Cedar Hill include:
1. Pediatric Femur and Tibia Fractures
These are often “trampoline fractures”—proximal tibial metaphyseal buckle fractures—specific to children aged two to five. In older children, we see comminuted femoral shaft fractures requiring ORIF (open reduction internal fixation) surgery.
2. Salter-Harris (Growth Plate) Injuries
This is the silent catastrophe. A fracture through the growth plate at age eight may not show its true damage until age 14, when the child’s leg stops growing correctly or grows crooked. Most personal injury firms settle these cases based on the ER bill. At Attorney911, we monitor these cases through skeletal maturity because we know a Salter-Harris injury is a decade-long medical journey.
3. SCIWORA and Cervical Injuries
Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) is a pediatric phenomenon where the cord is damaged even if the bones look normal on a CT scan. A head-first landing into an unmaintained foam pit can produce cord ischemia or even a vertebral artery dissection—a “spinal-cord stroke.”
We watched the Elle Yona case go viral on TikTok in June 2024, reaching 27 million views. She was a teen who attempted a backflip into a foam pit, suffered sudden back pain, and was initially misdiagnosed with a “panic attack” before being diagnosed with C4 incomplete quadriplegia. We know how to document this neurovascular pathology and hold the park accountable for failing to prevent these high-risk maneuvers.
4. Exertional Rhabdomyolysis
If a child jumps for 90 minutes in a hot indoor facility like those in Cedar Hill during a 100-degree Texas summer, they can develop rhabdomyolysis—the breakdown of muscle tissue that poisons the kidneys. If your child has “cola-colored” urine, listlessness, or extreme muscle pain 24 hours after a park visit, go to the emergency room immediately.
Our firm’s experience is unique here. We currently litigate a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. We have already built the medical expert team and the discovery architecture to prove the link between institutional negligence and this catastrophic muscle breakdown.
Who is Responsible for Your Child’s Injury?
When we investigate a park injury in Cedar Hill, we don’t just sue the local LLC. We perform a “corporate structure archeology” to find the money hidden upstream. The typical defendant stack includes:
- The Operator LLC: The local entity running the Cedar Hill facility.
- The Franchisee: A multi-unit ownership group that often understaffs to hit performance targets.
- The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC (Urban Air) that mandate the standards but fail to enforce them.
- The Corporate Parent: Sky Zone, Inc. or Unleashed Brands, often backed by private equity sponsors like Palladium or Seidler.
- The Manufacturer: If a mat tore, a net failed, or a harness didn’t lock, we name the equipment vendor (like Ropes Courses, Inc. or UA Attractions LLC).
In one landmark Kansas case, Damion Collins v. Urban Air Overland Park, an arbitrator awarded $15.6 million for quadriplegia. The franchisor, UATP Management LLC, was held responsible for 40% of the debt because of its “systemic failure” to implement safety changes. This is the blueprint we use: go upstream, find the deep pockets, and prove that the corporate parent controlled the decisions that led to the injury.
Dismantling the “Signed Waiver” Defense in Texas
The park’s first move will be to point at the screen you tapped when you walked in. In Texas, waivers are enforceable for ordinary negligence, but only if they meet the fair-notice doctrine established in Dresser Industries v. Page Petroleum. This requires “express negligence” (using the specific word “negligence”) and “conspicuousness” (text that a reasonable person would notice).
But there are three primary ways we defeat these waivers in Cedar Hill courts:
1. Gross Negligence Carve-Out
No waiver in Texas can release a company from liability for its own gross negligence. Under the Moriel standard, if the park had “subjective awareness” of an extreme risk and acted with “conscious indifference,” the waiver is worthless. The Cosmic Jump $11.485 million verdict in Houston proved this: the jury found the park grossly negligent for letting a teen jump on a torn trampoline they knew was broken.
2. Minor Rights and Munoz v. II Jaz
Since 1993, Texas law has been clear: a parent cannot sign away a minor child’s personal cause of action. While the parent’s claim for medical bills might be barred, the child’s own claim for pain, suffering, impairment, and future medical costs survives.
3. The Delfingen Bilingual-Formation Defeat
If your primary language is Spanish and you were presented with an English-only iPad waiver at a rushed front counter, you did not form a valid contract. Attorney Lupe Peña applies the Delfingen doctrine to prove that the “agreement” was procedurally unconscionable.
