“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 was Kaitlin “Kati” Hill, a mother whose post was shared 240,000 times after her three-year-old son, Colton, suffered a broken femur at a trampoline park. As she told ABC News, “We had no idea. We would have never put our baby boy on a trampoline if we had known.”

If you are a parent in Todville reading this, you likely find yourself in that same nightmare. Maybe it was a Saturday morning session at the Urban Air in Webster or the Altitude Trampoline Park near the Gulf Freeway. Maybe it was a backyard birthday party in a Todville neighborhood where a neighbor’s trampoline gave way. Whether your child is currently in a trauma bay at Texas Children’s Hospital in the Houston Medical Center or you are just beginning to see the medical bills mount for a Salter-Harris growth plate fracture, we are here to tell you two things: this was not an accident, and it is not your fault.

At Attorney911, led by managing partner Ralph Manginello with over 25 years of courtroom experience, we treat your family like our own. We have gone head-to-head with some of the largest corporate defendants in America, from the BP litigation following the Houston-area refinery explosion to cases against Walmart and Amazon. We understand how the national trampoline park chains—including Sky Zone, Inc. and its Palladium Equity-backed sister brands DEFY and Rockin’ Jump—operate. We know how Unleashed Brands and Seidler Equity Partners have built layers of LLCs and franchisor shields for Urban Air to avoid accountability. Our firm includes attorneys like Lupe Peña, who previously worked on the insurance-defense side for recreational businesses. He literally helped write and defend the waiver language these parks now use as a shield. Today, he uses that internal playbook to dismantle those very same waivers for our clients in Todville and across Harris County.

The commercial trampoline industry in Texas is essentially a self-regulated vacuum. While we litigate a $10 million lawsuit against the University of Houston for life-altering rhabdomyolysis and acute kidney failure, we see the same institutional indifference in the trampoline industry. They take a product that the American Academy of Pediatrics (AAP) has warned against since 1999 and scale it to massive industrial throughput. They rely on “participation agreements” that they hope will stop you from calling a lawyer. They are wrong. In Harris County, a jury awarded $11.485 million—including $6 million in punitive damages—against the operator of Cosmic Jump after a teenager fell through a torn mat onto concrete. The waiver was signed. The jury found gross negligence anyway. We built our practice to find that same accountability for your family in Todville.

The Architecture of a Todville Trampoline Park Incident

When a child is injured at an indoor jump center serving Todville families, the defense lawyer will immediately try to frame the event as a “freak accident” or an “inherent risk of play.” Physics and industry standards tell a different story. The majority of injuries we see in Todville involve the “double-bounce” mechanism. This occurs when a heavier jumper—often an adult or a teenager—lands on the same trampoline bed at the exact moment a smaller child is pushing off.

The energy transfer multiples the child’s launch force by up to four times. The child is no longer jumping; they are being catapulted. This is the physics behind the comminuted femoral shaft fractures and the catastrophic cervical spine injuries we see in Harris County ERs. ASTM F2970, the safety standard written by the trampoline industry itself, requires parks to operationalize age and weight separation. When you walk into a park on a heavy-traffic Saturday near Todville and see a 200-pound adult on the same court as a 60-pound child, you are witnessing a business decision to ignore the safety floor in favor of higher throughput.

It isn’t just the trampolines anymore. Modern “adventure parks” near Todville have bolted on go-karts, ziplines like the Sky Rider, and climbing walls. These attractions introduce mechanical failure points most parents aren’t warned about. In 2019, Matthew Lu, age 12, died at an Altitude Trampoline Park in Gastonia after employees failed to properly secure his harness on a climbing wall over concrete. The park publicly admitted to “human error” and removed the attraction. In 2025, six-year-old Emma Riddle was killed at an Urban Air in a go-kart mechanical failure. Whether it is a harness at a park near Seabrook or a defective transition pad at a facility in Baytown, when the equipment fails, the “inherent risk” defense dies with it.

Why Todville Families Face a 30-Day Evidence Clock

If your child was hurt in the last week, the evidence that will decide your case in a Harris County courtroom is already disappearing. Trampoline park surveillance systems are notorious for short retention cycles. Most DVR units at regional chains like Big Air or Jumping World are set to overwrite in as little as 7 to 30 days. The incident report you filled out at the front desk is being “finalized” on a corporate server, and we know from forensic discovery that these reports are often revised behind the scenes.

