“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 how Kati Hill described the moment her three-year-old son’s life changed at a “Toddler Time” session. It is a scream we have heard echoed in the stories of families across the City of Tomball and throughout Harris County. We represent families who walked into a place like Urban Air or Sky Zone for a Saturday afternoon of fun and walked out with a child in a body cast or a teenager facing a lifetime of neurological deficit.
What happened to your child in City of Tomball wasn’t a “freak accident” or an “unlucky break.” It was the predictable output of a business model that puts profit margins ahead of pediatric safety. For over 25 years, Ralph Manginello and our team at Attorney911 have stood at the hospital bedsides of catastrophic injury victims. We have gone toe-to-toe with multinational corporations like BP, Walmart, and Amazon. The private equity sponsors behind the big trampoline chains — Palladium Equity Partners and Seidler Equity Partners — don’t bring anything to the table that we haven’t already beaten in federal and state courts.
If your child was hurt at a trampoline park near City of Tomball, you are likely being told that the waiver you signed at the kiosk ended your case before it began. That is the first lie the insurance adjuster will tell you. In Harris County, a jury recently awarded $11.485 million — including $6 million in punitive damages — against the operator of Cosmic Jump after a teenager fell through a torn trampoline mat onto concrete. The waiver was signed. The jury found gross negligence anyway. We know how to find that negligence, we know how to preserve the evidence before the park overwrites the video, and we know how to hold every layer of the corporate stack accountable.
The Reality of Trampoline Injuries in City of Tomball
Nationally, trampolines send more than 300,000 people to the emergency room every year. In a high-growth, family-heavy area like City of Tomball, those numbers aren’t just statistics; they are neighbors and classmates. When we look at the data published in 2024 by the American Journal of Roentgenology, the reality is stark: up to 1.6% of all pediatric emergency department trauma visits in the United States are now related to trampolines.
Whether the injury happened at a major chain like the Urban Air in the Cypress/Spring area or on a backyard Jumpking or Skywalker trampoline in a neighborhood off Highway 249, the physics are the same. A trampoline is a piece of equipment designed to store and release elastic potential energy. When it is improperly maintained, under-supervised, or designed with latent defects, that energy is released into a child’s developing musculoskeletal system with devastating force.
In City of Tomball, where youth sports and competitive cheer programs often use trampolines for training, the exposure is constant. But there is a massive difference between a coached gymnastics facility and a commercial park where a 17-year-old monitor with two hours of training is responsible for fifty children. We are the firm that bridges that gap. We currently litigate a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure — the same catastrophic muscle and organ breakdown we see in children who spend two hours jumping in a 90-degree indoor facility without hydration protocols. We know the medicine, we know the standards, and we know how to win.
Why the City of Tomball Evidence Clock is Ticking
The most critical thing you need to understand right now is that the evidence of what happened to your child is disappearing. Trampoline parks in the Harris County area typically use digital video recording (DVR) systems that overwrite themselves every 7 to 30 days. If you wait for the park to “get back to you,” the video of the attendant on their phone or the torn mat will be gone forever.
By Day 10, the Saturday afternoon your child was hurt is often erased. By Day 30, the “updated” version of the incident report may be the only one the park produces. We don’t give them that chance. Our spoliation letter goes out by certified mail within 24 hours of your retention. We demand the preservation of the DVR hard drive, the kiosk waiver metadata, and the daily inspection logs.
Every minute the park delays a 911 call — a pattern we have seen documented in reviews like the parent at Urban Air Southlake who claimed staff were instructed not to call emergency services — is a minute the surveillance gets closer to being lost. We stop that cycle. Call 1-888-ATTY-911 today. Hablamos Español. No fee unless we win.
Commercial Trampoline Park Hazards: The Physics of Negligence
Trampoline parks like Sky Zone and Urban Air are no longer just rooms full of mats. They have become “Adventure Parks,” bolting on go-karts, indoor coasters like the Sky Rider, rock walls, and ropes courses. The problem is that the management of these attractions is often handled by the same minimum-wage staff who are already overwhelmed by the trampoline courts.
The Double-Bounce Multiplying Force
The most common mechanism of injury we see in City of Tomball cases is the “double-bounce.” The physics are simple but brutal. When a 200-pound adult lands on a trampoline bed at the same instant a 60-pound child is pushing off, the energy transfer can multiply the child’s launch force by up to 4x. The child isn’t jumping anymore; they are being thrown.
