“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.”

This is Kaitlin “Kati” Hill, a mother who lived through every parent’s nightmare. Her three-year-old son, Colton, was at a “Toddler Time” session—a time of day when parks are supposed to be safer for smaller children. But when a larger child double-bounced him, Colton’s femur, the strongest bone in the human body, snapped. Kati told ABC News, “We had no idea. We would have never put our baby boy on a trampoline if we had known.” Her warning post was shared more than 240,000 times because parents across City of Hurst and the DFW Metroplex felt that same chill.

At The Manginello Law Firm, we see the aftermath of these “birthday fun” days every week. We represent the parent sitting at a hospital bedside in a Tarrant County pediatric trauma center, listening to a surgeon explain why a growth plate destroyed at age eight means a decade of surgeries ahead. Since 1998, Ralph Manginello has spent 25+ years making corporate defendants accountable. We’ve gone toe-to-toe with Fortune 500 giants like BP, Walmart, and Amazon. The parent conglomerates behind national trampoline park chains in City of Hurst do not bring anything we haven’t beaten before.

If your child was hurt at a trampoline park in City of Hurst, you have likely already been told that the waiver you signed ends your case. The park’s risk management team wants you to believe it. Their insurance adjuster might even offer you a “friendly” medical-payment check to cover your ER copay in exchange for a signature on a release form.

Do not believe them, and do not sign anything.

A trampoline injury at a commercial facility is almost never a “freak accident.” It is the predictable output of a system that prioritizes throughput and profit over pediatric safety. Our firm is built to pierce that system. We bring an insider’s advantage: our team includes an attorney, Lupe Peña, who used to sit on the other side of the table defending recreational businesses and insurance companies. He knows their scripts. He knows exactly where their waivers are full of holes. He knows that in the City of Hurst, as in every city in America, a business decision made for margin at the corporate headquarters of Unleashed Brands in nearby Bedford or Sky Zone in Provo is often what actually broke your child’s bone.

The Business Decisions Behind “Accidents” in City of Hurst

We don’t look at a broken limb as bad luck. We look at it as the result of a business decision. When a 200-pound adult lands on a trampoline bed while a 50-pound child from City of Hurst is pushing off, the energy transfer multiplies that child’s launch force by up to 4x. This is basic physics. The trampoline bed doesn’t know it’s a “family fun day”; it only knows kinetic energy.

ASTM F2970 is the safety standard the trampoline park industry actually wrote for itself. It requires parks to separate jumpers by age and weight. When a park in the City of Hurst fails to enforce those ratios on a Saturday afternoon because they wanted to sell more wristbands than they had monitors to supervise, that is a violation of their own industry’s floor.

Every trampoline park chain, from Sky Zone and Urban Air to Altitude and DEFY, operates under a layered corporate structure designed to shield the money from the victims. You see a local park in the City of Hurst; we see an Operator LLC, a franchisee holding company, a franchisor, a brand parent like Sky Zone, Inc. (formerly CircusTrix), and a private-equity sponsor like Palladium Equity Partners or Seidler Equity Partners.

We go after every layer.

In Harris County, a jury returned an $11.485 million verdict against Cosmic Jump—one of the largest in the nation—after a teenager fell through a torn trampoline slide onto bare concrete. The park argued there was a waiver. The jury found gross negligence anyway. We believe this is the benchmark for accountability. Your child’s case in City of Hurst is decided by what gets preserved this week. Park surveillance DVRs in City of Hurst typically overwrite in as little as 7 to 30 days. Incident reports get “revised” on digital databases. Foam pits get refilled. Attendants quit or move to new jobs at the Urban Air in Southlake or the Altitude in Fort Worth.

Our spoliation letter goes out within 24 hours of your retention. We freeze the evidence before it vanishes.

The Regulatory Vacuum and the Tarrant County Reality

Many parents in City of Hurst assume that if a trampoline park is open, a state or federal inspector has signed off on it. The truth is much more dangerous. There is zero federal oversight of commercial trampoline park facilities. The Consumer Product Safety Commission (CPSC) can recall a product, but they don’t inspect the building on Loop 820 or Precinct Line Road.

In Texas, the regulatory gap is even wider. While New York has strict laws (GBL Article 12-C) requiring permits, annual inspections, and minimum $500,000 insurance policies, two bills that would have increased safety inspections for Texas trampoline parks died in the 88th Legislature. The Texas Department of Insurance only regulates the “Class B” inflatable rides inside these parks—like the Sky Rider or bungee tramps. The actual trampoline decks where most injuries in City of Hurst happen are statutorily excluded.

