#”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.”
Those are the words of Kati Hill, the mother of three-year-old Colton, describing the moment a family outing at a trampoline park turned into a nightmare. Her son Colton spent months in a body cast because a heavier jumper was allowed on the same trampoline bed. For families in Oyster Creek, these stories often feel far away until the moment they aren’t—until a birthday party at a park in nearby Pearland or Sugar Land ends with an ambulance ride to a Level 1 pediatric trauma center like Texas Children’s Hospital in the Houston Medical Center.
We have spent more than twenty-five years standing at the bedside of families just like yours. We are Attorney911, and our founder, Ralph Manginello, has spent his career holding corporate giants accountable. Since 1998, we have fought for families in the wake of catastrophic accidents, including those who have suffered traumatic brain injuries, spinal cord damage, and wrongful death.
If your child was injured on a trampoline in Oyster Creek, whether at a neighbor’s house on the creek or a commercial park along the I-45 or Highway 288 corridors, you are likely feeling a mix of terror, guilt, and confusion. You might have signed a waiver on an iPad at a kiosk. You might have been told that “accidents happen.”
We are here to tell you that a trampoline injury is never just an accident. It is almost always a business decision that went wrong. At the Manginello Law Firm, we don’t just “handle” personal injury cases; we dismantle the defenses used by national chains like Sky Zone, Urban Air, and Altitude. We know the industry standards, we know the biology of pediatric fractures, and we know exactly where the insurance money is hidden in a five-layer corporate stack.
The Reality of Trampoline Injuries in South Texas
Operating in the City of Oyster Creek means understanding the specific risks our local families face. We live in a climate defined by high humidity, salt air from the Gulf, and intense UV exposure. While a backyard trampoline from Jumpking or Skywalker might look sturdy, the Gulf Coast environment actively degrades polypropylene netting and rusts metal springs faster than almost anywhere else in the country.
But even more concerning than the backyard risk is the explosion of commercial trampoline parks across Brazoria and Harris Counties. Nationally, more than 300,000 trampoline-related ER visits occur annually. In a recent study published in Pediatrics (Teague et al., 2024), researchers tracked over 13,000 injuries and found that foam pits carry an injury rate of 1.91 per 1,000 jumper-hours. For families driving from Oyster Creek to the larger jump arenas in the metro, those statistics represent a very real daily hazard.
We represent the parents who were told by a teenage “court monitor” that their child was fine, only to discover hours later that the child had a Salter-Harris growth plate fracture. We represent families who signed waivers and now believe they have no rights. Our team includes attorney Lupe Peña, who previously worked as an insurance defense lawyer. He used to represent the very recreational businesses and insurers we now sue. He knows which waiver clauses are ironclad and which ones are full of holes. He knows the adjuster’s script because he helped write it.
If you are standing at a hospital bed right now, or if your child is facing a decade of orthopedic surgeries, don’t let a piece of paper you signed at a front desk stop you from seeking justice.
Call 1-888-ATTY-911. We answer 24/7. Hablamos Español. We work on a contingency fee basis, meaning we advance every cost—the biomechanical engineers, the pediatric surgeons, the accident reconstruction experts—and you owe us nothing unless we win.
Part I: The Industry Standard vs. The Reality at the Park
Most families believe that because a trampoline park is open for business, it must be inspected and regulated. In Texas, the truth is startling: we have no statewide trampoline park safety act. There is no state licensing, no mandatory inspections, and no required injury reporting for the trampoline decks themselves.
The Regulatory Gap in Texas
While the Texas Department of Insurance (TDI) regulates “Class B” inflatable rides like bungee trampolines or inflatable obstacle courses under Texas Occupations Code Chapter 2151, the state explicitly excludes the main trampoline beds. This leaves the safety of your child entirely in the hands of the operator’s own internal policies and the voluntary standards set by ASTM International.
We don’t just read ASTM F2970—the commercial safety standard for trampoline parks—we have it memorized. We know that F2970 requires specific attendant-to-jumper ratios and age-separated jumping zones. When we investigate a case in Brazoria County, we pull the park’s training logs and daily inspection sheets. We often find that the “standard of care” the park claims to follow is ignored the moment the Saturday afternoon rush hits.
