In a quiet neighborhood off Spencer Highway or near the shaded streets of Fairmont Park here in La Porte, the sound of a spring-loaded mat and the laughter of children is a staple of Texas suburbia. Many families in our community choose the backyard trampoline as a way to burn energy during those humid Gulf Coast afternoons. Others make the short drive up Highway 146 to the massive indoor adventure hubs like Sky Zone in Baytown, Urban Air in Pasadena, or Altitude in Webster.
But we have seen how quickly that laughter turns into a sound no parent ever forgets. At The Manginello Law Firm—known to the families we represent as Attorney911—we know that sound because we have stood at the bedsides of children in trauma centers from Texas Children’s Hospital to Children’s Memorial Hermann. We have heard what Kati Hill, a mother whose son Colton’s femur was shattered at a park, called “the worst scream that you could ever have heard from a child.”
You are likely reading this at 11 PM in a hospital waiting room or on your couch after a long, quiet drive home from the emergency room. You are dealing with a mixture of terror, confusion, and a crushing sense of guilt. You signed a waiver at a kiosk. You let your child jump because you wanted them to have fun.
The first thing we need to tell you is this: None of this is your fault.
What happened to your child wasn’t a “freak accident.” It was the predictable output of a system designed to maximize profit while minimizing safety. The park’s insurance adjuster will tell you the waiver you signed ends your case. They are wrong. For over 25 years, our founder Ralph Manginello has gone head-to-head with some of the largest corporations in the world, including BP after the Texas City refinery explosion and multinational giants like Walmart and Amazon. We know their playbook. We know their tactics. And we know exactly how to hold them accountable.
The Reality of Trampoline Injuries in La Porte and Beyond
Whether the injury happened in a backyard in La Porte or at a commercial park in the surrounding Houston metro, the physics are the same. Nationally, more than 300,000 trampoline-related ER visits occur every year. In a medical radiographic essay published in 2024 by the American Journal of Roentgenology (AJR), researchers found that up to 1.6% of all pediatric emergency department trauma visits are now trampoline-related.
This is not a small, obscure risk. It is a documented pediatric trauma category. At Attorney911, we have spent two decades building the medical and legal architecture to fight these cases. Our firm includes a former insurance defense attorney, Lupe Peña, who used to draft and defend the very waiver clauses these parks rely on. Now, he uses that insider knowledge to dismantle them. We aren’t a generalist firm that “also” handles trampoline cases. We are the firm that knows the industry better than the operators do.
One Jump. One Landing. One Business Decision.
When a child is injured by a “double-bounce”—where a heavier jumper lands at the same time a lighter child is pushing off—the force of impact can be multiplied by up to 4x. This isn’t just an “inherent risk.” The trampoline park industry itself wrote a safety standard called ASTM F2970 to prevent exactly this.
ASTM F2970 requires parks to enforce age and weight separation. When a park ignores that rule to pack more people onto the court on a Saturday afternoon, they are making a business decision to accept the risk of your child’s injury in exchange for a higher margin. We don’t view these as accidents. We view them as breaches of a duty the park admitted they held when they signed their franchise agreement.
The “Paper Shield”: Why Your Waiver Does Not End Your Case
The most common question we hear from parents in La Porte is: “But I signed the waiver, so I can’t sue, right?”
In Texas, the answer is often no. Our state follows specialized doctrines that protect children even when a parent has signed a click-through agreement on an iPad. Under the landmark Texas case Munoz v. II Jaz, Inc., courts have held that a parent generally cannot sign away a minor child’s personal injury cause of action in advance. Your child did not sign that waiver. Your child did not consent to have their growth plate destroyed or their spine compressed.
Furthermore, Texas applies the Dresser Industries v. Page Petroleum “fair notice” doctrine. For a waiver to be enforceable against an adult in Texas, it must be conspicuous—bold, large, or clearly set apart—and it must meet the “express negligence” rule. If the waiver didn’t specifically and clearly say it was releasing the operator’s own negligence, it may be a legal nullity.