This means you are jumping at your own risk in a way most families don’t understand until they’re in a trauma bay. Because the state won’t regulate them, we use the law to discipline them. Our active litigation includes a $10 million lawsuit against the University of Houston for rhabdomyolysis and acute kidney failure. This is the same pathology we see in children who jump for two hours in a hot DFW-area park without proper hydration or breaks. We know the myoglobin cascade, we know the nephrology experts, and we know how to hold institutional defendants responsible for failing to protect the people in their charge.

Why the Waiver You Signed in City of Hurst Isn’t a Wall

When you clicked “I Agree” on that iPad at the front desk, the park’s lawyers wanted you to feel like you were giving up your child’s future. They were wrong. In Texas, the Munoz v. II Jaz Inc. ruling from a Houston appellate court established that a parent cannot bind a minor child to a pre-injury waiver. While the 2025 Texas Supreme Court decision in Cerna v. Pearland Urban Air made it harder by enforcing certain “delegation clauses” that send matters to arbitration, it did not end the fight.

We attack waivers in City of Hurst on five distinct fronts:

  1. Gross Negligence Carve-Out: Even if a waiver covers a slip-and-fall, it cannot cover gross negligence—the conscious disregard of a known risk. If a park in City of Hurst knew a mat was thinning or that their monitor-to-jumper ratio was half of what it should be, the waiver doesn’t apply.
  2. Inadequate Conspicuousness: Texas follows the Dresser v. Page Petroleum “fair notice” doctrine. If the waiver wasn’t bold, all-caps, and explicitly naming “negligence,” it may be void. We often find that kiosk screens in City of Hurst fail this test.
  3. Parental Indemnity Prohibitions: We rely on the long-standing rule that your signature cannot extinguish your child’s separate legal claim for their injuries.
  4. Bilingual Formation Issues: Under the Delfingen doctrine, if your family speaks Spanish and the park presented an English-only, high-pressure digital waiver without a translation, there was no “meeting of the minds.” Lupe Peña speaks Spanish natively and handles these cases directly—sin intérpretes.
  5. Scope of Consent: Did the waiver cover a 30-foot fall from a harness that wasn’t attached? Or a MRSA infection from a foam pit that hasn’t been cleaned in six months? We argue that these risks are not “inherent” to jumping but are separate acts of negligence.

You pay nothing unless we win. We advance every cost—the biomechanical engineer to reconstruct the impact, the pediatric orthopedic specialist to assess the growth plate, and the life-care planner to calculate the next 40 years of medical needs.

What Happened: Trampoline Accident Mechanisms in City of Hurst

The physics of a trampoline injury are violent and often misunderstood by the staff hired to prevent them. If you were injured or your child was hurt at a facility in City of Hurst, it likely fits one of these documented failure modes.

The Double-Bounce Energy Transfer

This is the “catapult” mechanism. When two people of different weights share a trampoline bed, they aren’t just jumping together; they are transferring energy. A 180-pound adult landing on the mat at the exact moment a 60-pound child is starting their jump can multiply the child’s launch force by four times. The child’s bones—which are more pliable and cartilaginous than adults’—cannot absorb the landing. This is the primary source of pediatric femur fractures and Salter-Harris growth plate injuries in City of Hurst.

Foam Pit Submerge-Entrapment

Foam pits in City of Hurst look like soft clouds. They are actually deep wells of open-cell polyurethane cubes that compact under use. ASTM F2970 and the new EN ISO 23659:2022 standards require specific depths and maintenance. If the foam hasn’t been rotated or replaced, a jumper entering feet-first can “bottom out” on the concrete or hard pad beneath. If they enter head-first, their head wedges while their body weight continues forward, snapping cervical vertebrae.

The industry knows this. That is why chains like Sky Zone and Urban Air are increasingly replacing foam pits with airbags. The existence of these safer alternatives is evidence that the foam pit your child used in City of Hurst was a known hazard.

Interconnected Court Entrapment

Most parks in the DFW metroplex use interconnected beds separated by padding. If that padding has slipped or the springs beneath have lost tension, a jumper’s foot can slide into the gap. We see comminuted fractures of the tibia and fibula when a leg is trapped while the rest of the body’s momentum continues to travel forward.

