One bounce. One bad landing. One broken neck. For many families in Waller, that is all it takes for a Saturday afternoon at a trampoline park to turn into a life-altering tragedy.
At the Sky Zone or Urban Air locations serving the Waller area, children are airborne every few seconds. Most of them land safely. But when they don’t, the consequences are often catastrophic. We’ve seen the aftermath: seven-year-olds leaving facilities on stretchers, and parents standing in trauma bay waiting rooms at Texas Children’s Hospital in Houston, clutching a wristband and a signed kiosk waiver, wondering how a “fun” birthday party ended in a body cast.
The industry wants you to believe that what happened to your child was a fluke—a “freak accident” or an “inherent risk” of jumping. We know better. With over 25 years of experience in catastrophic injury litigation, Ralph Manginello and our team at Attorney911 have seen how these facilities operate. Your child’s injury wasn’t an accident. It was the predictable output of a business model that prioritizes throughput and margin over pediatric safety.
Whether your child was hurt at a commercial park along the US-290 corridor or on a weather-degraded backyard trampoline in a Waller neighborhood, you are now facing an insurance machine designed to silence your claim. They have risk management teams, corporate defense firms, and waivers drafted by lawyers to protect their bottom line. You need someone who fights back—a firm that knows the safety standards they violated and the corporate shells they hide behind.
If you are a parent in Waller looking for answers at 11 PM while your child is in recovery, this guide is for you. We represent families. We represent children. And we represent the pursuit of accountability against an industry that has operated in a regulatory vacuum for far too long.
One Second, 4x Force: The Physics of the Double-Bounce in Waller Parks
The most common way children are injured at trampoline parks serving Waller is a mechanism called the “double-bounce.” It happens in two seconds. It usually occurs when a heavier jumper—an adult or an older teenager—lands on the trampoline bed just as a lighter child is pushing off.
The physics are undeniable. The large trampoline beds in commercial courts are interconnected, storing vast amounts of elastic potential energy. When a 200-pound adult lands, that energy is transferred through the bed. If your 50-pound child is in their launch phase, that energy multiplies their launch force by up to 4x. In that moment, your child isn’t jumping anymore; they are a projectile being launched at a velocity their developing bones cannot decelerate.
This is exactly why the industry’s own safety standard, ASTM F2970, requires parks to operationalize age and weight separation. But walk into any park near Waller on a busy Saturday, and you’ll see the reality: toddlers jumping next to teenagers, and parents double-bouncing their own children because no court monitor intervened.
When a child’s femur—the strongest bone in the body—snaps from a double-bounce, the park will point to the “No Double Bouncing” sign. We point to the court monitor who was on their phone or watching three different courts at once. The park cannot outsource its safety duty to a seven-year-old. The duty to enforce those rules rests entirely on the operator.
What Most Waller Parents Don’t Know: The ASTM and AAP Standards
Trampoline parks do not have a federal regulator. There is no agency that inspects these facilities to ensure the foam pits are deep enough or the attendants are trained. Instead, the industry is largely self-regulated through voluntary standards like ASTM F2970.
We cite ASTM F2970 from memory because it represents the safety floor that these parks frequently slip through. It requires specific attendant-to-jumper ratios, mandatory age-segregated zones, and foam-pit maintenance schedules. Most importantly, it was written by the industry itself. When a Sky Zone or Urban Air near Waller violates F2970, they aren’t just being careless; they are violating the very rules their own peers admitted were necessary to keep children alive.
Furthermore, the American Academy of Pediatrics (AAP) has been clear since 1999: trampolines do not belong in a recreational setting for children. They reaffirmed this in 2012 and again in 2019. Every manufacturer and every park operator knows about the AAP warnings. They simply choose to ignore them because warning parents would hurt their profit margins.
In Europe, the EN ISO 23659:2022 standard is mandatory and much stricter than anything we have in the United States. While parks in Waller operate under a voluntary “suggestion” of safety, parks in the UK or France are held to a ceiling that US operators treat as a floor. We believe Waller families deserve better.
The Paper Shield: Does the Waiver at a Waller Park Actually Bar a Lawsuit?
If you’re like most parents, you signed an iPad waiver at the front desk while your kids were tugging at your arm to get inside. Now that your child is hurt, the park’s insurance adjuster will tell you that the waiver ended your case before it began.
Think again. The waiver is noise; it is not a wall.
In Texas, we have specific legal attack vectors to dismantle these waivers. Our associate attorney, Lupe Peña, used to defend insurance companies and recreational businesses against these exact claims. He knows where the holes are because he used to try to patch them.
1. The Gross Negligence Carve-Out
No waiver in Texas can release a company from liability for its own gross negligence. If the park knew a trampoline mat was torn and left it in service, or if they consciously chose to understaff a Saturday shift to save money, they have crossed the line from ordinary negligence into gross negligence.
The Cosmic Jump $11.485 million verdict in Harris County is the proof. In that case, a 16-year-old fell through a torn slide onto concrete and suffered a traumatic brain injury. The jury found gross negligence—and despite the signed waiver, they awarded $6 million in punitive damages. That happened right here in our own backyard, in Harris County. It proves that Texas juries will hold corporate defendants accountable when they gamble with children’s safety.