Our Todville evidence preservation protocol is immediate. Within 24 hours of being retained, we send a formal spoliation letter to the operator LLC, the franchisee, and the corporate franchisor. We demand the preservation of:

  • Multi-angle surveillance footage including the 4 hours preceding the incident.
  • The original incident report metadata showing every edit made by management.
  • The waiver kiosk audit logs to verify user ID and timestamp metadata.
  • The court monitor shift logs and time-clock records for every attendant on duty.
  • The ASTM F2970 daily inspection logs for the specific court or foam pit.

If a park tells us the video “glitched” or is “unavailable,” we don’t take their word for it. In a documented Georgia case, Mathew Knight was awarded $3.5 million after defense video glitched on four cameras simultaneously at the moment of injury. The jury inferred spoliation. We retain digital forensic examiners who use tools like Magnet AXIOM and FTK Imager to interrogate DVR hard drives and cloud storage. We find the people who used to work the Todville Saturday shifts through LinkedIn and Glassdoor alumni searches. Those ex-employees, often 17-year-olds who were poorly trained and illegally overworked, are our best witnesses to the systemic staffing gaps that caused your child’s injury.

Dismantling the “Participation Agreement” at the Kiosk

The iPad waiver you signed at the front desk before your child started jumping is the defendant’s most valuable asset. They want you to believe it is an ironclad surrender of your rights. In Texas, and specifically under the jurisdiction of the 14th Court of Appeals in Houston, we know exactly how to break that agreement.

First, under the landmark Texas case Munoz v. II Jaz Inc. (1993), a parent cannot bind a minor child to a pre-injury waiver of the child’s own personal injury cause of action. While the Texas Supreme Court’s 2025 ruling in Cerna v. Pearland Urban Air made it easier for parks to compel arbitration via delegation clauses, the child’s right to recover damages for the park’s negligence remains intact. Arbitration is a different forum—it is not a dismissal. Our firm has achieved multi-million dollar results in complex environments; we know how to litigate in a Dallas or Houston arbitration center as aggressively as we do in a Harris County court.

Second, we attack the formation of the waiver. Under the Dresser fair-notice doctrine, a release must be “conspicuous” and must use the word “negligence” explicitly to release the operator for its own carelessness. Many kiosk waivers used by Todville-area parks are presented in tiny, scrollable boxes that no reasonable person would consider conspicuous. Furthermore, under the Delfingen doctrine, if your family’s primary language is Spanish and the park presented an English-only iPad waiver with no translation, the contract may be void for procedural unconscionability. Lupe Peña speaks Spanish natively; if your hablamos-español family was pushed to sign a document they couldn’t read while a Todville birthday party crowd waited behind them, we will use that language gap to defeat the park in court.

The Problem With Foam Pits and Human Biology

Foam pits are among the most dangerous attractions Todville parents encounter. They look soft, but the biomechanics of a head-first or feet-first entry into a foso de espuma are unforgiving. A jumper’s head wedges between foam cubes, causing the skull to decelerate instantly while the body’s momentum continues. This axial loading is the mechanism for C1-C4 fractures and incomplete quadriplegia.

The industry is full of “don’t call 911” protocols. Parents have reported at Urban Air locations in Southlake and Miami that staff were specifically coached by management to downplay injuries and discourage ambulances. If your child was told to “walk it off” after a foam pit landing in a Todville park, they may be a victim of SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). A child’s cervical spine is mobile and ligamentous; the cord can be damaged even if the X-ray in the ER looks normal.

Beyond the mechanical risk, foam pits are biological hazards. Because foam blocks are porous and rarely replaced, they harbor bacteria, sweat, saliva, and urine from thousands of prior saltadores. We have seen cases of MRSA and necrotizing fasciitis—”flesh-eating bacteria”—acquired through small abrasions in foam pits. Because these parks operate in a regulatory gap in Texas, they face no health department inspections equivalent to a Todville swimming pool or restaurant. We treat these as unsanitary premises liability cases and retain epidemiologists to identify the source of the infection.

Catastrophic Pediatric Injuries: Beyond the Initial ER Bill

A “broken leg” is a manageable injury for an adult; for a Todville child, it can be a life-altering disability. Most trampoline injuries in children occur near the growth plate, or the physis. A Salter-Harris Type II fracture of the distal tibia can disrupt the Cartwright signals that tell a bone how to grow. The damage may not be visible on the day of the injury at the Seabrook-area clinic. It manifests years later, at age 12 or 14, as a measurably shorter leg or a crooked gait.