Harness and Attraction Failures

Urban Air and Altitude parks have moved toward a Family Entertainment Center (FEC) model, adding climbing walls, ropes courses, and indoor coasters like the “Sky Rider.” In Sugar Land, a teenager fell 30 feet because an attendant strapped the harness but failed to clip the safety cable. In Newnan, Georgia, a six-year-old was strangled by a Sky Rider cord. We investigate the “chain-wide patterns” of these attractions—if an Urban Air in another state had a harness failure, the park in City of Hurst was on notice.

Extended-Jumping Rhabdomyolysis

If your child jumped for ninety minutes on a hot Saturday afternoon at a DFW park and later complained of severe muscle pain and “iced tea colored” urine, they may be in acute kidney failure. Exertional rhabdomyolysis happens when muscle tissue literally breaks down and enters the bloodstream. We are one of the only firms in Texas with an active litigation desk for rhabdo cases, leveraging our $10 million UH case knowledge for City of Hurst families.

Sanitation-Vertical: MRSA and Staph

Foam pits are impossible to sanitize. They absorb sweat, saliva, and skin cells from thousands of patrons. A small floor burn or abrasion in a City of Hurst park can become a gateway for Methicillin-resistant Staphylococcus aureus (MRSA) or Group A Strep. If your child developed a deep skin infection or cellulitis within 72 hours of visiting a park, the lack of cleaning protocols is a premises liability issue.

The park has a risk team already looking for reasons to blame your child. Call us at 1-888-ATTY-911 so we can look for the truth.

Who is Responsible: The Multi-Layer Defendant Stack in City of Hurst

When we file a lawsuit for a City of Hurst family, we don’t just sue the “park.” We perform corporate structure archaeology to find where the actual insurance money lives. The operator LLC at the Hurst-Fort Worth Sky Zone or the Bedford Urban Air is often just the beginning.

1. The Operator LLC (The Local Franchisee)

This is the entity that signed the lease and hired the 17-year-old monitor who wasn’t watching the court. They usually carry a $1 million primary liability policy. In a catastrophic pediatric case, that policy isn’t even enough to cover the first year of rehabilitation.

2. The Franchisor (Sky Zone Franchising, Urban Air Franchise Holdings)

The franchisor provides the “Operations Manual.” They tell the owners in City of Hurst how to train staff, how many monitors to have per court, and how often to inspect the equipment. When a franchisor retains this much control over safety, they are on the hook. In the Damion Collins case, an arbitrator found “systemic failure” by the franchisor and allocated 40% of a $15.6 million award to them.

3. The Brand Parent (Sky Zone, Inc. / Unleashed Brands)

Unleashed Brands (Urban Air’s parent) was acquired by Seidler Equity Partners in 2023 “amid lawsuits” targeting the franchisor. Sky Zone, Inc. (formerly CircusTrix) is owned by Palladium Equity Partners. We look for decisions made at the private-equity level—like cost-cutting on staff training—that directly led to the injury in City of Hurst.

4. Component Manufacturers

The trampoline beds, the foam cubes, the climbing wall harnesses (like those made by Ropes Courses, Inc.), and the go-karts all have separate manufacturers. If a weld snapped or a harness unbuckled, we bring product liability claims against the people who built the gear.

5. Social Host or School District

If the injury happened during a City of Hurst school field trip or a daycare outing, these secondary venues may share liability for failing to vet the safety of the park. If a birthday party host signed the “master waiver” but you never signed one for your child, that is a tactical gap we exploit to bypass the waiver defense entirely.

We’ve seen what trampoline parks do after a catastrophic injury. We know how to stop them. Call 1-888-ATTY-911.

Catastrophic Pediatric Injuries: Why Biology Matters

A “broken bone” in an adult is a different legal event than the same injury in a three-year-old in City of Hurst. Children’s bodies are biomechanically distinct, and the medical literature—including the 2024 Pediatrics and AJR radiographic essays—confirms that trampoline impacts cause specific, permanent damage.

Salter-Harris Growth Plate Fractures

The growth plate (physis) is the soft tissue at the end of a long bone where growth happens. Because it is cartilage, it is weaker than the surrounding bone. A Salter-Harris Type III or IV fracture can cause the plate to close prematurely. This means while your child continues to grow, that specific leg or arm stops. The result is limb-length discrepancy that may require corrective osteotomy (bone-breaking surgery) years later. We build these “delayed manifestation” costs into our life-care plans.

