The Mother’s Day that Stopped: Navigating Trampoline Injuries in North Richland Hills
One bounce. One bad landing. One broken neck. That is all it takes at an indoor trampoline park.
Imagine it is a Saturday afternoon in North Richland Hills. You are at a birthday party at a facility like the Urban Air in neighboring Bedford or the Ninja Kidz right here in our community. The court is packed with children. The low-frequency thud of hitting the mat is constant, mixed with the high-pitched music and the smell of concession-stand pizza. You are watching your seven-year-old daughter. You signed the waiver at the kiosk twenty minutes earlier because the line was long and the staff was pressuring everyone to hurry so the party could stay on schedule.
Then, the double-bounce happens. A teenager, nearly twice your daughter’s weight, lands on the same trampoline bed just as she is pushing off. The energy transfer multiplies her launch force by up to four times. She is not jumping anymore; she has become a projectile.
As she descends, her knees buckle. She lets out a sound that every parent fears—what Texas mother Kati Hill called, in an interview with ABC News, “the worst scream that you could ever have heard from a child.” Before the paramedics from the North Richland Hills Fire Department even arrive, the park’s risk-management team is already working. They are not working to help your daughter. They are working to protect the park’s margin. They have a system for denying claims. We have a system for winning them.
If your family is standing at the bedside at Cook Children’s Medical Center or Children’s Medical Center Dallas right now, you need more than just “a lawyer.” You need an advocate who understands that what happened to your child was not an accident—it was the predictable output of a business decision. At The Manginello Law Firm, also known as Attorney911, we have spent over 25 years making corporate defendants accountable for the decisions they make at the expense of families.
Since 1998, Ralph Manginello has gone head-to-head with Fortune 500 giants like BP, Walmart, and Amazon. Our associate attorney, Lupe Peña, brings a unique edge to your case: he used to sit on the other side of the table, defending insurance companies and recreational businesses against these exact claims. He knows which waiver clauses are airtight and which ones are full of holes. Together, we handle trampoline injury cases in North Richland Hills and throughout the state of Texas with a level of technical mastery generic personal injury firms cannot match.
The clock is already running. Park surveillance video is often overwritten in as little as seven to thirty days. If you wait, the evidence of the understaffed court and the distracted monitor disappears. Call us today at 1-888-ATTY-911. Hablamos Español. No fee unless we win.
The Industry Standard the Park Ignored: ASTM F2970
Most personal injury firms can’t tell you what ASTM F2970 requires of a trampoline park. We can cite it from memory. ASTM F2970 is the standard for the design, manufacture, installation, and operation of commercial trampoline courts. It wasn’t written by the government; it was written by the trampoline park industry itself to establish a safety floor. When a park in North Richland Hills violates F2970, it is violating the very rules its peers agreed upon.
Section 10 of ASTM F2970 provides specific guidance on attendant-to-jumper ratios. On a busy weekend in North Richland Hills, these ratios are often the first thing to slip. When one “court monitor” is responsible for watching sixty children, they are not supervising—they are merely watching a disaster develop.
Furthermore, we pair every mention of U.S. voluntary standards with EN ISO 23659:2022. This is the international and mandatory European standard for trampoline parks. It requires specific foam pit depths and airbag specifications that the U.S. industry treats as optional. Sky Zone, Urban Air, and DEFY operate to a floor that the rest of the developed world treats as a ceiling. When we depose a park’s operations manager, we know their standards better than they do.
Why Your Signed Waiver is Not a Wall
The trampoline park’s insurance adjuster will call you within 48 hours. She will sound concerned. She will mention the waiver you signed as if it ends your case. It doesn’t. In Texas, a signed waiver is a speed bump, not a brick wall.
First, under the Texas “fair notice” doctrine established in Dresser Industries v. Page Petroleum, a waiver must be conspicuous and use the express word “negligence” to be enforceable. Many electronic kiosk waivers are buried in twenty screens of click-through text that a reasonable person in a crowded North Richland Hills lobby would never fully digest.
Second, and most importantly for parents, is the doctrine found in Munoz v. II Jaz Inc. In Texas, a parent cannot bind a minor child to a pre-injury waiver of the child’s own personal injury claim. While the parent’s own claims for medical bills might be affected, the child’s independent right to recovery survives.
Third, no waiver in Texas can release a defendant from “gross negligence.” Under Texas Civil Practice and Remedies Code § 41.001(11), gross negligence is defined as an act or omission that involves an extreme degree of risk, of which the defendant had actual awareness but proceeded with conscious indifference.
Consider the case of Max Menchaca. In a Harris County courtroom, a jury awarded $11.485 million against the operator of Cosmic Jump after a sixteen-year-old fell through a torn trampoline slide onto concrete. The park had actual knowledge of the tear and did nothing. Even though a waiver was signed, the jury found gross negligence. That is exactly the type of case we are built to handle. We don’t just look for “accidents”; we look for the conscious decisions that lead to catastrophe.