We also watch the 2025 jurisdictional split closely. While the Texas Supreme Court in Cerna v. Pearland Urban Air recently enforced a delegation clause in an arbitration agreement, our team knows exactly which arguments still keep your case in a local courtroom—and how to win even if we are moved to arbitration.
The Evidence Clock: Why You Must Call Today
The transition from a “bad landing” to a “successful lawsuit” depends on what is preserved in the first seven days. Trampoline park evidence is engineered to disappear:
- Surveillance DVRs typically overwrite every 7 to 30 days.
- Incident reports are often “finalized” (revised by corporate risk teams) 48 hours after the event.
- Waiver databases can purge specific version metadata on rolling cycles.
- Foam pits get refilled, hiding the compaction that caused the injury.
- Attendants transfer or quit, and most parks have a 130-150% annual turnover rate.
One family at a park in Southlake, Texas, reported on Tripadvisor that “employees are specifically instructed by management to NOT call 911.” This is a tactic used to buy time so the evidence fades.
When you retain Attorney911, our spoliation letter goes out within 24 hours. We use forensic tools like Cellebrite and EnCase to acquisition digital data, and we subpoena the original, unrevised incident reports using metadata edit-trails. We identify the ex-employees through LinkedIn alumni searches before the park’s lawyer can shield them. We find the person who was on their phone while your child was falling.
Building Your Multi-Million Dollar Case
We don’t handle these like slip-and-falls. We build a medical and vocational architecture to support a full life-care plan. A catastrophic injury at age nine means seventy years of medical exposure. We calculate:
- Future Surgeries: Hardware removal, corrective osteotomies, or spinal revisions.
- Lost Earning Capacity: Using forensic economists to project what your child would have earned over an adult career.
- Educational Costs: IEP coordination, tutoring, and special education needs for TBI victims.
- OPSI Risk: If your child lost their spleen, they face a lifetime risk of “overwhelming post-splenectomy infection” which requires a distinct damages model most firms miss.
We’ve gone toe-to-toe with Fortune 500 companies like BP, Walmart, and FedEx. The private equity sponsors behind Sky Zone and Urban Air don’t bring anything we haven’t seen before.
Backyard Trampoline Dangers in Cedar Hill Suburbs
In suburban Cedar Hill neighborhoods, the backyard trampoline is the primary hazard. Manufacturers like Jumpking, Skywalker, and Bouncepro (sold at Walmart) have massive recall histories. In 2005, Jumpking recalled one million trampolines for breaking frame welds. In 2026, the CPSC announced a recall of SEGMART toddler trampolines for strangulation hazards.
If your child was hurt on a neighbor’s trampoline, Texas law applies the Attractive Nuisance doctrine. A homeowner who has an accessible, dangerous trampoline can be liable for injuries to trespassing children who are too young to appreciate the risk. We know how to navigate homeowners’ insurance exclusions to find the coverage you need.
Frequently Asked Questions
Can I sue if I signed the waiver at an Urban Air or Sky Zone near Cedar Hill?
Yes. In Texas, waivers don’t cover gross negligence, and parental waivers rarely bar a minor child’s own claim. We run every waiver through a five-vector attack to find the seams corporate counsel tried to hide.
How much does a trampoline park lawyer cost?
At Attorney911, it costs nothing upfront. We work on a contingency fee. We pay for the biomechanical engineers and the pediatric neurosurgeons. You pay us a percentage of the recovery only if we win.
The park manager offered to pay our medical copay if we sign a release. Should I?
No. This is the “Med-Pay Trojan Horse.” By accepting a $3,000 check for an ER visit, you may be signing away a $3 million claim for a permanent growth plate injury. Never sign anything from an insurance adjuster without us reading it first.
How long do I have to file a lawsuit in Texas?
For an adult, it is two years. For a child, the statute is generally “tolled” until they turn 18, giving them until age 20. However, wait a month and the video footage is gone. Wait a year and the witness is gone. The evidence clock is your real deadline.
Will my case go to arbitration?
It might, but arbitration is not the end. The Damion Collins $15.6 million award happened in arbitration. We are trial lawyers. If we have to go to arbitration, we treat it with the same aggressive discovery and expert-witness depth we bring to a courtroom.
