“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 Kaitlin Hill, the mother of three-year-old Colton, telling ABC News about the moment a trampoline park shattered her son’s femur. Her warning post was shared 240,000 times because every parent recognizes that scream. We recognize it because we represent the families who live it.
In City of Liverpool, a weekend trip to a trampoline park in the Greater Houston area is supposed to be a safe way for children to burn off energy. But for many Brazoria County families, it ends in the trauma bay at Texas Children’s Hospital or UTMB. The industry wants you to believe these injuries are “freak accidents” or “inherent risks.” We know better. We have spent over 25 years proving that what happened to your child was the predictable output of a business decision.
Attorney911 was built for this fight. Managing Partner Ralph Manginello brings more than two decades of courtroom experience, including high-stakes litigation against Fortune 500 giants like BP after the Texas City refinery explosion. Our team includes Lupe Peña, a former insurance defense attorney who used to sit on the other side of the table. He knows exactly which arguments the parks use to hide behind their waivers because he used to write them. Now, he uses that insider playbook to dismantle their defenses for families in City of Liverpool.
We are currently litigating a $10 million lawsuit involving rhabdomyolysis and acute kidney failure—the same catastrophic muscle and organ breakdown we see in children who jump for extended sessions in heated parks. Whether your child was hurt at a national chain like Sky Zone, Urban Air, or Altitude, or a regional operator like Cosmic Air or Jumping World, we have the resources to go upstream to the deep pockets. We handle these cases on a contingency fee basis, meaning you pay nothing unless we win.

One Jump. One Bad Landing. One Broken Neck.
At a trampoline park serving City of Liverpool, a seven-year-old can come off a court on a stretcher in less time than it took his parents to sign the kiosk waiver. The double-bounce that shatters a tibia happens in two seconds. The frame pad that wore through, exposing a rusted spring, has been a known hazard for weeks. These aren’t accidents.
Nationally, trampolines send over 300,000 Americans to the emergency room every year. In a metro the size of Greater Houston, which includes City of Liverpool, that share is measured in thousands. The American Academy of Pediatrics (AAP) has advised against recreational trampoline use since 1999. They reaffirmed this warning in 2012 and 2019. Despite 25 years of medical consensus, the industry has exploded into a multi-billion-dollar economy.
When a parent in City of Liverpool watches their child being loaded into an ambulance, the park manager often hands them a clipboard instead of an apology. They hope you believe the piece of paper you signed at the front desk is an automatic shield. It isn’t. Texas courts have repeatedly voided trampoline park waivers for gross negligence, inadequate conspicuousness, and minor-child enforceability problems.

The Standard of Care: ASTM F2970 vs. Reality
Most personal injury firms can’t tell you what ASTM F2970 requires of a trampoline park. We can cite it from memory. This is the safety standard the industry wrote for itself to establish a floor. When a park in the City of Liverpool area operates below that floor, they are choosing margin over your child’s safety.
ASTM F2970 Section 10 requires specific attendant-to-jumper ratios. It requires age-separated jumping zones because of the physics of energy transfer. We also pair every F2970 reference with EN ISO 23659:2022—the mandatory international standard used across Europe. The US is one of the only developed economies where these standards are largely voluntary. That regulatory gap is why litigation is the only way to compel safety in City of Liverpool.
When we depose a park’s operations manager, we know their standards better than they do. We look for the following violations:
- Attendant-to-jumper ratios that collapsed during a birthday party peak.
- Court monitors looking at phones instead of the jumpers.
- Foam pits that are compacted past the 8-inch specification required by F2970.
- Failures to separate a 200-pound adult from a 60-pound child on the same court.
Industry-wide sales for parents like Sky Zone, Inc. topped $642 million in 2024. These companies are backed by private equity giants like Palladium Equity Partners and Seidler Equity Partners. They hire elite corporate-defense firms. We are not intimidated. We’ve already fought those firms and won.
Call 1-888-ATTY-911. Our spoliation letter goes out within 24 hours of your retention. The DVR surveillance video at these parks is often overwritten in as little as 7 to 30 days. We preserve it before it vanishes.
The Physics of the Double-Bounce
Imagine a Saturday afternoon at a Sky Zone or Urban Air serving City of Liverpool. The court is packed. The attendant is a teenager on his second week of work. A sibling pair begins jumping on the same bed. A 180-pound father lands just as his 50-pound daughter is pushing off.