ASTM F2970 — the safety standard the trampoline industry wrote for itself — explicitly requires parks to separate jumpers by size and age. When a park in the Tomball area allows an adult and a small child on the same court, they aren’t just “letting them have fun”; they are violating the industry’s own safety floor. This is not an accident; it is a choice to ignore physics for the sake of moving more people through the door.
Foam Pit Failures and Cervical Injury
Foam pits at parks like Altitude or DEFY looks like a safe place to land. They are often anything but. If a foam pit is not maintained to the depth required by ASTM F2970 (typically around 42 inches of fill), or if the foam cubes have become compacted and small over time, a head-first entry can cause the jumper to strike the hard floor beneath.
Cervical hyperflexion in a head-first landing is the mechanism of C1-C7 fractures and permanent paralysis. The industry knows this. That is why major chains have been replacing foam pits with airbags. A park that still operates a foam pit in Harris County is making a cost decision. They are choosing older, harder-to-sanitize equipment over safer modern alternatives.
The 2024 Pediatrics study by Teague et al. found that foam pit and inflatable bag injury rates were 1.91 per 1,000 jumper-hours. When we depose a park manager, we know these numbers better than they do. We know that the “panic attack” your teen was diagnosed with after a backflip into a foam pit was actually a vertebral artery dissection — a spinal cord stroke — and the park’s failure to maintain that pit is the reason it happened.
Harness Failures: The Sugar Land Precedent
In our own backyard, the Lakhani case against Urban Air Sugar Land showed the horror of what happens when a harness attraction goes wrong. A 14-year-old fell 30 feet from a climbing wall because an attendant reportedly failed to attach the fall-protection equipment.
We see this across the board in multi-attraction parks. Whether it’s an Urban Air go-kart malfunction like the one that killed 6-year-old Emma Riddle in 2025 or a harness failure on a ropes course, the common denominator is a failure of staff training and supervision. A responsibly-operated facility would have a triple-check protocol for every harness. Most parks in the Houston metro rely on a single teenager who is four hours into their first shift.
The “Waiver” Defense: Why It Doesn’t Work in Texas
You signed a piece of glass at the front desk. You clicked “I agree” on a screen full of legalese. Now the insurance company is telling you that you have no rights. In Texas, they are very likely wrong.
The Express Negligence Doctrine
Texas law is unique. Under the Dresser Industries v. Page Petroleum case, a waiver must satisfy the “Fair Notice” doctrine. This means the release must be conspicuous (bold, large font, or highlighted) and it must satisfy the “Express Negligence” rule. If a waiver doesn’t explicitly use the word “negligence” to describe what you are giving up, it often fails as a matter of law.
Minor Children and Munoz v. II Jaz Inc.
This is the most important rule for Tomball parents: In Texas, a parent generally cannot sign away a minor child’s right to sue for personal injuries. The landmark case Munoz v. II Jaz Inc. established that your signature does not bind your child’s personal cause of action. While the park might try to move the case to arbitration based on a “delegation clause” signed at the kiosk (a tactic recently addressed in Cerna v. Pearland Urban Air), the underlying right of the child to hold the park accountable remains.
Gross Negligence Defeats Every Waiver
No waiver in America can release a company from gross negligence. If a park in the Tomball area knew a mat was torn and left it in service, or if they purposely staffed a Saturday rush with half the required monitors, that is gross negligence. It is a conscious indifference to the safety of your child. As the Cosmic Jump $11 million verdict proved, Texas juries will reject a waiver when they see a park that valued its bottom line over a child’s life.
Our associate attorney, Lupe Peña, used to sit on the other side of the table defending businesses against these exact claims. He knows where the holes in their waivers are because he used to try to patch them. Now, he uses that “defense playbook” to help families win.
Catastrophic Pediatric Injuries: The Long Road to Recovery
We aren’t just “personal injury lawyers.” We are advocates for the parent standing at the trauma-bay bedside. A “broken leg” at age seven is not just a broken leg. It is a life-altering medical event.
Salter-Harris Growth Plate Fractures
Because a child’s bones are still growing, a fracture through the growth plate (the physis) can be devastating. A Salter-Harris Type IV or V injury can lead to permanent limb-length discrepancy or angular deformity. The bone that should grow for the next decade simply stops.