The Cosmic Jump Precedent: $11.485 Million
You don’t have to look far to see how these cases end when a skilled legal team takes the floor. 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 trampoline mat onto concrete. The waiver was signed. The park argued the risk was assumed. The jury found gross negligence anyway.
That is the largest reported jury verdict against a US commercial trampoline park, and it happened right here in our backyard. It is the gold standard for how we build our cases: by proving that the park had actual knowledge of a hazard and showed conscious indifference to the safety of your child.
Hidden Dangers of Multi-Attraction Parks
The modern “trampoline park” in the Houston area has pivoted. Chains like Sky Zone (now owned by Palladium Equity Partners) and Urban Air (owned by Seidler Equity Partners under the Unleashed Brands umbrella) have bolted on increasingly dangerous attractions to maintain their competitive edge.
If your injury happened at one of these adjacent attractions, the legal landscape shifts:
- Sky Rider & Indoor Coasters: We have seen a documented chain-wide pattern of Sky Rider zipline strangulations and falls at Urban Air locations from Newnan, Georgia to North Jersey.
- Climbing Walls Over Concrete: In 2019, at an Altitude Trampoline Park in Gastonia, Matthew Lu was killed because employees failed to secure his harness correctly, and he fell 20 feet onto concrete. The park later admitted “human error” and removed the wall entirely.
- Go-Kart Malfunctions: On December 6, 2025, six-year-old Emma Riddle was killed at an Urban Air in Florida when her go-kart reportedly surged forward despite her mother not pressing the accelerator.
In every one of these cases, we look at the corporate archeology. We don’t just sue the local LLC. We go upstream to the franchisor and the private equity sponsor. We find the money where it is hidden because the local operator is almost always undercapitalized with a policy limit that won’t cover a catastrophic injury.
Catastrophic Pediatric Injuries: The Medicine We Master
A trampoline injury to a child is not “a broken bone.” It is a disruption of a developing life. At Attorney911, we use a level of medical specificity that makes insurance adjusters realize we cannot be ignored.
Salter-Harris Growth Plate Fractures
When a child’s growth plate is fractured, the damage may not fully manifest for years. A Salter-Harris Type II fracture at age eight can produce a limb-length discrepancy that doesn’t become visible until the child hits a growth spurt at age fourteen. By then, the “quick settlement” the park offered you is long gone. We retain pediatric orthopedic surgeons to project your child’s needs through skeletal maturity.
SCIWORA: The Invisible Spinal Injury
Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) is a pediatric-specific danger. A child can enter a foam pit head-first and suffer a devastating cord injury even when the initial CT scan in the ER looks normal. Because children’s spines are flexible, the cord can be stretched or compressed even when the bones don’t break. If your child was told they just had “neck stiffness” but their symptoms are worsening, they need a specialist.
The Rhabdo Bridge: A Signature Firm Edge
We currently litigate a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. This is the exact same injury pathology we see when children jump for ninety minutes in a hot indoor park without adequate hydration. The muscle tissue breaks down, spilling myoglobin into the blood and poisoning the kidneys. Most ERs miss this diagnosis on the first visit. Because we are litigating a major rhabdo case right now, we have the medical experts and the institutional-accountability playbook to win these cases for trampoline victims.
The Evidence Clock: Why the Next 7 Days Are Vital
In La Porte, the statute of limitations gives you time to file a lawsuit, but the evidence clock is running right now.
- Surveillance Overwrite: Most parks in the Houston area, including Sky Zone and Urban Air, use DVR systems that overwrite old footage every 7 to 30 days. If we don’t send a formal spoliation letter this week, the video of your child’s impact is gone forever.
- Waiver Purges: Kiosk databases often purge specific version histories on 72-hour rolling cycles. We capture these versions using Wayback Machine forensics before the park “updates” its system to retrofit missing safety language.