The energy transfer multiples the child’s launch force by up to 4x. The child is no longer jumping; she is being thrown. Her developing bones cannot absorb the landing. She sustains a comminuted femoral shaft fracture requiring ORIF (open reduction internal fixation) with intramedullary nailing.
This isn’t an inherent risk. It is a violation of the “one jumper per bed” rule that ASTM F2970 mandates. If the attendant was doing their job, that injury would never have happened. The park chose to understaff that court.
Who Is Really Liable for Your Child’s Injury?
We don’t just sue the local LLC. We perform corporate-structure archeology to find the money. In a typical City of Liverpool trampoline injury case, we identify at least five layers of potential defendants:
- The Operator LLC: The specific business running the park. Often undercapitalized.
- The Franchisee: The multi-unit entity that may own several locations.
- The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC. They dictate the standards the operator failed to follow.
- The Corporate Parent: The entity now known as Sky Zone, Inc. (formerly CircusTrix LLC) or Unleashed Brands.
- The Private Equity Sponsor: The money behind the cost-cutting decisions.
In Kansas, a $15.6 million arbitration award was issued in the Damion Collins v. Urban Air Overland Park case. The arbitrator, Thomas Bender, found a “systemic failure” by the franchisor and assigned 40% of the fault to the corporate entity. We use that same architecture to hold City of Liverpool area parks accountable.
We also look at the equipment manufacturers. If a net anchor failed or a frame weld broke, manufacturers like Jumpking, Skywalker, or Springfree may be strictly liable for design or manufacturing defects. In Harris County, a jury awarded $11.485 million against Cosmic Jump after a teen fell through a torn slide onto concrete. The jury found gross negligence even though the family had signed a waiver. That is the Texas anchor we bring to your case.
Call (888) 288-9911. We advance every expense—the biomechanist, the pediatric orthopedic consultant, the ASTM specialist. You pay nothing unless we recover for you.
Why the Waiver is Noise, Not a Wall
The insurance adjuster will call you within 48 hours. She will sound concerned. She will ask if you have a moment to “walk through what happened.” This is the Recorded Statement Trap. She is looking for a reason to blame you or your child. Then, she will mention the waiver.
Do not let them push you around with a piece of paper. In Texas, the “fair notice” doctrine and the Munoz v. II Jaz decision provide the attack vectors we need.
- Minor Child Rule: A parent generally cannot waive a minor’s future tort claim in Texas. Your signature does not stop your child from seeking justice.
- Gross Negligence: Waivers cannot legally release a park from gross negligence. If the park knew a foam pit was too shallow and let your child jump anyway, the waiver fails.
- Bilingual Formation: If your family speaks Spanish and the park only provided an English waiver on an iPad, the Delfingen doctrine may void it entirely.

The Evidence Clock: Why You Must Act Within 7 Days
The clock isn’t running tomorrow. It’s running right now. In City of Liverpool, your child’s case is decided by what gets preserved this week.
Park risk-management teams are already working while you are in the waiting room. They know their DVR systems will overwrite that Saturday afternoon in 7 to 30 days. They know the waiver kiosk database might purge version history in 72 hours. They know that by the time you hire a lawyer three months from now, the attendant who didn’t call 911 will have transferred to another location.
We don’t wait. We send forensic digital examiners to acquisition the NVR hard drives. We pull the incident-report metadata to see if it was “revised” after the fact. We use tools like Magnet AXIOM and Cellebrite to recover what the park tries to hide.

Catastrophic Pediatric Injuries: The Medical Reality
A “broken leg” at age eight is not just a broken leg. It is a potential life-altering event. Pediatric bone is biomechanically distinct. It is more pliable and contains an open physis, or growth plate.
- Salter-Harris Type II Fractures: These affect the growth plate. If not monitored for years, they can cause limb-length discrepancies or angular deformities that don’t manifest until your child hits a growth spurt at age 14.
- SCIWORA (Spinal Cord Injury Without Radiographic Abnormality): A child can sustain a permanent spinal injury even when the X-ray looks normal. The ligamentous laxity of a child’s neck allows the cord to stretch and bruise without breaking the bone.
- Vertebral Artery Dissection: As seen in the Elle Yona case that went viral on TikTok, a backflip into a foam pit can tear the artery in the neck, causing a spinal-cord stroke. These are often misdiagnosed as panic attacks in the ER.
We understand the medicine because we litigate it every day. Our active $10 million UH hazing case involves rhabdomyolysis and acute kidney failure. We know the CK levels, the myoglobin cascade, and the nephrology experts needed to document these catastrophic muscle-breakdown injuries that follow extended jumping.