When we build your child’s case, we don’t just look at the ER bill from Memorial Hermann Tomball. We work with pediatric life-care planners to calculate the next 60 years of orthopedic monitoring, potential corrective surgeries, and lost career opportunities. A pediatric catastrophic injury isn’t a “settlement”; it is a recovery fund for a lifetime.
Rhabdomyolysis and the “Hidden” Trauma
One of the most dangerous and under-reported injuries we see is exertional rhabdomyolysis. If your child has been jumping for two hours in a hot facility, their muscles can literally begin to break down, releasing myoglobin into the bloodstream. This protein is toxic to the kidneys and can cause acute kidney failure.
If your child has dark-colored urine or severe, rock-hard muscle pain 24 hours after a trampoline park visit, don’t wait. Go to the ER. We are the only firm in Texas with an active $10 million institutional-accountability case involving rhabdo. We know exactly which experts to call to prove that the park’s environment caused your child’s organ failure.
The 10-Step Attorney911 Case Build
We have a system for winning trampoline injury cases. We don’t wait for the insurance company to do the right thing; we force them to see the risk of a Harris County jury.
- Certified Spoliation Demand: Sent within 24 hours to freeze surveillance and records.
- Scene Investigation: Our investigators visit the park immediately to photograph current conditions and equipment.
- Waiver Deconstruction: We pull the metadata to see if the waiver was presented conspicuously and if the signer had authority.
- Staffing Audit: We subpoena time-clock records to prove the monitor-to-jumper ratio failed ASTM F2970.
- Corporate Archeology: We trace the operator LLC up to the private equity parent (Palladium or Seidler) to find the deep pockets.
- Medical Chronology: We build a day-by-day record of your child’s recovery and trauma.
- Expert Retention: We hire biomechanical engineers and pediatric specialists to explain why the injury was foreseeable.
- Chain-Wide Pattern Search: We look for similar incidents at other locations in the franchisor’s system to prove a systemic failure.
- Insurance Discovery: We find every layer — primary GL, umbrella, excess, and franchisor additional-insured.
- Trial Readiness: We prepare every case for a jury from Day 1. That is the only way to get a maximum settlement.
Frequently Asked Questions for Tomball Families
Q: Can I sue if my neighbor’s backyard trampoline hurt my child?
A: Yes. Texas follows the “Attractive Nuisance” doctrine. If a homeowner has a trampoline that attracts children, they have a duty to secure it (fencing, removing the ladder). Even if your child was technically “trespassing,” the homeowner may still be liable.
Q: The park’s insurance company offered us $3,000 for “Med-Pay.” Should I take it?
A: Not without talking to us. That check is a Trojan horse. It often comes with a release form that ends your right to sue for the $500,000 in future surgeries your child may actually need.
Q: How long do I have to file a case in City of Tomball?
A: The Texas statute of limitations is 2 years from the date of injury. However, for a minor child, the clock is “tolled” until they turn 18, meaning they have until age 20. But here is the catch: While the legal clock is long, the evidence clock is short. If you wait more than 30 days, the video that wins your case is likely gone.
Q: What if the employee who saw the accident doesn’t work there anymore?
A: We find them. Trampoline parks have incredibly high staff turnover. We use LinkedIn alumni searches and state labor records to track down former attendants. They are often much more willing to tell the truth once they no longer work for the chain.
Q: We don’t speak English well. Can you still help us?
A: Sí. Lupe Peña es nuestra abogada bilingüe y ella habla con usted directamente. No usamos intérpretes. El caso Delfingen US-Texas v. Valenzuela dice que si el waiver estaba solo en inglés y usted no puede leer inglés, el documento puede ser inválido.

Detailed Analysis of Trampoline Park Chains Serving City of Tomball
Families in City of Tomball are surrounded by a saturated market of commercial jump facilities. While these chains market themselves as safe outlets for energy, their corporate structures are designed to insulate the parent conglomerate from liability when things go wrong.
Urban Air Adventure Park (HQ: Grapevine, TX)
With nearly 50 locations across Texas, including density in the Houston/Tomball corridor, Urban Air is one of the most prolific operators. Their model has evolved into a “Family Entertainment Center” that includes the Sky Rider zipline and electric go-karts.
