“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 the voice of Kaitlin Hill, a mother who lived through the nightmare every parent in Mont Belvieu fears when they walk into a trampoline park or set up a jump mat in the backyard. Her son, Colton, was just three years old when his femur—the strongest bone in the human body—snapped during a “Toddler Time” session designed specifically for children his size. She said later, “We had no idea.” Most families in Mont Belvieu don’t have an idea, until the double-bounce happens, the net fails, or the harness stays unattached.
We are Attorney911, and our firm, led by Ralph Manginello, has spent more than 25 years standing in the gap for families facing these exact moments of catastrophic change. We have seen the trauma bays at Texas Children’s Hospital and Memorial Hermann. We have written the demand letters to the corporate conglomerates that own brands like Sky Zone, Urban Air, and Altitude. We know that when a child coming off a trampoline in a body cast is met by a park manager holding a clipboard instead of calling 911, something is fundamentally broken in the system.
If your child was injured at a trampoline park serving Mont Belvieu—whether it was the Sky Zone in Baytown, the Urban Air in Pasadena or Humble, or an independent facility in the Houston metro—your life changed in a single bounce. The park’s insurance adjuster will tell you that the waiver you signed at the kiosk ended your case before it began. They are wrong. Under Texas law, and under the specific litigation strategies our firm has refined over two decades, that piece of paper is often more of a distraction than a defense. We are here to show you why, and to help your family recover what the law says you are owed.
One Jump, One Landing, One Shattered Life in Mont Belvieu
Mont Belvieu is a community where family life centers around youth sports, backyard gatherings, and weekend trips into the surrounding metro. Whether your child attends Barbers Hill ISD or represents a local club soccer or competitive cheer team, they are likely more familiar with a trampoline mat than a treadmill. In the Houston heat, indoor parks like Sky Zone and Urban Air become the default for birthday parties and summer getaways. But these facilities operate under a business model that prioritizes throughput and margin over the rigid safety standards your child’s skeleton requires.
Nationally, more than 300,000 trampoline-related emergency room visits happen every year. In a high-density area like the Houston corridor, including Mont Belvieu and Chambers County, those numbers represent thousands of local families. A 2024 study in the journal Pediatrics by Teague et al. found that for every 1,000 hours children spend in a foam pit, nearly two will suffer an injury. In high-performance jumping zones, that rate climbs to 2.11 per 1,000. These aren’t just “freak accidents.” They are the predictable outputs of a facility designed for maximum profit.
When we investigate a case in Mont Belvieu, we don’t look for an accident. We look for a business decision. We look for the moment the park decided that staffing one teenager to monitor sixty jumpers was “good enough” for their profit targets. We look for the moment they deferred maintenance on a foam pit that ASTM F2970 requires to be rotated and refilled. We look for the corporate policy that instructs employees to downplay injuries rather than activating 911. Our managing partner, Ralph Manginello, brings federal court experience and a background litigating against multinational corporations like BP to these fights. We have gone toe-to-toe with the biggest corporate defense firms in Texas, and we know their playbook because our team includes attorneys like Lupe Peña, who used to sit on the other side of the table. He knows exactly how these waivers are written and—more importantly—exactly where they are full of holes.
The Industry Standard the Park Violated
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 set of safety standards that the commercial trampoline park industry drafted for itself. It isn’t a government rule; it’s the industry’s own floor for what constitutes “reasonable care.” When a park violates these standards, they are operating below the safety minimum they agreed to meet.
In Mont Belvieu, whether in a park or a backyard, these four standards usually define the duty of care:
- ASTM F2970-22: The primary standard for commercial courts. It governs everything from attendant-to-jumper ratios to the depth of foam pits and the cadence of inspections.
- EN ISO 23659:2022: The international standard that many U.S. parks ignore. While Europe and Australia mandate strict, binding safety norms, the U.S. relies on the voluntary ASTM regime. We use the ISO standard to show a jury what “safe” actually looks like globally.
- ASTM F381: The standard for residential trampolines found in Mont Belvieu backyards. It prohibits use by children under age six and requires specific labeling that mass-market manufacturers often fail to make conspicuous.
- AAP Policy Statements (1999, 2012, 2019): The American Academy of Pediatrics has been screaming for a quarter-century that trampolines do not belong in a recreational environment for children. Every park owner in Chambers County is on constructive notice of this medical consensus.
When we depose a park manager, we don’t ask them if they were careful. We ask them why they violated ASTM F2970 Section 10’s attendant-supervision ratios. We ask why they ignored the AAP’s one-jumper-per-mat rule. By the time we are finished, the “accident” has been exposed for what it really was: negligence.
What Really Happens on the Court: The Physics of Injury
Why do these injuries happen so frequently? The answer isn’t “horseplay.” The answer is physics. Trampolines store and release elastic potential energy. In a facility like Sky Zone or Urban Air, those beds are interconnected, creating a vibrational environment that allows energy to transfer between jumpers.