When we build a case for a Todville family, we don’t just look at the hospital bills from Texas Children’s. We build a Life-Care Plan (LCP). We work with:

  1. Pediatric Orthopedic Surgeons to project the growth-plate prognosis and the timing of future corrective osteotomies.
  2. Pediatric Neurologists to evaluate Diffuse Axonal Injury (DAI) following a TBI, which can cause academic regression and executive dysfunction months after the accident.
  3. Life-Care Planners to quantify the 60-year medical cost for a child with a spinal injury.
  4. Forensic Economists to calculate the adult lost-earning capacity for a child who can no longer pursue certain careers due to physical impairment.

If your child has dark-colored, cola-like urine in the days following a Todville trampoline session, they may need an immediate creatine kinase (CK) test for exertional rhabdomyolysis. This is the same pathology we are litigating in our active $10 million UH case. Muscle cells rupture from overexertion or heat-stroke conditions in over-packed indoor parks, leaking toxic proteins that cause acute kidney injury. We are among the only firms in the country with a dedicated medical-litigation architecture for rhabdo trampoline cases.

Liability for Backyard Trampoline Accidents in Todville

While commercial parks are high-throughput risks, the backyard trampolines in Todville’s residential yards produce the highest annual volume of ER visits. If your child wandered onto a neighbor’s property and was hurt, Texas law protects them under the Attractive Nuisance Doctrine. This rule says homeowners must secure conditions that are likely to draw in children of “tender years” who cannot appreciate the danger. An unfenced trampoline with a ladder left in place in a Todville cul-de-sac is the classic definition of an attractive nuisance.

We also look at Product Liability. Major manufacturers including Jumpking, Skywalker, and the Walmart-exclusive Bouncepro brand have faced massive CPSC recalls for frame weld failure and netting straps that give way. In 2005 alone, 1,000,000 Jumpking trampolines were recalled because the frame could break during use. If a mat tore or a spring snapped under a single jumper in Todville, the manufacturer—and the retailer like Amazon or Walmart—may be strictly liable under the Bolger v. Amazon and Greenman v. Yuba Power lineage of cases. We preserve the physical product immediately; we do not let parents throw the defective mat away.

Attorney911: The Structurally Superior Choice for Todville Families

When you call 1-888-ATTY-911, you aren’t getting a call center. You are talking to a firm that has recovered multi-million dollar results for traumatic brain injury and wrongful death. We advance every single case expense. You pay nothing unless we win.

Our moat is our experience with the corporate-defense playbook. We know that Sky Zone’s internal worker manuals have warned employees to “BE AWARE OF THE PADS” while the customer-facing signs say something completely different. We know that EN ISO 23659:2022 is the standard the rest of the world follows, and that U.S. parks choose a lower standard for the sake of profit. We know which insurance adjusters will try to record your statement before your child is even out of the hospital, and we know exactly how to stop them.

Frequently Asked Questions for Todville Trampoline Victims

“Can I still sue if I signed the iPad waiver at the park?”

Yes. In Texas, waivers cannot release “gross negligence,” which is defined as a conscious indifference to an extreme degree of risk. Failing to enforced ASTM F2970 ratio rules while a 200-pound adult double-bounces a 60-pound child is the very definition of gross negligence. Furthermore, under Munoz v. II Jaz, your signature may not bind your minor child’s independent legal claims at all.

“Urban Air is a franchise. Who do I actually sue?”

We go upstream. We sue the operator LLC that holds the lease for the Todville-area park, the franchisee holding company, the franchisor (UATP Management LLC), and the corporate parent (Unleashed Brands). We identify every layer of insurance, from the $1M primary GL policy to the multi-million dollar corporate umbrella towers. The franchisor’s own audit reports, which often identify hidden violations months before an injury, are a primary discovery target.

“How much is my child’s trampoline injury worth?”

There is no “average” settlement because every child’s future is different. However, national benchmarks for catastrophic pediatric injuries range from $1.5M for serious TBI to over $15M for permanent spinal cord injuries. A Salter-Harris growth plate fracture that requires long-term monitoring typically anchors in the $500K-$2M range. We base our demands on a detailed Life-Care Plan, not the adjuster’s low-ball offer.