- Staff Turnover: Trampoline park attendants are often teenagers with a 130-150% annual turnover rate. We find these witnesses—the “insiders”—before they move to their next job.
Our associate attorney Lupe Peña knows exactly which documents to target because he used to defend these cases. We don’t wait for discovery. We demand the 911 CAD records, the attendant time-clock logs, and the daily pre-opening inspection logs within 24 hours of being retained.
Frequently Asked Questions for La Porte Families
Can I sue if the waiver was only in English but I speak Spanish?
Sí. Under the Texas Delfingen doctrine, a contract signed when the patron could not understand the language may be challenged for lack of valid formation. If a teenage attendant at an Urban Air or Altitude park pressured your Spanish-speaking family to “sign quickly so the kids can jump” without providing a translation, that waiver is extremely vulnerable. Lupe Peña speaks with our Spanish-speaking clients directly—no interpreters, no delays.
How much is my child’s trampoline injury case worth?
The value depends on the injury severity and the insurance layers available. While smaller fracture cases may settle in the $50,000 to $500,000 range, catastrophic cases involving TBI, spinal cord injury, or permanent disability reach into the millions. The Damion Collins v. Urban Air award of $15.6 million proves that when systemic failures are documented, the numbers reflect the lifelong cost of care.
The park manager said it was a “freak accident.” Does that matter?
No. An incident report is the park’s self-serving narrative, not a legal conclusion. Our biomechanical engineers reconstruct the impact to prove it was a predictable result of violating industry standards like ASTM F2970.
What if my child was a guest at a birthday party and I didn’t sign the waiver?
This is one of our strongest “waiver gap” exploits. If a party host signed a master agreement but you never signed a specific waiver for your child, the park has no waiver defense against you at all. We check the check-in logs and kiosk metadata on day one to find these loopholes.

La Porte Area Backyard Trampoline Safety Note
If your injury happened in a backyard here in La Porte, the Gulf Coast humidity can be a silent killer. Salt air and 90% humidity corrode spring coils and degrade polypropylene netting twice as fast as inland climates. A five-year-old net in La Porte often has zero tensile strength remaining under UV exposure. If a component failed, we pursue the manufacturer under strict product liability. If a neighbor’s trampoline was unsecured, the “attractive nuisance” doctrine protects your child.
Detailed Liability Analysis: The 5-Layer Corporate Stack
When we investigate a park like Sky Zone or Urban Air, we look at the entire corporate archeology:
- Operator LLC: The local entity in Pasadena or Baytown.
- Franchisee: The multi-unit owner who may own five or ten locations.
- Franchisor: Sky Zone Franchising LLC or Urban Air Franchise Holdings.
- Brand Parent: Sky Zone, Inc. (f/k/a CircusTrix) or Unleashed Brands.
- Private Equity Sponsor: Palladium Equity Partners or Seidler Equity Partners.
We go upstream because that is where the margin-cutting decisions are made, and that is where the $50M+ insurance towers live.
Frequently Asked Questions (Enhanced)
What if the park’s video “glitched” during the accident?
We consider this fraud-grade conduct. In a Georgia case (Mathew Knight), a jury awarded $3.5 million after video from four cameras “glitched” at the exact moment of the injury. We retain digital forensic examiners to image the DVR and find out who deleted the footage.
Is the “Glow Night” more dangerous?
Yes. Lawsuits have repeatedly pointed to “Glow in the Dark” events with reduced lighting as contributing factors. Monitors cannot see collisions in near-darkness, and the lack of depth perception leads to catastrophic mis-landings.
What is a “Life Care Plan”?
For a child with a permanent injury, we prepare a Life Care Plan that forecasts every medical cost for the next 70 years—wheelchair replacements, revision surgeries, physical therapy, and home modifications. We don’t settle for the ER bill; we settle for the child’s entire future.