The Double-Bounce multiplier
The most dangerous mechanism is the double-bounce. When a 200-pound adult lands on a mat at the same instant a 60-pound child from Mont Belvieu is pushing off, the energy transfer multiplies the child’s launch force by up to four times. The child isn’t jumping anymore; they are being catapulted. This is the mechanism responsible for the “trampoline fracture”—a distal tibial physis injury that can destroy a growth plate in seconds.
The Foam Pit Illusion
Foam pits look soft. To a child, they look like a cloud. To us, they are a hazard. If the foam blocks are compacted, degraded, or if the pit is shallow (like the 2-foot-8-inch pit that killed Ty Thomasson), the jumper’s head wedges between cubes while their body weight continues forward. This produces cervical hyperflexion or axial compression. The result is often SCIWORA (Spinal Cord Injury Without Radiographic Abnormality), where a child’s neck is broken but the first CT scan looks normal.
Harness and Attraction Failures
Modern parks are bolting on ropes courses, climbing walls, and “Sky Rider” zip-line coasters. These attractions introduce mechanical failure points. In 2019, 12-year-old Matthew Lu died at an Altitude park when staff failed to secure his harness correctly. In 2025, six-year-old Emma Riddle was killed by a go-kart mechanical failure at an Urban Air. These are not trampoline injuries—they are systemic safety failures at multi-attraction venues.
If your child was hurt at one of these attractions, the evidence is already evaporating. Park surveillance DVRs in the Houston area are often set to overwrite in as little as 7 to 30 days. Incident reports get “revised” once the risk management team gets involved. We send a spoliation letter within 24 hours of being hired. We move faster than the overwrite cycle.

Who is Responsible? Piercing the Corporate Shield
The trampoline industry has spent millions of dollars building corporate structures designed to hide the money. When you look at local parks around Mont Belvieu, you aren’t looking at one company. You are looking at a stack of entities engineered to protect the deep pockets at the top.
Currently, the industry is dominated by two massive private-equity-backed towers:
- Sky Zone, Inc. (formerly CircusTrix LLC): Owned by Palladium Equity Partners since 2018. They operate Sky Zone, DEFY, and Rockin’ Jump as sister brands.
- Unleashed Brands: Owned by Seidler Equity Partners since 2023. They own Urban Air, along with brands like Sylvan Learning and The Little Gym.
When we sue, we don’t just sue the local LLC. We perform corporate archeology. We name the operator, the franchisee, the franchisor, the corporate parent, and the PE sponsor. We do this because the local LLC usually only carries a $1 million primary insurance policy. A catastrophic pediatric spinal cord injury can cost $15 million or more over a lifetime. To get that, you have to go upstream.
Our firm is the only Texas practice with a live medical-litigation architecture for rhabdomyolysis and compartment syndrome. We are currently litigating a $10 million lawsuit against the University of Houston involving these exact muscle-and-organ breakdown pathologies. We have the expert nephrologists and medical chronology specialists needed to prove that extended jumping in a heated, unhydrated indoor park wasn’t just “tiring”—it was a medical emergency that caused your child’s kidneys to shut down.
The Waiver is Noise, Not a Wall
The single biggest myth the trampoline industry promotes in Mont Belvieu is that a signed waiver ends your case. It is the first thing the insurance adjuster will mention. It is the first thing the kiosk attendant will point to. And in most cases, it is noise.
In Texas, waivers are subject to the “Fair Notice” doctrine established in Dresser Industries v. Page Petroleum. If the release wasn’t conspicuous—if the font was too small, if the signature was rushed, or if the specific word “negligence” wasn’t used correctly—that waiver is vulnerable. But more importantly for parents: Texas courts have long held that a parent cannot sign away a child’s legitimate tort claim in advance. In Munoz v. II Jaz Inc., the court was clear: a parent’s signature does not bind the child.
Furthermore, no waiver in the United States protects against gross negligence. In Harris County, the Cosmic Jump $11.485 million verdict proved this point. The park had a signed waiver. The jury didn’t care. They found that the park’s decision to let a child jump on a known-torn trampoline was a conscious disregard for his safety. That finding unlocked $6 million in punitive damages.
Our associate attorney, Lupe Peña, used to sit across from firms like ours, defending these waivers. He knows which clauses are written to intimidate you and which ones will actually hold up in a Chambers County courtroom. That insider knowledge is our clients’ greatest asset.
Catastrophic Injuries: Why Medical Specificity Matters
When a child is hurt on a trampoline, the injury is rarely “just a broken bone.” Because pediatric bone is more pliable and less ossified than adult bone, force transmits through the skeleton in dangerous ways. We build cases around the medicine, using terms that force insurance adjusters to sit up and take notice.
- Salter-Harris Fractures: We don’t say “broken ankle.” We say “Salter-Harris Type II fracture of the distal tibial physis.” This diagnosis means the growth plate was destroyed. Your child’s leg may stop growing or grow crooked. The damage we measure today is nothing compared to the limb-length discrepancy we’ll be measuring when they are fourteen.