The International Perspective
The United States is one of the few developed nations without a binding national safety standard for these facilities. In Europe, the EN ISO 23659:2022 standard is a mandatory requirement that covers design, construction, and operation. In Australia, they follow AS 4989:2015. Chains like Sky Zone and Urban Air often operate to a safety “floor” in America that the rest of the world treats as a dangerous ceiling.
We use this global gap to prove negligence. If a safer design or a more rigorous staffing protocol exists and is used by the same brands in other countries, your child deserves that same level of protection here in Texas.
Part II: The Physics of Peril — Why Children Get Hurt
Trampoline injuries aren’t caused by bad luck; they are caused by physics that neither children nor most attendants understand.
The Multi-Person Double-Bounce
The most common mechanism of catastrophic injury is the “double-bounce.” This occurs when two jumpers of different weights share the same bed. When a 200-pound adult lands while a 60-pound child from Oyster Creek is pushing off, the energy transfer multiplies the child’s launch force by up to four times.
The child isn’t just jumping anymore; they have become a projectile. This energy transfer hits the pediatric tibia or femur with roughly 1,000 Newtons of force—enough to snap a bone even without a fall. This is why ASTM F2970 and all reputable manufacturer instructions for use (IFUs) from brands like Springfree or ACON prohibit multiple jumpers. Yet, if you walk into any park on a busy Friday night, you will see monitors looking at their phones while weight-mismatched jumpers share the same bed.
The Foam Pit Illusion
Foam pits look like harmless clouds of polyurethane, but they are among the most dangerous areas of any park. When foam cubes aren’t rotated or replaced according to schedule, they compact. A jumper entering the pit head-first or feet-first can “bottom out,” striking the hard concrete floor beneath.
We cite the research of experts like Eager (2012), which documents the specific cervical hyperflexion and axial compression risks inherent in foam pits. The industry knows these risks; that is why many parks are switching to airbags. If your child was injured in a foam pit at a park that refused to upgrade to safer landing technology, we treat that as a conscious decision to prioritize profit over safety.
The Toddler Time Violation
The American Academy of Pediatrics (AAP) has been clear since 1999: children under age six should never use trampolines. This position was reaffirmed in 2012 and 2019. Despite this, parks actively market to toddlers. When a three-year-old’s bones—which are still largely cartilaginous and developing—are subjected to the high-G forces of a commercial trampoline mat, the results are often permanent.
We represent the Oyster Creek parents who trusted the “Toddler Time” branding, only to have their child suffer a “trampoline fracture”—a proximal tibial metaphysis buckle fracture—caused by the very activity the park claimed was safe for their age.
Part III: Corporate Archeology — Who Is Responsible?
When you sue a trampoline park, you aren’t just suing the local building. You are taking on a layered corporate structure designed to shield the real money from accountability. We call this “corporate archeology.”
The 5-Layer Defendant Stack
If your child is hurt at a Sky Zone, for instance, we identify every layer:
- The Operator LLC: The local entity running the building.
- The Franchisee: The multi-unit owner that may run several Texas locations.
- The Franchisor: Sky Zone Franchising LLC, which dictates the safety rules.
- The Parent Company: Sky Zone, Inc. (formerly CircusTrix), now parent to brands like DEFY and Rockin’ Jump.
- The Private Equity Sponsor: The deep pockets, like Palladium Equity Partners or Seidler Equity Partners (who acquired Urban Air’s parent, Unleashed Brands).
We pierces these shields. We don’t accept the “we are just a brand licensor” defense. We use the precedent from Collins v. Urban Air Overland Park, where an arbitrator awarded $15.6 million and held the franchisor responsible for 40% of the damages. The arbitrator found a “systemic failure” in training and safety implementation. That is the same pattern we look for in every Brazoria County case.
Product Liability: The Manufacturer and Retailer
In backyard cases, the liability often shifts to manufacturers like Jumpking or Skywalker. We look for manufacturing defects (failed welds), design defects (inadequate enclosures), and failures to warn. We also hold retailers like Walmart or Amazon accountable under strict product liability when they sell private-label trampolines—like the Bouncepro line—that they know are hazardous.
