“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.”

Those are the words of Kaitlin “Kati” Hill, a mother who watched her three-year-old son Colton suffer a broken femur at a trampoline park. Her warning, shared hundreds of thousands of times across social media, resonates with every parent in City of White Settlement who has ever stood in a trauma bay at Cook Children’s Medical Center in Fort Worth, watching a surgical team prepare to set a child’s bone.

At Attorney911, we know that scream. We know the silence of the drive to the hospital through the I-30 and Loop 820 interchange. We know the feeling of a park manager handing you a clipboard and a refund voucher while your child is being loaded into an ambulance. Since 1998, Ralph Manginello has fought for families facing the most devastating medical outcomes imaginable. We have spent over 25 years building an architecture of accountability for catastrophic injuries, traumatic brain injuries (TBI), and wrongful deaths.

If your family’s life changed in one bad landing at a park in City of White Settlement, the first thing you need to hear is this: It was not an accident. It was a business decision.

When a park chooses to staff a Saturday rush with only half the attendants required by the safety standards they drafted for themselves—ASTM F2970—they are deciding that their margin is more important than your child’s spine. When they keep a foam pit in operation even though the blocks have compacted to a depth that no longer prevents a head-first collision with the concrete subfloor, they are accepting the risk of your child’s paralysis.

We are a Texas-based firm with a national reach, and we have memorized the industry’s playbook because one of our attorneys, Lupe Peña, used to sit on the other side of the table defending these very businesses. We know which defenses they try first, and we know exactly how to dismantle the waiver you signed at the kiosk. Whether your child was injured at an Urban Air, an Altitude, a Sky Zone, or on a backyard Jumpking or Skywalker trampoline in City of White Settlement, we are built for this fight.

Why Time is the Enemy in City of White Settlement Trampoline Cases

The legal deadline to file a claim in Texas is generally two years from the date of the injury, and for minors, that clock is often tolled until they turn eighteen. But the evidence clock in City of White Settlement runs much faster.

Commercial trampoline park surveillance DVR systems are typically engineered to overwrite footage on a rolling 7-to-30-day cycle. If you wait three months to call a lawyer, the video of the double-bounce that launched your son is gone forever. The incident report filed by a teenage “court monitor” might be “revised” on the park’s computer system within forty-eight hours to shift the blame onto your child. The broken spring or the torn mat that caused the injury will be replaced before the facility opens the next morning.

Our protocol is aggressive. Within 24 hours of being retained by a family in City of White Settlement, our spoliation letter goes out by certified mail to the operator LLC, the franchisee, the franchisor, and their insurance carriers. We demand the preservation of native-format video, metadata from the waiver kiosk, time-clock records for every employee on shift, and the specific equipment involved in the crash.

We don’t just “handle cases.” We preserve the truth before the park has a chance to hide it.

Call 1-888-ATTY-911. Hablamos Español. Our firm works on a contingency fee basis, which means you pay nothing up front and nothing at all unless we win your case. We advance every expense—from the biomechanical engineer who will reconstruct the impact to the pediatric orthopedic consultant who will project your child’s future care needs. The fight for your child’s recovery fund starts with one call.

The Science of the Slam: How Trampolines Maim Children

A trampoline is a machine that stores and releases massive amounts of elastic potential energy. It was never intended to be a multi-user playground, yet parks in the City of White Settlement area routinely permit “Toddler Time” and birthday parties where children of wildly different sizes share the same equipment.

The physics do not negotiate. When a 200-pound adult lands on a trampoline bed at the same instant an 80-pound child is pushing off, the energy transfer can multiply the child’s launch force by up to four times. The child isn’t just jumping; they are being catapulted by a force their skeleton was never designed to absorb.

The Double-Bounce: A Known Pediatric Catastrophe

Medical literature, including the peer-reviewed work of Nysted and Drogset, has established for two decades that the smaller jumper in a multi-person bounce is approximately 14 times more likely to suffer an injury. In City of White Settlement, we see this manifest as:

  • Comminuted Femoral Shaft Fractures: Shifting our child from a birthday party to a multi-day hospital stay for an open reduction internal fixation (ORIF) surgery.
  • Salter-Harris Growth Plate Injuries: Damage to the cartilaginous zones of the bone that can lead to permanent limb-length discrepancies or angular deformities that may not manifest until your child is fourteen.
  • Tibia and Fibula “Trampoline Fractures”: Transverse or spiral breaks caused by the high-velocity rebound of a trampoline bed.

The American Academy of Pediatrics (AAP) has been warning parents since 1999 that trampolines do not belong in homes or in recreational centers. The industry’s own standard, ASTM F2970, requires parks to separate jumpers by age and weight. When a park in City of White Settlement fails to enforce these zones, they aren’t just being “sloppy”—they are violating the fundamental rules of their own industry.

The Foam Pit Illusion

Foam pits look like soft, safe clouds. They are often the most dangerous attractions in the park. According to Teague et al. in the January 2024 issue of Pediatrics, foam-pit injury rates are documented at 1.91 per 1,000 jumper-hours.