You signed the waiver because you wanted your child to have fun. None of that put them in that hospital bed. The park’s business decisions did. Call 1-888-ATTY-911.
Adjacent Attractions: The New Danger Sector
Trampoline parks serving City of Liverpool aren’t just trampolines anymore. They are “Family Entertainment Centers” bolting on high-risk attractions like:
- Sky Rider Ziplines: These have a documented chain-wide strangulation pattern at Urban Air locations in Georgia, Illinois, and Florida.
- Harness Climbing Walls: The Matthew Lu fatality at Altitude Gastonia occurred because an employee failed to secure a harness. The park publicly admitted “human error” and removed the attraction—an admission-grade remedial measure.
- Electric Go-Karts: The 2025 death of six-year-old Emma Riddle in Florida involved a mechanical kart failure.
The trampoline waiver often fails to cover these non-trampoline attractions. We plead these separately, identifying the specific manufacturers like Ropes Courses, Inc. or UA Attractions, LLC.
Frequently Asked Questions for City of Liverpool Families
Can I sue if I signed the electronic waiver at the kiosk?
Yes. In Texas, a waiver is not a wall. We attack them for lack of conspicuousness, gross negligence, and the fact that parents cannot waive a minor’s right to sue under Munoz v. II Jaz. If the park’s surveillance video “glitched” simultaneously on four cameras, like the Mathew Knight case in Georgia, we move for spoliation sanctions.
How much money can my family get for a trampoline injury settlement?
Every case is unique, but successful outcomes range from $500,000 for severe fractures with growth plate damage up to $15 million or more for permanent spinal cord injuries. We build a Pediatric Life-Care Plan that forecasts your child’s needs for the next 70 years, not just the current hospital bill.
Is the foam pit really safer than just the trampoline?
No. Biomechanical studies by experts like Eager (2012) show that foam pits can be deadlier than beds when the foam is compressed or shallow. This is why many chains are replacing them with airbags. A park in City of Liverpool that still uses a deep foam pit is using 1990s technology for a 2026 risk.
What should I do if my child has dark urine after jumping?
Go to the hospital immediately. Dark, cola-colored urine is a sign of myoglobinuria, a hallmark of rhabdomyolysis. If your child was jumping for over an hour in a hot facility, their muscles may be breaking down. Tell the ER to check their CK levels. Then call us. We know this medicine better than any firm in Texas.
Why won’t the park give me the incident report?
They aren’t required to by law before a suit is filed, but our spoliation letter stops them from editing it. We often find that the “final” report they produce in discovery was revised several times to remove admissions of monitor inattention.
How long do I have to file a claim in Texas?
You generally have two years for an adult injury. For a child, the statute is tolled until they turn 18, meaning they have until age 20. But the evidence dies in 30 days. Waiting is the biggest mistake a family can make.
Does it cost anything to hire Attorney911?
No upfront costs. We advance the fees for biomechanical engineers, pediatric surgeons, and ASTM experts. We only get paid if we win your case.
Why Choose Attorney911 for a City of Liverpool Case?
We represent families, not files. When you call, you speak to an attorney with the federal-court experience and Fortune 500 litigation background required to take on the PE-backed conglomerates.
As client Donald Wilcox said, “One company said they would not accept my case. Then I got a call from Manginello… I got a call to come pick up this handsome check.” Other firms turn down these cases because they are afraid of the waiver. Our team includes the lawyer who used to write those waivers. We aren’t afraid of them.
We’ve gone toe-to-toe with Walmart, Amazon, FedEx, and UPS. The fleet of lawyers hired by Sky Zone, Inc. or Unleashed Brands doesn’t intimidate us. We’ve already fought that fight at the BP Texas City refinery and and in major medical-malpractice arenas.
What happened to your child at City of Liverpool wasn’t an accident—it was the predictable output of a system. The AAP has been warning about trampolines since 1999. ASTM F2970 was written by the trampoline park industry itself to establish a safety floor. The park operated below that floor to hit a margin target. The waiver was drafted by corporate counsel who knew it wouldn’t hold in most states. The surveillance is engineered to overwrite before most families have a lawyer.
We were built for exactly this fight.
Your child’s case is decided by what gets preserved this week. The DVR overwrites in 7 to 30 days. The waiver kiosk database purges. The attendant transfers. The foam pit refills. The incident report gets “revised.”