2. The Munoz Doctrine for Minors
Under the landmark Texas case Munoz v. II Jaz Inc. (1993), a parent generally cannot sign away a minor child’s personal injury cause of action. While the parent’s own portion of the claim might be affected, the child’s right to seek compensation for their injuries often survives.
3. Signer Authority and the Waller Birthday Party Pattern
Waller is a communal place. Frequently, a grandmother, an aunt, or a friend’s parent takes a group of kids to an Urban Air or Altitude. They sign the waiver for everyone. Texas Family Code § 153.073 says only a legal guardian or court-appointed conservator has the authority to sign for a child. If the wrong person signed that waiver in the rush of a birthday party check-in, the waiver’s footing is destroyed as to your child.
4. Conspicuousness and the “Fair Notice” Rule
Texas law requires that a release of future negligence be “conspicuous.” It must be in a contrasting font, bolded, or otherwise highlighted so that a reasonable person would notice it. Kiosk waivers buried in twenty screens of legalese often fail this test. If you didn’t have a fair chance to see it, it might not be enforceable.
The 5-Layer Stack: Who We Actually Sue in a Waller Trampoline Case
When we take a trampoline injury case, we don’t just “sue Sky Zone.” We perform corporate archeology to find the money. National chains are engineered to hide assets. The entity running the park in Waller is often an undercapitalized LLC with a $1 million policy—barely enough to cover the first month of a catastrophic spinal injury.
We go upstream. The 5-layer stack usually includes:
- The Operator LLC: The immediate business on the lease.
- The Franchisee: The multi-unit owner who may own several locations.
- The Franchisor: Large entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings who mandate the safety manuals that the operator ignored.
- The Corporate Parent: Sky Zone, Inc. (renamed from CircusTrix, backed by Palladium Equity Partners) or Unleashed Brands (backed by Seidler Equity Partners).
- The Private Equity Sponsor: The deep pockets who approve the budget cuts that lead to understaffing.
In the $15.6 million arbitration award against Urban Air (Damion Collins case), the franchisor—UATP Management LLC—was held responsible for 40% of the award. The arbitrator found a “systemic failure” to implement safety changes. We use that same architecture to ensure your child’s recovery fund is fully funded by the people who actually made the decisions.
Catastrophic Pediatric Injuries: Why a “Broken Leg” is Never Just a Broken Leg
Pediatric bone biology is distinct from that of adults. Children’s bones are more pliable, and they have growth plates (physes) that are weaker than the surrounding ligaments. When forces from a trampoline rebound through a child’s limb, the result is rarely a simple break.
Salter-Harris Growth Plate Fractures
One of the most devastating trampoline injuries for a child is a Salter-Harris fracture. This is a break that enters or crosses the growth plate. If it isn’t treated by a pediatric orthopedic specialist with a decade-long monitoring plan, the bone may stop growing or grow crookedly. A child injured at age eight may not show the full deformity until age fourteen. We build damages cases that account for the next ten years of medical monitoring and potential corrective surgeries—not just the initial cast.
SCIWORA: The Invisible Spinal Injury
For children in Waller who land head-first in a foam pit, there is a specialized risk called SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). Because children’s spines are so flexible, the spinal cord can be injured even when the bones look normal on a CT scan. The park might tell you they’re fine because they “walked it off.” Six hours later, that child could be facing paralysis. We know the medicine, and we know how to prove that a park’s failure to recognize these precursors is a breach of the standard of care.
The Rhabdo Bridge: A Specialized Medical Conflict
Our firm currently litigates a $10 million lawsuit against a major university involving rhabdomyolysis and acute kidney failure. This is the same pathology we see in children who jump for extended periods in hot, poorly ventilated indoor parks without hydration. When muscle tissue breaks down from overexertion or crush injuries, it releases myoglobin that poisons the kidneys. Most ERs miss the diagnosis initially. Because we are already litigating rhabdomyolysis cases on an institutional scale, we have the medical experts ready to prove why the park is at fault for your child’s kidney injury.
Section E.16: The Foam Pit as a “Bioreactor”
Something most Waller parents never consider is the biological hazard inside a trampoline park. Foam pits are essentially giant sponges that absorb sweat, skin cells, saliva, and urine from thousands of jumpers. The interior of the cubes cannot be sanitized.
The CDC has tracked MRSA and staph infections in athletic facilities for years. In a crowded park, a small abrasion from a trampoline mat can become an entry point for an infection that leads to cellulitis or, in severe cases, necrotizing fasciitis (flesh-eating bacteria).
If your child developed a severe infection shortly after a park visit, the park may be liable for maintaining unsanitary premises. We subpoena the cleaning logs and the foam replacement records. If those logs show that the foam hasn’t been rotated or replaced in months, the waiver doesn’t cover that choice. That’s negligence, plain and simple.