“What if the injury happened on a neighbor’s trampoline in Todville?”

We look at the homeowner’s insurance and any umbrella policies they may have. While many Todville homeowners’ policies contain a “trampoline exclusion,” we often find that the exclusion was improperly drafted or that a separate personal umbrella policy (PUP) provides a safe harbor. If the trampoline was a defective Jumpking or Skywalker model, we bring the manufacturer into the case to ensure there is a covered pocket for your child’s recovery.

“Why is my child having headaches weeks after the park visit?”

This is common with pediatric TBI. A child’s brain is still developing, and a concussion may not produce academic regression or behavioral shifts for several months. In Harris County, we use pediatric neuropsychologists to establish a cognitive baseline. If the park failed to invoke a return-to-play protocol and your child jumped a second time, they may have sustained second-impact syndrome, a life-threatening complication.

“They won’t give me the surveillance video. What do I do?”

This is why you call us today. We send a formal demand letter that puts the park on notice of their duty to preserve the DVR imagery. If they ignore it and the video is overwritten, we file a motion for sanctions in a Harris County court. A judge may then give the jury an “adverse inference” instruction, meaning the jury is told that the video would have proved the park was negligent.

“Is my immigration status a factor if I file a lawsuit?”

No. Your right to compensation for your child’s injury exists regardless of your status. Our firm is a sanctuary for families seeking justice. All communication with our attorneys, including Lupe Peña, is privileged and confidential. We are not government agents; we are your advocates.

“Does it cost money to start a case against a park chain?”

At Attorney911, it costs exactly zero dollars upfront. We advance the costs of the biomechanical engineers who reconstruct the double-bounce, the ASTM experts who audit the park’s training, and the medical specialists at Texas Children’s who evaluate the growth plate. We take the risk so your family can focus on healing. If we don’t recover money for you, you owe us nothing.

“What should I say to the insurance adjuster who just called?”

Tell them you are represented by Attorney911 and hang up. Do not give a recorded statement. Do not accept a Med-Pay check. As Lupe Peña knows from his time on the defense side, these adjusters are trained to “lock in” your story while you are still in shock. Their first offer is always their lowest.

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

The statute of limitations for personal injury is two years from the date of the incident. However, for a minor in Todville, the clock is “tolled” until they turn 18, meaning they have until their 20th birthday to file. But remember: while the law gives you years, the evidence only lasts weeks. If you wait more than 30 days to call, the surveillance video is gone, the attendants have quit, and the park has had time to “re-label” the equipment.

“Why does my child have brown-colored urine after jumping?”

This is a medical emergency. Dark brown or cola-colored urine is a classic sign of rhabdomyolysis—muscle tissue breaking down and flooding the kidneys with toxins. If this is happening, go to the pediatric ER at Memorial Hermann or Texas Children’s immediately. Then call us. We lead the region in rhabdo-related litigation and understand the myoglobin cascade that links jumping to kidney failure.

“What if the friend’s parent signed the waiver, not me?”

If you were not the one who signed the waiver for your child—if a grandmother, a coach, or a friend’s parent clicked the kiosk during a Todville birthday party—the waiver is almost certainly void as to your family. Texas Family Code § 153.073 is very specific about who has the authority to bind a minor. We use these “signer authority” gaps to invalidate the park’s defense every single month.

Your Todville Trampoline Case: The Manginello Difference

We don’t settle for the primary policy limits when the franchisor’s deep pockets are reachable. We don’t take “guest error” as an answer when the park staffing was at 50% capacity. We don’t ignore the growth plate because the X-ray looked okay on day one. We are built for this fight.

What happened to your child wasn’t just bad luck. It was the output of a system that puts Todville kids on interconnected trampoline beds with twice-the-size teenagers while a 17-year-old monitor watches a cell phone. It was a choice by companies like Sky Zone and Urban Air to operate under voluntary standards in a state that doesn’t inspect them.

The parent companies behind these parks—Sky Zone, Inc., Palladium Equity, Seidler Equity, and Unleashed Brands—have armies of lawyers. So do we. We’ve spent 25 years beating them.

Your child’s case is decided by what gets preserved this week. The DVR overwrites in 7 to 30 days. The incident report gets “revised.” Waiver versions are purged. Staff members quit.