SCIWORA (Spinal Cord Injury Without Radiographic Abnormality)

This is a pediatric phenomenon that haunts foam-pit cases. Because a child’s spine is ligamentous and flexible, the spinal cord can be severely torque or stretched while the bones remain intact. A CT scan in a Hurst-area ER may look “normal,” but the child is slowly losing sensation. We know to ask for the T1/T2-weighted MRI sequences that most generalists overlook.

Vertebral Artery Dissection and Pediatric Stroke

Attempted flips into a foam pit or onto a mat can cause the vertebral artery—which runs through the neck—to shear. This produces an “intimal tear” where blood clots and causes a stroke. The Elle Yona case (which went viral on TikTok with 27 million views) was initially misdiagnosed as a panic attack. We ensure our City of Hurst clients are evaluated by pediatric neurologists who recognize these patterns as trampoline-specific neurovascular trauma.

Traumatic Brain Injury (TBI) and Diffuse Axonal Injury

A head impact on concrete—like in the Cosmic Jump Houston case—often causes “shearing” of the brain’s white matter. This isn’t just a concussion; it’s permanent damage that affects executive function, academic performance, and personality. We retain pediatric neuropsychologists to establish a cognitive baseline, which is often the “hidden” damage element that doubles the settlement value.

Amputation and Nerve Death

Extreme crush injuries, particularly in interconnected courts where a limb is caught between the mat and frame, can lead to compartment syndrome. If the pressure isn’t relieved by emergency fasciotomy within six hours, muscle and nerve tissue die. This remains one of the most litigated categories because the failure to monitor the court is the direct cause of the delay in medical help.

You pay nothing unless we win. Zero upfront costs. We advance every expense—the biomechanist, the pediatric orthopedic consultant, the life-care planner. Your child’s recovery fund stays intact. Call 1-888-ATTY-911.

Evidence Preservation: The 7-to-30-Day Window in City of Hurst

The minutes after a trampoline accident in City of Hurst are pure chaos. Your focus is on your child, as it should be. The park’s focus is on risk mitigation. According to public parent reviews of Urban Air Southlake, staff were allegedly told to “down-play injuries.”

While you are at the hospital, the clock is ticking on the evidence we need to win.

  • Surveillance DVR Overwrite: Parks in the Hurst/Bedford area do not keep video forever. Most systems are set to overwrite every 7 to 14 days. If we do not send a formal spoliation demand, the “glitch” that happened in the Mathew Knight case (where four cameras failed simultaneously) happens in your case too.
  • Waiver Metadata Purge: Digital waivers are stored on cloud servers. We subpoena the metadata (IP address, device ID, and timestamp) to see if the signature was actually valid or if a minor “clicked through” on their own.
  • Incident Report Sanitization: The first report filled out by the teen monitor usually has the truth. The one they send to the insurance carrier 48 hours later has been reviewed and “corrected” by a supervisor. We demand both versions and the electronic edit-trail.
  • Foam Pit Decontamination: If the foso was compacted or unsanitary, every hour that passes allows the park to rotate the blocks—destroying the evidence of the hazard.

We use forensic digital tools—Cellebrite for mobile extraction, Magnet AXIOM for cloud-based incident reports, and the Wayback Machine to capture what the park’s safety claims were before they edited the website.

As client Angel Walle said, “They solved in a couple of months what others did nothing about in two years.” Speed is our superpower in Tarrant County.

The “Not Call 911” Pattern and Gross Negligence

Wait times matter. The “Not Call 911” instruction documented in Southlake and seen across national chains like Sky Zone represents more than poor customer service—it is a tactical move to prevent an official paper trail and EMS arrival while witnesses are still present. This conduct moves a case from “unfortunate accident” to gross-negligence territory under Transportation Insurance Co. v. Moriel.

In Texas, proving gross negligence removes the caps on punitive damages. It means we aren’t just fighting for medical bills; we are fighting to punish a corporate entity that consciously disregarded your child’s life for the sake of their image.

Most personal injury firms can’t tell you what ASTM F2970 requires of a trampoline park. We can cite it from memory—attendant-to-jumper ratios, court spacing, foam pit depth, age-separated jumping zones. When we depose the park’s operations manager, we know their standards better than they do.

Damages: What a City of Hurst Trampoline Injury Case is Worth

We are often asked what the “average” settlement is. There is no average. There is only what your child needs to reach their maximum medical improvement and what they have lost in potential.