The biomechanics are brutal: a jumper enters the pit head-first, their head wedges between polyurethane foam cubes, and their forward momentum torques the neck. If the pit is compacted—meaning the blocks haven’t been rotated or replaced according to spec—the jumper strikes the hard subfloor through the foam. This is the mechanism behind cervical spinal cord injuries and SCIWORA (Spinal Cord Injury Without Radiographic Abnormality), where a child’s neck is permanently damaged even when a standard CT scan appears “normal” in a City of White Settlement-area ER.

The 5-Layer Defendant Stack: Who Pays for an Injury in City of White Settlement?

National trampoline park chains are masterfully engineered to hide their assets. When you see a sign for a major brand in Tarrant County, you aren’t looking at one company. You are looking at a fortress of LLCs designed to make you believe the “local park” has no money.

We find the money. Our corporate archeology traces the liability through every layer:

  1. The Operator LLC: The local entity in City of White Settlement that signed the lease and hired the staff. They often carry a $1 million primary policy that barely covers the first year of a catastrophic injury.
  2. The Franchisee: The multi-unit owner who may own locations across Texas.
  3. The Franchisor: The brand-owner (Sky Zone Franchising LLC, Urban Air Franchise Holdings, Altitude Franchise Holdings). They mandate the operations manual and training protocols. If their standards were flawed, they are liable.
  4. The Corporate Parent: The conglomerates now owned by private equity firms. Sky Zone, Inc. (renamed from CircusTrix in 2023 and backed by Palladium Equity Partners) and Unleashed Brands (parent of Urban Air, acquired by Seidler Equity Partners in 2023) hire elite-defense firms. We have litigated against the largest corporations in the world, including BP after the Texas City explosion, and we are not intimidated.
  5. The Manufacturers: The vendors who designed the defective harnesses, the unpadded walls, or the unstable trampoline beds.

In cases like Damion Collins v. Urban Air, an arbitrator awarded $15.6 million because the franchisor failed to implement safety changes after a recognized risk of injury. In Max Menchaca v. Cosmic Jump, a Houston jury awarded $11.485 million because the operator knew a trampoline slide was torn and did nothing. We look for those same patterns of conscious indifference in City of White Settlement.

Insurance Beyond the Primary Limit

We don’t accept the adjuster’s claim that “the policy is only $1 million.” We discovery the umbrella policies, the excess layers, and the “additional insured” provisions that often reach $25 million or more in a national chain’s tower. If a backyard trampoline in a City of White Settlement neighborhood was defective, we pursue the product liability policies of manufacturers like Jumpking or the retailer liability of giants like Walmart or Amazon.

Texas Law: The Waiver is Not a Wall

Parks in the City of White Settlement area rely on a single piece of paper to stop families from seeking justice: the waiver you signed on an iPad at the front desk.

Our associate attorney, Lupe Peña, understands these waivers better than the people who hand them to you. He used to defend these clauses from the other side. Today, he uses that insight to break them.

Why Your Signature Might Not Matter

  • Minor Children Are Protected: In Texas, the landmark case Munoz v. II Jaz Inc. established that a parent generally cannot sign away a minor child’s personal cause of action before an injury occurs. Your signature may bar your own claims for medical bills, but your child’s right to be whole lives on.
  • Gross Negligence Carve-Out: Texas courts, following the Moriel doctrine, refuse to enforce waivers when the defendant was “grossly negligent”—meaning they were aware of an extreme risk and proceeded anyway. If accurate staffing logs in a City of White Settlement park show they were operating at 40% of required monitors, that waiver is often legally worthless.
  • The Dresser Fair-Notice Standard: A Texas waiver must be “conspicuous” and express the word “negligence” clearly. If the release was buried in a twenty-screen scroll on a tablet while you were being pressured to finish so your child could jump, it may fail for lack of fair notice.
  • The Delfingen Spanish Attack: If your family’s primary language is Spanish and you were presented with an English-only waiver without a translation or explanation, the case of Delfingen US-Texas v. Valenzuela may invalidate the agreement entirely.

Muchas familias en City of White Settlement hablan español como primer idioma. Si usted firmó un documento en inglés que no podía leer completamente antes de que su hijo se lastimara, tiene derechos que los parques intentarán ignorar. Lupe Peña le hablará directamente, en su idioma, y desmantelará la defensa del parque desde adentro.

Catastrophic Injuries and the Life Care Plan

When we represent a child in City of White Settlement, we aren’t just looking at the emergency room bill. We are looking at the next seventy years.

A “broken leg” is a temporary problem. A Salter-Harris Type IV fracture is a lifetime of orthopedic monitoring. A pediatric Traumatic Brain Injury (TBI) can lead to executive function deficits and academic regression that don’t fully reveal themselves until the child reaches middle school. Rhabdomyolysis—the breakdown of muscles into the blood—can lead to permanent acute kidney failure.