Adjacent Hazards: Go-Karts, Ziplines, and Harness Failures
Contemporary parks serving Waller are now Family Entertainment Centers (FECs). They’ve bolted on go-karts, indoor coasters (like Sky Rider), and 30-foot climbing walls. The problem is that the same minimum-wage teenager supervising the dodgeball court is often the one strapping your child into a harness.
We’ve seen the results. In 2019, Matthew Lu fell over 20 feet to his death at an Altitude park because of a harness failure. The park later admitted “human error” and removed the attraction. In Port St. Lucie in 2025, six-year-old Emma Riddle was killed by a malfunctioning electric go-kart.
When a park expands into mechanical attractions, their risk profile changes. Often, their insurance policy doesn’t even cover the new “extra” attractions. We look at whether the waiver you signed was actually updated to cover a go-kart or if it still only mentions trampolines. A trampoline waiver doesn’t give a park a license to kill a child on a zipline.
The Waller Evidence Clock: Why You Must Act in 7 to 30 Days
The most important thing to understand after an injury in Waller is that the evidence is on a timer.
- Surveillance Video: Most park DVR systems overwrite in 7 to 30 days. If we don’t send a formal spoliation letter within the first week, the footage of your child’s injury likely disappears forever.
- Waiver Metadata: Kiosk databases often purge or “update” version history every few weeks. We need to capture the exact version you saw at the check-in counter.
- Staff Turnover: Trampoline park attendants have an annual turnover rate of 130-150%. The teenager who saw what happened may be gone before you even file a claim.
Our firm doesn’t wait. When you retain us, our spoliation demand goes out within 24 hours. We demand the preservation of the DVR hard drive, the training logs for the attendants on shift, and the maintenance records for the specific court. We use forensic tools like Magnet AXIOM and FTK Imager to extract digital evidence before the park’s risk management team can “revise” the incident report.
Frequently Asked Questions for Waller Families
Can I sue if I signed the paper waiver for my child?
Yes. In Texas, a parent generally cannot waive a minor’s right to sue a commercial business for their own negligence. Furthermore, no waiver covers gross negligence. If the park operated below ASTM F2970 standards, the waiver is often legally irrelevant to the child’s claim.
How long do I have to sue a trampoline park in Texas?
The standard statute of limitations is two years from the date of injury. For a minor, that clock is paused (tolled) until they turn eighteen, giving them until age twenty to file. However, waiting is a tactical mistake. The physical evidence—the surveillance video and the state of the equipment—is usually gone within 30 days.
What should I do if the park manager calls me to “check in”?
Do not talk to them. The “friendly manager call” is an information-gathering tactic for their insurance adjuster. Tell them you are represented by Attorney911 and hang up. Every word you say, including “we’re doing okay,” can be used to minimize your child’s damages later.
How much is my child’s case worth?
Catastrophic trampoline injury awards vary. The $11.485 million Cosmic Jump verdict and the $15.6 million Urban Air award are at the high end for paralysis and brain injury. Even “smaller” cases involving femur fractures or growth plate damage frequently settle in the high six-figure or seven-figure range because the future medical costs for a child are so high. We build detailed Life-Care Plans to quantify exactly what your child will need for the next fifty years.
What happens if the park says the video is “unavailable”?
In Georgia, a jury awarded $3.5 million to Mathew Knight after the park claimed the video of his injury “glitched” on four different cameras at once. Juries do not like spoliation. If the video is missing, we subpoena the IT administrator and the DVR hardware. If the park destroyed video after receiving our notice, we seek an “adverse inference” instruction, which tells the jury to assume the video would have proved the park was negligent.

Verbatim Parent-Query FAQs
“Can I sue if I signed the waiver?”
The quick answer is yes. In Waller and throughout Texas, waivers are heavily scrutinized by courts. They almost never protect a park from gross negligence (like having known equipment defects) or reckless supervision. Furthermore, the Munoz rule in Texas generally prevents parents from waiving the legal rights of their minor children. The waiver is the first thing an adjuster will use to scare you, but it’s often the first thing we defeat in court.
“Should I take my kid to a trampoline park at all?”
As attorneys, we see the worst-case scenarios. The American Academy of Pediatrics has advised against it since 1999. If you do go, we recommend avoiding foam pits (cervical risk), keeping children under six off all equipment (growth plate risk), and never allowing “double-bouncing” with a larger jumper.
“They wouldn’t call 911 — is that legal?”
It is a documented industry pattern. At an Urban Air in Southlake, a parent reported that staff were instructed by management not to call 911 to avoid negative publicity and state reporting triggers. This behavior is evidence of a conscious indifference to patron safety—the very definition of gross negligence. If the park delayed medical care for your child, that is a major component of our liability claim.
“What is a ‘double bounce’ and why is everyone talking about it?”
Double-bouncing is the transfer of kinetic energy from a heavy jumper to a light one through the trampoline mat. It can launch a smaller child with enough force to shatter their tibia or femur upon landing. It is the number one cause of catastrophic fractures in parks near Waller and a direct violation of the ASTM section requiring weight-class separation.
