At the Sky Zone in City of Richland Hills, or perhaps just across the city line in North Richland Hills or Hurst, a seven-year-old comes off a court on a stretcher. His parents had signed the waiver at the kiosk twenty minutes earlier. They were told it was just a formality. They were told the rules made the park safe. Then, in the blur of a Saturday afternoon near Loop 820, a double-bounce occurred on a crowded court, and the physics of the industry’s own design took over.
“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. Her warning post was shared 240,000 times. We read it. So did every parent of every child who has been hurt at a trampoline park in Tarrant County since. We represent families who have lived that nightmare. We represent children who are facing a decade of orthopedic monitoring because a business decided to staff its courts at sixty percent of the required safety ratio to protect a profit margin.
We are Attorney911. Our managing partner, Ralph Manginello, has represented catastrophic injury victims since 1998, bringing over 25 years of courtroom experience to every case we file. We have gone toe-to-toe with Fortune 500 corporations like BP, Walmart, and Amazon, and we have made them pay. The parent conglomerates behind national trampoline park chains — Sky Zone, Inc. (formerly CircusTrix LLC), backed by Palladium Equity Partners; and Unleashed Brands, the parent of Urban Air, backed by Seidler Equity Partners — do not bring lawyers more intimidating than the ones we have already beaten.
If your child was injured in City of Richland Hills, the clock is already running. Park surveillance DVRs typically overwrite in as little as 7 to 30 days. The incident report you filled out is being “finalized” (revised) by management. The waiver you signed may be purged from the kiosk database on a 72-hour rolling cycle. Our spoliation letter goes out within 24 hours of your retention — certified mail to the park, the franchisor, and the insurer. We don’t wait for them to “get back to us.” We freeze the evidence.
Call 1-888-ATTY-911. Hablamos Español. Our team includes Lupe Peña, an attorney who used to sit on the other side of the table defending recreational businesses against these exact claims. Now he uses that playbook against them. He knows which waivers are airtight and which ones are full of holes under Texas law.
The Systemic Architecture of Negligence in City of Richland Hills
Trampoline injuries are never pure accidents. They are the predictable output of a systemic architecture designed to maximize throughput and minimize liability. In a metro as dense with family entertainment as City of Richland Hills and the surrounding Northeast Tarrant corridor, the pressure on these parks to maintain margins is immense.
The industry knows the risks. They wrote the standard themselves. ASTM F2970 is the safety floor for commercial trampoline courts. It requires specific attendant-to-jumper ratios, age-separated jumping zones, and foam-pit depth requirements. But walk into any park near the Airport Freeway on a Saturday, and you will see those standards collapsing under the weight of birthday parties and “Glow Night” crowds.
When a 200-pound adult lands on a bed while a 60-pound child is pushing off, the energy transfer multiplies the child’s launch force by up to 4x. This is not an “inherent risk.” This is a violation of the age-separation provisions of ASTM F2970. The park collected your money and accepted the duty to keep those weight classes separate. When they failed, they breached the standard of care.
Ralph Manginello and our firm have recovered multi-million dollar settlements for traumatic brain injury and spinal cord injury victims — the same catastrophic categories a trampoline park can cause in a single bad landing. Most personal injury firms handle a trampoline case like a slip-and-fall. We don’t. We treat it like the complex corporate-accountability case it actually is.

Why the Waiver You Signed in Tarrant County Is Not a Wall
The park’s insurance adjuster will call you within 48 hours. She will be friendly. She will ask how your child is doing. Then she will mention the waiver you signed at the kiosk as if it ends your case. She is counting on you not knowing Texas law.
In City of Richland Hills, your rights are governed by specific Texas doctrines that we have spent over two decades mastering. That piece of paper is not an automatic shield.
First, under the landmark Texas ruling in Munoz v. II Jaz Inc. (1993), a parent generally cannot sign away a minor child’s personal-injury cause of action in advance. Your signature may bar your own derivative claims for medical bills, but it does not bar your child’s right to recover for their own pain, suffering, and permanent impairment.
Second, Texas courts refuse to enforce waivers where the injury resulted from gross negligence. Under the Moriel standard, gross negligence means the park had subjective awareness of an extreme risk and proceeded with conscious indifference anyway. In Harris County, a jury awarded $11.485 million against the operator of Cosmic Jump after a teen fell through a torn trampoline mat onto concrete. The jury found the park knew the mat was torn and did nothing. That is exactly the kind of case we are built to handle.
Third, the Dresser fair-notice doctrine in Texas requires the release to be conspicuous. If the negligence release was buried in a 20-screen iPad click-through with dozens of other paragraphs, it may be void on its face. We also deploy the Delfingen doctrine for our Spanish-speaking families; if the waiver was English-only and you were not provided a translation or a meaningful opportunity to understand it, the contract itself may have failed to form.
Our associate attorney Lupe Peña speaks with you directly in Spanish — no interpreters, no delays. Si su idioma principal es el español, el caso de Delfingen US-Texas v. Valenzuela puede invalidar la renuncia que usted firmó. Llame al 1-888-ATTY-911.
The Hidden Danger of Adjacent Attractions
Modern parks in the City of Richland Hills area, like Urban Air or the nearby Ninja Kidz in North Richland Hills, are no longer just trampolines. They are family entertainment centers (FECs) with Sky Rider indoor coasters, climbing walls, ropes courses, and go-karts.