The 5-Layer Stack: Who We Actually Sue
When we say we are suing a park like Urban Air or Sky Zone, we are not just suing the building down the street. We perform a full corporate archeology on every case to find the money that is intentionally shielded by layers of LLCs.
- The Operator LLC: The local entity in North Richland Hills that owns the equipment and employs the staff.
- The Franchisee: Often a larger multi-unit holding company that owns several locations across DFW.
- The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC. They dictate the training manuals and audit the safety practices.
- The Parent Company: Sky Zone, Inc. (formerly CircusTrix) or Unleashed Brands. These are often backed by massive private equity firms like Palladium Equity Partners or Seidler Equity Partners.
- The Private Equity Sponsor: The ultimate money. They approved the cost-cutting measures that reduced the number of attendants on the floor the day your child was hurt.
We currently litigate a $10 million lawsuit against a major university involving rhabdomyolysis and acute kidney failure. That case has thirteen separate defendants. We know how to document institutional accountability, how to pierce corporate shells, and how to make the parent conglomerates pay.
Understanding the Medicine: Why Pediatric Injuries are Different
A “broken leg” at a trampoline park in North Richland Hills is rarely just a broken leg. Pediatric bone is biomechanically distinct. Children have an open physis, or growth plate. A Salter-Harris Type II fracture at age eight can destroy the cells responsible for bone growth. Your daughter might not show a limb-length discrepancy today, but at age fourteen, one leg may be measurably shorter than the other because that growth plate was crushed years ago.
We also focus on under-recognized mechanisms like extended-jumping rhabdomyolysis. If your child jumped for ninety minutes in a heated indoor park and arrives at the ER two days later with dark, cola-colored urine, they are in a medical emergency. Myoglobin from ruptured muscle cells is clogging their renal tubules, leading to acute kidney failure. This is the same physiology we are litigating in our $10 million University of Houston case. Most attorneys miss this diagnosis. We look for it.
For families in North Richland Hills, we also watch for “spinal-cord stroke” or vertebral artery dissection. The viral TikTok case of Elle Yona, which has over 27 million views, showed a teenager who sustained a stroke after a backflip. It was initially misdiagnosed as a panic attack. In children and teens, the cervical spine is so pliable that the artery can be sheared without a bone ever breaking. This produces SCIWORA—Spinal Cord Injury Without Radiographic Abnormality.
The Evidence Clock: What Happens in the Next 7 Days
In North Richland Hills, the legal statute of limitations for personal injury is two years. But the evidence clock is measured in days.
- Surveillance Overwrite: Digital Video Recorders (DVRs) used by major chains are often set to overwrite in 7 to 30 days. Without a legal spoliation letter, the foot-speed and monitor-inattention evidence is gone forever.
- Waiver Purges: The kiosk databases often purge version histories on a 72-hour rolling cycle.
- Incident Report Revisions: We have seen facilities “update” or “sanitize” incident reports days after the injury occurs. Metadata forensics can find the original version, but only if we act quickly.
We send our spoliation letters by certified mail within 24 hours of being retained. We demand the DVR hard drive, the training logs of the teenagers on duty, and the daily inspection records of the foam pit or trampoline beds. We don’t wait for the insurance company to “check in.” We move into the discovery phase while the trail is still warm.

Frequently Asked Questions for North Richland Hills Parents
Can I sue if I signed the trampoline park waiver at the Urban Air or Ninja Kidz in North Richland Hills?
Yes. Texas law has very specific requirements for waivers under the Dresser doctrine. They must be “express” and “conspicuous.” Furthermore, because of the Munoz case, a parent cannot waive a child’s right to sue for their own injuries in a commercial setting. If the park was grossly negligent—for example, if they knew a trampoline bed was torn but didn’t fix it—the waiver does not apply at all.
How much is my child’s trampoline injury case worth?
Every case is different, but catastrophic trampoline injuries frequently settle in the multi-million dollar range. A Salter-Harris growth plate fracture often anchors in the $500,000 to $2 million range because of the need for a decade of medical monitoring. Cases involving permanent spinal cord injuries or traumatic brain injuries can reach $15 million or more, such as the $15.6 million award in the Collins v. Urban Air arbitration.
What should I do if my child has dark urine after jumping?
Go to the emergency room immediately and ask for a creatine kinase (CK) blood test and a urinalysis for myoglobin. This is a sign of exertional rhabdomyolysis, which can lead to rapid kidney failure. This condition often appears 24 to 48 hours after the jump session. Save your receipts from the concessions to prove hydration was not prioritized by the park staff.
The park manager said they aren’t liable because my child “didn’t follow the rules.” Is that true?