- The Chain-Wide Pattern: Urban Air has faced a string of Sky Rider zipline strangulations and falls across multiple states. When an injury happens at a local Urban Air, we don’t just investigate Tomball; we subpoena the chain-wide incident history to prove they had notice of a design defect.
- The Collins $15M Arbitration: A Kansas arbitrator recently awarded $15.6 million in a case against an Urban Air franchisee and franchisor. The arbitrator held the waiver was unenforceable because of a “systemic failure” to implement safety changes. We use this precedent to dismantle Urban Air’s “we’re just a franchisor” defense.
Sky Zone, Inc. (Formerly CircusTrix)
Sky Zone is the oldest major chain and now parents both DEFY and Rockin’ Jump as sister brands under the ownership of Palladium Equity Partners.
- The Staffing Gap: Sky Zone locations in Tukwila and Vancouver, Washington, were recently fined nearly $90,000 for child labor violations involving their teenage staff. This is operational evidence we look for in Tomball: if a park won’t follow labor laws for its own staff, why would they follow ASTM F2970 safety ratios for your kids?
- Internal Warning Admissions: In Massachusetts, litigation revealed a Sky Zone internal manual warning staff to “BE AWARE OF THE PADS,” while the customer-facing waiver gave no such specific warning. We know where these internal corporate documents are hidden.
Altitude Trampoline Park (HQ: Fort Worth, TX)
Altitude markets itself as the “fastest-growing trampoline park company in the world.” Rapid growth often comes at the expense of standardized safety enforcement.
- The Matthew LuFatality: In Gastonia, North Carolina, a 12-year-old was killed on an Altitude climbing wall falling onto concrete. Altitude publicly admitted “human error” and removed the attraction. We cite this when a Tomball-area park puts a climbing wall over an inadequately padded subfloor.
- The $100 Liability Cap: Many Altitude waivers contain a clause purporting to cap total liability at $100. We view this as a badge of substantive unconscionability. No Harris County court is interested in enforcing a $100 cap on a $5 million life-altering injury.
Investigating Adjacent Attractions in Harris County
If your child was injured on something other than a trampoline bed, the liability landscape shifts.
- Go-Karts: The Emma Riddle fatality in 2025 involved an electric go-kart that surged forward into a wall. We investigate the software audit logs and the pedal/throttle calibration of the karts used in Harris County parks.
- Sky Rider / Ziplines: These attractions have a documented history of harness cord strangulation. If your child was caught in a harness, we subpoena the design documents from the pass-through manufacturer, UA Attractions, LLC.
- Ninja Warrior Courses: These courses often fall through a “regulatory gap.” While Texas TDI regulates bungee tramps and inflatable obstacles as Class B amusement rides, ninja courses are often uninspected by the state. We use the regulatory ceiling of the Class B rules to prove the ninja course operated below a reasonable duty of care.
The Economic Impact of a Pediatric Trampoline Injury
If your child was hurt, you are currently seeing the bills from the acute care. But in City of Tomball, the true cost of a catastrophic injury is measured in decades.
We retain forensic economists to calculate the Cognitive-Earning Cascade. A pediatric traumatic brain injury (TBI) can lead to academic regression, which leads to reduced college access, which leads to a massive reduction in lifetime earning capacity. A “mild” concussion at age 10 can cost a child millions of dollars in lost wages as an adult.
We also build life-care plans for Post-Splenectomy OPSI Risk. If your child had to have their spleen removed after a collision, they now face a lifetime of sepsis risk. That requires a specific, expensive medical monitoring protocol. Most generalist firms don’t even know what OPSI stands for. We make the defendant pay for the lifetime of vaccinations and vigilance it requires.
A Legacy of Holding Corporate Defendants Accountable
The parent conglomerates behind Urban Air and Sky Zone hire the same kind of heavy-hitting corporate defense firms that BP and big oil companies hire. Ralph Manginello has been in those boardrooms and those federal courtrooms for 25 years. We don’t settle for the “primary policy limits.” We go upstream. We find the franchisee’s umbrella, the franchisor’s additional-insured layer, and the private-equity parent’s excess tower.
What happened to your child at City of Tomball wasn’t just an accident. It was the predictable output of a system that accepts a certain number of broken necks and shattered legs as a cost of doing business. We are the firm that changes that math.
Your child’s recovery cannot wait. The evidence will not wait. Call 1-888-ATTY-911. Hablamos Español. Our Houston team is ready to go to work for you today.