These adjacent attractions carry their own deadly failure modes. We have seen the patterns across the country. In 2019, 12-year-old Matthew Lu died at an Altitude park after employees failed to properly secure his harness, resulting in a 20-foot fall onto concrete. In 2025, a six-year-old named Emma Riddle died at an Urban Air during a go-kart malfunction.
When a park bolts on a high-speed mechanical ride or a 30-foot climbing wall, they are no longer just a jump park. They are an amusement park operating without state oversight. In Texas, the Department of Insurance regulates “Class B” inflatable rides, but the trampoline decks are statutorily excluded. This regulatory gap is a foreseeability argument we use in court. The park knew the state wasn’t watching, so they had a heightened duty to watch themselves. They didn’t.
We advance every expense for your case — the expert biomechanist, the pediatric orthopedic consultant, the ASTM compliance specialist. You pay nothing unless we win. 888-ATTY-911.
Pediatric Injuries: The Long-Term Cost for City of Richland Hills Families
A “broken leg” at age eight is never just a broken leg. If the fracture line extends through the growth plate (the physis), it is a Salter-Harris fracture. This is an orthopedic catastrophe. The bone that should have produced healthy growth for the next ten years may now grow crooked, grow short, or stop growing entirely.
Your child may require corrective osteotomy or epiphysiodesis (surgically stopping growth on the healthy leg to equalize length) years after the insurance company tried to settle your case for a few thousand dollars. We don’t settle for the ER bill. We build a Pediatric Life-Care Plan that forecasts your child’s medical needs through skeletal maturity and beyond.
We also bridge the medicine to our active litigation. We are currently litigating a $10 million lawsuit against a major university involving rhabdomyolysis and acute kidney failure — the same catastrophic muscle breakdown we see in children who jump for ninety minutes in a hot indoor park without hydration. We know the biochemistry, we know the experts, and we know how to hold institutional defendants accountable.

Frequently Asked Questions for City of Richland Hills Parents
Can I sue if I signed the waiver at a Sky Zone or Urban Air in City of Richland Hills?
Yes. Despite what the front-desk attendant said, the waiver is not an absolute shield. In Texas, a parent cannot waive a minor’s personal cause of action under Munoz v. II Jaz. Furthermore, no waiver covers gross negligence — such as ignoring ASTM F2970 attendant ratios during peak hours. If the park knew of a hazard (like a torn mat or understaffing) and did nothing, the waiver fails.
How long do I have to take action in Tarrant County?
The Texas statute of limitations is two years from the date of injury. For a minor, the clock is tolled until they turn 18, meaning they technically have until their 20th birthday. However, you should never wait. Surveillance video at local parks is often overwritten within 7 to 30 days. Witnesses transfer to new jobs. The incident report gets “re-drafted.” Call 1-888-ATTY-911 this week.
What is a “double bounce” and why is it so dangerous for my child?
A double-bounce occurs when a heavier jumper lands while a lighter jumper is pushing off. The energy transfer can multiply the child’s launch force by up to 4x. Because children’s bones are more pliable and their growth plates are still cartilage, this force routinely causes “trampoline fractures” of the proximal tibia. ASTM F2970 requires parks to separate age and weight classes specifically to prevent this.
The park’s insurance company offered to pay our medical bills. Should I take it?
No. This is likely a “Med-Pay” offer, often around $3,000 to $5,000. It is a Trojan horse. Accepting that check usually requires you to sign a full release, effectively ending your claim for six- or seven-figure damages like permanent growth-plate impairment or TBI. Consult with Ralph Manginello before you sign anything.
What if the park says they aren’t responsible because they are a franchise?
This is a standard corporate shield. We pierce it using the apparent agency doctrine. When a park uses the franchisor’s colors, logos, training manuals, and rules, they are signaling to the public that there is one standard of safety. In the $15.6 million Damion Collins award, the franchisor (UATP Management LLC) was held responsible for 40% of the fault. We look at every layer: the operator, the franchisee, the franchisor, and the corporate parent Sky Zone, Inc. or Unleashed Brands.
Is the foam pit really safe for my toddler?
By the industry’s own actions, the answer is no. Major chains have been replacing foam pits with airbags for years because foam blocks compact over time, losing their ability to absorb impact. Head-first entries into foam pits have caused permanent quadriplegia across the country. If the park in City of Richland Hills still uses a foam pit, they are making a cost-saving choice with your child’s safety.
Why Choose Attorney911 for Your Trampoline Case?
Most firms see a trampoline case as a “recreational accident.” We see it as a mechanical and corporate failure. We bring the same federal-court intensity we used in BP refinery litigation to the parent corporations behind Urban Air and Altitude.
As client Chad Harris said, “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.” We treat your child’s recovery fund as if it were for our own family. We pay for the biomechanical engineer who reconstructs the double-bounce. We pay for the pediatric orthopedist who forecasts the growth-plate prognosis. You pay nothing until we win.
We aren’t just local to City of Richland Hills. We are a nationwide authority based in Texas. Our Houston, Austin, and Beaumont offices are our launch point. Our knowledge of trampoline injury law covers every state.
Your child’s case is decided by what gets preserved this week. The DVR overwrites. The attendant transfers. The foam pit refills. Call 1-888-ATTY-911. Hablamos Español. Our spoliation letter goes out within 24 hours of your retention. The case starts today.
What happened to your child wasn’t an accident — it was the predictable output of a system. The AAP has been warning since 1999. ASTM F2970 was written by the industry to establish a safety floor. The park chose to operate below that floor. The waiver was drafted by lawyers who hoped you wouldn’t call us.