No. In Texas, children under the age of seven are generally presumed incapable of negligence. For children between seven and fourteen, the park must prove the child had the maturity to understand the specific risk. More importantly, the park has a “non-delegable duty” to supervise. They cannot blame a child for a double-bounce that their own monitor should have prevented by enforcing age and weight separation rules.
How do I get the video footage of the accident?
You likely cannot get it on your own. Most parks will refuse to show it to you or give you a copy. We obtain this footage by sending a formal legal notice within twenty-four hours of retention. If they destroy the video after receiving our notice, the court can issue a “spoliation instruction,” which tells the jury to assume the video was bad for the park.
My child’s injury happened on a neighbor’s backyard trampoline in North Richland Hills. Who is responsible?
This falls under the “attractive nuisance” doctrine. A homeowner has a duty to secure a trampoline from neighborhood children who might be attracted to it. Even if the child was a guest, the homeowner’s insurance policy often provides coverage. However, many standard policies in North Richland Hills exclude trampolines. We look for every layer of coverage, including umbrella policies and potential product liability claims against manufacturers like Springfree or ACON.
What if the waiver was only in English and we speak Spanish?
Under the Delfingen doctrine in Texas, a waiver signed by someone who cannot read the language it is written in may be held unenforceable for lack of meaningful assent. Our firm and attorney Lupe Peña speak Spanish fluently. We prioritize ensuring our Spanish-speaking families are not taken advantage of by English-only kiosk agreements.
Does it cost anything to hire your firm?
No. We work on a contingency fee basis. This means we only get paid if we recover money for you. We take the financial risk so that you can focus on your child’s recovery. We pay the upfront costs for the high-level experts that these complex corporate liability cases require.
How do you prove the park was understaffed?
We subpoena the time-clock records and the daily shift schedule for the day your child was hurt. We then cross-reference that with the number of jumpers on the floor. If the ratio exceeded the ASTM F2970 industry standard of approximately 1:32, we have direct evidence of negligent staffing.
Why is rhabdomyolysis a risk at trampoline parks?
The indoor environment at these facilities is often poorly ventilated and hot. Extended jumping is a form of extreme eccentric muscle loading. Combined with the sugary drinks sold at concessions and the lack of mandatory water breaks, children can easily become dehydrated. This causes muscle tissue to “melt” into the bloodstream, a process called rhabdomyolysis.
Can I sue the corporate headquarters even if the park in North Richland Hills is a franchise?
Yes. Under the theory of “apparent agency” and “retained control,” we pursue franchisors like Urban Air or Sky Zone. They control the brand, the training, and the policies. The award of $15.6 million to Damion Collins saw the franchisor, UATP Management, take 40% of the fault despite not owning the local building.
What if my child’s injury seems “minor” now?
Fractures in children can hide long-term damage. A tibial fracture that seems to have healed might result in a leg that ceases to grow. Concussions can lead to academic decline that doesn’t manifest until the next semester. We never settle a case until we have a full medical prognosis from top-tier pediatric specialists.
Is the foam pit really dangerous?
Yes. The industry is actively replacing foam pits with airbags because the foam blocks compact over time, losing their ability to absorb impact. A “full” looking foam pit might only have four inches of effective cushion at the bottom. Head-first entries into foam pits are the leading cause of trampoline-related quadriplegia in the United States.
How long does a trampoline injury lawsuit take?
Simple cases can resolve in six to twelve months. Catastrophic cases involving multiple corporate defendants and extensive medical documentation can take two to three years. We prepare every case for trial from day one, which often forces the insurance company to settle sooner rather than later.
What if my child’s teacher or a camp counselor signed the waiver?
A non-guardian signature is rarely binding on a child’s rights in Texas. Tex. Fam. Code § 153.073 says only a legal guardian holds that authority. If a school field trip resulted in an injury, the waiver the school signed may be a legal nullity as to your child’s claim.
Your Next Steps: Accountability Starts Now
What happened to your child at a North Richland Hills trampoline park wasn’t just bad luck. It was the predictable output of a system designed to maximize jumper density while minimizing labor costs. The American Academy of Pediatrics has been warning about these hazards since 1999. ASTM F2970 was drafted by the industry itself to establish a safety floor, and the park operated below that floor.
Attorney911 was built for exactly this fight. Ralph Manginello brings 25+ years of catastrophic injury experience to the table. Lupe Peña knows exactly which waiver clauses the insurance companies will cite because he used to write them. Our active $10 million University of Houston rhabdomyolysis case uses the same medical experts and institutional-accountability framework we will apply to your child’s injury.
Your child’s case is decided by what gets preserved this week. Surveillance DVRs overwrite, foam pits get refilled, and witnesses move away. Call 1-888-ATTY-911 today. Hablamos Español. No fee unless we win. We will advance every expense to ensure your child has the recovery fund they deserve.