- SCIWORA: Spinal Cord Injury Without Radiographic Abnormality. We represent the parents who were told by an ER that their kid was “fine,” only to find them unable to move six hours later.
- Traumatic Brain Injury (TBI): The shearing of axonal fibers in a developing brain doesn’t always show up on a standard CT. We use specialists who look for the subtle cognitive decline, the academic regression, and the personality shifts that follow a trampoline impact.
We represent families in Mont Belvieu because we understand that you aren’t just fighting for an medical bill. You are fighting for your child’s next fifty years. We retain life-care planners who calculate every future surgery, every orthotic replacement, and every hour of physical therapy your child will need until adulthood.
Backyard Trampolines and Attractive Nuisance
While parks get the headlines, nearly 75% of trampoline injuries happen in the backyards of neighborhoods across Mont Belvieu. These cases involve a different legal framework.
If your child was injured on a neighbor’s trampoline, Texas law applies the Attractive Nuisance Doctrine. A homeowner who keeps a trampoline in a way that attracts children—unfenced, with the ladder left on, or with a degraded net—can be held liable even if the child was technically a trespasser.
We also pursue Product Liability claims. If the frame weld on a Jumpking or Skywalker snapped, if the netting on a Bouncepro (Walmart’s private label) tore, or if a SEGMART toddler trampoline posed a strangulation hazard, the manufacturer is on the hook. We cross-reference every incident against the CPSC recall database. Often, the product that injured your child was already one the manufacturer knew was defective.
Homeowners’ insurance usually handles these claims, but you should know that many carriers exclude trampolines. We look for the umbrella policies. We look for the manufacturer’s product liability coverage. We find the person, and the policy, that can make your child whole.
Why 72 Hours Matters More Than 2 Years
The Texas statute of limitations on personal injury is two years. For a child, that clock doesn’t even start until they turn eighteen. You might think you have all the time in the world. You don’t.
The evidence is dying.
- Surveillance video: Deleted or overwritten in 30 days.
- Witnesses: The court monitor who was on his phone will quit and move away within months.
- The equipment: The torn mat will be replaced, and the evidence of the defect will be in a dumpster by Tuesday.
- Insurance: Once a park knows a claim is serious, they start shoring up their “reconditioned” incident reports.
We don’t wait for the two-year clock. Our investigation starts the hour you hire us. We deploy forensic digital examiners to image DVR hard drives. We pull the 911 CAD records to see exactly how long the park delayed the call. We find the former employees who are willing to tell the truth about the staffing gaps.
Frequently Asked Questions for Mont Belvieu Families
Can I sue if I signed the waiver at Urban Air or Sky Zone?
Yes. As discussed, Texas voids parental waivers as to the child’s claim, and gross negligence (like ignoring ASTM standards) defeats a waiver for everyone. Don’t let a piece of paper stop you from seeking accountability.
What should I do if my child has dark urine after jumping?
Go to the emergency room immediately. This is a primary sign of rhabdomyolysis, a catastrophic muscle breakdown. Ask for a CK test. Then call us. We lead the state in this specific medical-litigation area.
Is the park’s insurance company on my side?
No. The “friendly adjuster” call is a tactic designed to get you to give a recorded statement that they will use to blame you or your child. “I think” becomes “uncertainty” in their eyes. The $3,000 “Med-Pay” check they offer is a Trojan Horse; signing it often releases your right to the multi-million dollar claim you actually have.
How much does it cost to hire an attorney?
Nothing upfront. We work on a contingency fee. We advance every expense—the engineers, the surgeons, the life-care planners. You only pay us if we win for you. Your child’s recovery fund stays intact.
How long does a trampoline injury case take?
A straightforward fracture case may resolve in months. A catastrophic spinal or brain injury case can take two to three years of aggressive litigation to reach the maximum payout. We prepare for trial from day one. When the insurer knows we’re ready for a courtroom, they bring real settlement offers to the table.
Does it matter which brand of park it was?
Yes. We have distinct litigation strategies for the Seidler-owned Urban Air parks versus the Palladium-owned Sky Zone and DEFY locations. We subpoena chain-wide incident history to show a pattern of negligence.
The Guilt is Upstream, Not With You
To the parent reading this in Mont Belvieu: you might be feeling guilty. You think you shouldn’t have taken them there, or you shouldn’t have let them jump. Stop. Every parent does what you did. You read the marketing that said “safe family fun.” You signed the waiver because the line was long. You Handed your child to a monitor the park represented as trained. You did your job. The park did not.
The park accepted your money and, in exchange, accepted a non-delegable duty under ASTM F2970 to keep your child safe. They failed that duty to increase their margin. The guilt doesn’t belong at your kitchen table; it belongs in the corporate boardroom where they decided to cut the staffing ratios. Our job is to put it there.