We build a Pediatric Life Care Plan for every catastrophic injury client. We work with board-certified pediatric neurologists, spine surgeons, and vocational economists to calculate:

  • Every future surgery, including hardware removals and corrective osteotomies.
  • Modifications to your City of White Settlement home to accommodate assistive technology.
  • Lifetime occupational and speech therapy.
  • Lost future earning capacity based on your child’s projected professional trajectory.

We are currently litigating a $10 million lawsuit against a major university involving rhabdomyolysis and kidney failure. We bring that same medical expertise to every City of White Settlement trampoline case involving muscle-crush or extended-exertion injuries.

Expert Witness Deployment: Building a Winning Case

Attorney911 doesn’t settle cheap because we don’t build cheap cases. When a trampoline park insurer sees our name on the pleading, they know a panel of nationally-recognized experts is coming with us:

  • Biomechanical Engineers: To model the energy transfer and prove the park’s equipment was dangerously configured.
  • ASTM Compliance Specialists: To testify exactly how many safety rules the City of White Settlement operator broke.
  • Digital Forensic Examiners: To interrogate the park’s DVR and find out why the camera “glitched” at the exact second your child landed. In cases like Mathew Knight v. Georgia Trampoline Park, a jury awarded $3.5 million because the video conveniently failed on four cameras at once. We don’t take “it wasn’t recorded” for an answer.

Frequently Asked Questions for City of White Settlement Families

Should I let the park’s insurance adjuster record my statement?

No. This is the “Recorded Statement Trap.” Anything you say—even a polite “I think she was having fun until…”—will be used to argue your child was being reckless. Hang up and call 1-888-ATTY-911.

The park manager said it was a “freak accident.” Should I believe them?

No. There is no such thing as a “freak accident” in an environment that has produced 300,000 emergency room visits. The American Journal of Roentgenology (AJR 2024) notes that up to 1.6% of all pediatric ED trauma is trampoline-related. It was a foreseeable result of their operational failure.

What if I didn’t sign the waiver, but the friend’s parent who took my kid did?

Texas Family Code § 153.073 is clear: only a parent or legal guardian has the authority to sign legal documents for a minor. If Aunt Mary or the neighbor signed for your child in City of White Settlement, the waiver has no legal standing.

My child has dark-colored urine after jumping. Is this normal?

No. This is a medical emergency. “Cola-colored” or “tea-colored” urine is a hallmark sign of rhabdomyolysis. It means your child’s kidneys are being poisoned by dying muscle tissue. Go to the ER immediately and then contact our firm to discuss the $10 million UH rhabdo case and how it applies to your situation.

Can I sue if the attendant was on their phone?

Active supervision is required by ASTM F2970. If a monitor in a City of White Settlement facility was distracted, the park has breached the most basic duty of care. This is the foundation of a gross negligence claim.

Your Next Steps After an Injury in City of White Settlement

The park has a risk management team working on your file within minutes of the injury. They have attorneys on retainer. They have insurers whose sole job is to protect the billion-dollar conglomerates behind the brand.

You deserve a team that fights harder.

The Reality of Backyard Trampoline Injuries in City of White Settlement

While parks are a massive source of catastrophic injury, thousands of families in City of White Settlement maintain trampolines in their own yards. These are America’s most warned-against consumer products. Brands like Jumpking, Skywalker, and Bouncepro sell products that the AAP has expressly stated since 1999 should not exist in a home environment.

When a backyard trampoline fails—through a frame weld that snaps, a net that tears due to UV degradation, or a spring pad that exposes metal coils—the manufacturer may be liable under strict product liability. Manufacturers have been forced into massive recalls, like the 1,000,000-unit Jumpking recall for breaking welds or the 2026 SEGMART recall for strangulation hazards.

If your child was injured on a neighbor’s trampoline in City of White Settlement, the Attractive Nuisance Doctrine may hold the homeowner responsible even if your child wandered onto the property uninvited. Homeowners’ insurance policies often exclude trampoline injuries, but we know how to look for the umbrella layers that provide coverage when the primary policy fails.

Establishing Foreseeability: What the Industry Knew

The “we had no idea” defense is a lie. Every trampoline park operator in Texas knows the following:

  1. The Medical Record: The AAP (1999, 2012, 2019) and the American Academy of Orthopaedic Surgeons (Position 1135) have warned them for decades.
  2. The Industry-Written Standard: They literally wrote the ASTM F2970 standard themselves to create a legal floor. When they drop below that floor, they are admitting the risk was foreseeable.
  3. The International Benchmark: While U.S. standards are largely voluntary, Europe mandates EN ISO 23659:2022. The fact that Sky Zone or Urban Air operates at a lower safety level in City of White Settlement than they would in Paris or Berlin is evidence of a conscious choice to prioritize profit over safety.

If your child hit the mat and their knees buckled, if they let out that scream, or if you are now adjusting to a wheelchair in your City of White Settlement home, we are here to help. We represent the parent who would have never signed that waiver if they had known the truth.

Justice isn’t a gift from an insurance company. It is something we take from them through evidence, expertise, and a refusal to back down.