A Salter-Harris fracture at age eight is not “a broken ankle.” It’s a decade of orthopedic monitoring, possible corrective osteotomy, and a damages calculation that anchors in the $500K-$2M range nationally. A cervical spinal cord injury requires life-care planning that covers 24-hour attendant care, ventilator costs, and durable medical equipment for 70+ years—often exceeding $10M to $25M.

The Hidden Damages We Find:

  • Educational Accommodations: Post-concussive syndrome in a City of Hurst student means IEP meetings, tutoring, and academic regression.
  • Tax-Adjusted Life Care Plans: Most firms use nominal dollars. We use present-value-adjusted forecasts that account for medical inflation.
  • Parental Career Impact: The wages a Hurst parent loses during months of “body cast life” are compensable.
  • Hedonic Loss: The loss of the ability to play sports, dance, or simply play with City of Hurst siblings.

If you lost your child at a trampoline park, the most important thing we can tell you is this: it was not an accident, and it was not your fault. It was the predictable output of decisions made by people who put margin ahead of your child’s life. We will name them. We will hold them accountable.

Frequently Asked Questions for City of Hurst Families

“Can I sue if I signed the paper waiver?”

Yes. In City of Hurst, as in most of Texas, a parent cannot waive a child’s personal injury claim. Furthermore, waivers are legally toothless against gross negligence or equipment failures that go beyond the “inherent risks” of jumping. If the park monitor wasn’t watching, the waiver doesn’t cover that.

“What should I do if my child got hurt at a Sky Zone in City of Hurst?”

Seek trauma care immediately at Cook Children’s or the nearest Level 1 pediatric center. Do not give a statement to the park. Take photos of the court. Call us at 1-888-ATTY-911 to send a spoliation letter before the security footage disappears.

“How much money can my family get for a trampoline injury settlement?”

It depends on the severity and whether we can reach the franchisor’s deeper insurance layers. Settlements can range from five figures for a simple fracture to eight figures for paralysis or TBI. We look for every layer of insurance, from the local franchisee to the global brand parent.

“Is the foam pit really safe for my kid?”

According to the Teague 2024 study in Pediatrics, foam pits have an injury rate of 1.91 per 1,000 jumpers—nearly double the rate of standard trampolines. Many are compacted beyond safety specs. If your child was hurt in a pit, the maintenance log is our first discovery target.

“Can I sue the trampoline manufacturer?”

If you were injured on a backyard trampoline from Jumpking, Skywalker, or a Bouncepro from Walmart, you may have product liability claims. These cases aren’t about who jumped; they’re about frame weld failures (Jumpking 2005 recall) or netting breakage.

“Is dark urine after a trampoline park normal?”

No. It is a sign of rhabdomyolysis—muscle death. It is an emergency. Go to Medical City HEB or the nearest ER and demand a CK blood test. This is often caused by extended jumping in the heat of a Texas summer without mandatory breaks.

“What happens if the trampoline park’s surveillance video is missing?”

If we sent a preservation letter and the video “happens” to be gone, we ask for an adverse inference instruction. Jurors are told to assume the video would have hurt the park. In Georgia, a jury awarded $3.5M after a park’s video “glitched” at the exact moment of an injury.

“Should I let the trampoline park’s insurance company pay my hospital bill?”

Never sign a release in exchange for medical payments. They are trying to “buy” your child’s claim for pennies on the dollar. Talk to a lawyer before accepting any money from an adjuster.

“How long do I have to sue a trampoline park in Texas?”

The standard statute of limitations is two years. For minors, the clock doesn’t start until they turn 18—but waiting years is a catastrophic mistake. The evidence (video, the monitor’s memory, the torn mat) will be gone in months.

Our Texas offices are the launch point. Our knowledge of trampoline injury law covers every city and every state. Whether the injury was at Urban Air Bedford, Sky Zone Hurst, or a Jumpking in your backyard in City of Hurst, we are ready.

Call 1-888-ATTY-911. Hablamos Español. Your child’s case starts now.

What happened to your child at City of Hurst 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 trampoline industry itself after they realized how many kids were being maimed. The park operated below that standard to hit a margin target. The waiver was drafted by corporate counsel who knew it wouldn’t hold in most Texas courts. The surveillance is engineered to overwrite before most families have a lawyer. We were built for exactly this fight.