Contact us at 1-888-ATTY-911. The evidence at the park is disappearing every day. We need to send our spoliation letters now to freeze the surveillance video before it’s gone.
Part IV: Why Your Signed Waiver is Likely Void
The single most common thing parents say to us is, “I signed a waiver, so I don’t have a case.” That is exactly what the insurance companies want you to believe. In reality, the waiver is often just noise.
The Texas Minor Waiver Rule
In Texas, we have a very clear protection for our children. The landmark case Munoz v. II Jaz, Inc. (1993) established that, in most commercial contexts, a parent cannot sign away a minor child’s right to sue for personal injuries. Your signature might bar your own claims for medical bills, but it generally cannot kill your child’s direct cause of action.
Gross Negligence and the Cosmic Jump Precedent
Even for adults, a waiver does not protect a park from “gross negligence.” Under the Texas standard set in Moriel, gross negligence means the park was subjectively aware of an extreme risk and proceeded anyway with conscious indifference.
In Harris County, a jury awarded $11.485 million against Cosmic Jump because the park knew about a tear in a trampoline slide and failed to fix it or warn Max Menchaca before he fell through it to the concrete. The waiver was signed. It didn’t matter. When a park knowingly understaffs a court or leaves a defect unrepaired, they have stepped outside the protection of that waiver.
The Bilingual Formation Defeat
Many Oyster Creek families speak Spanish as their primary language. If you were presented with an English-only waiver on an iPad and pressured to sign it quickly so your kids could jump, that contract may be void. We use the Delfingen US-Texas v. Valenzuela (2013) doctrine to argue that there was no meaningful assent. Lupe Peña speaks with our Spanish-speaking clients directly, ensuring the language barrier doesn’t become a legal barrier.
Part V: Catastrophic Injuries and Medical Specificity
When we build a case, we don’t just say your child has a “broken leg.” We use the medical specificity that forces insurance adjusters to realize we are ready for trial.
- Salter-Harris Type II Fractures: This is a fracture through the growth plate of a pediatric bone. Because the growth plate produces new bone, an injury here can lead to permanent limb-length discrepancy or angular deformity. We work with pediatric orthopedic experts to project the twenty years of medical monitoring and potential corrective surgeries your child will need.
- SCIWORA (Spinal Cord Injury Without Radiographic Abnormality): This is a terrifying pediatric phenomenon where a child’s spine is torqued, causing permanent paralysis, even though the initial X-ray or CT scan looks normal. We know that in Oyster Creek, if a child lands head-first in a foam pit, a “clear” CT in the ER is not a diagnosis. We demand MRI imaging to check for cord ischemia.
- Diffuse Axonal Injury (DAI): These are TBIs caused by shearing forces in the brain during a collision or rapid deceleration. They often lead to cognitive regression, academic struggle, and personality changes that don’t manifest until months later. we ensure your child receives a full neuropsychological battery to document their developing brain’s actual condition.
The Rhabdomyolysis Bridge
One of the most under-reported emergencies at trampoline parks is exertional rhabdomyolysis. This occurs when a child jumps for 90 minutes straight in a hot, humid South Texas facility without adequate hydration. The muscle tissue breaks down, releasing myoglobin that can cause acute kidney failure.
We are currently litigating a $10 million lawsuit against the University of Houston involving rhabdo. The physiology is the same. If your child had “cola-colored” urine or rock-hard muscle pain a day after visiting a trampoline park, they need an ER immediately, and then they need a lawyer who understands the medical architecture of muscle-and-organ breakdown.
Part VI: The 48-Hour Evidence Preservation Protocol
The clock is not your friend. Trampoline park surveillance systems are typically set to overwrite footage every 7 to 30 days. If you wait for the hospital bills to arrive before calling a lawyer, the video of your child’s accident is likely gone.
When you retain our firm, we send a formal spoliation letter within 24 hours. We demand more than just the video. We demand:
- The Original Incident Report: Parks often “revise” these reports 48 hours later to sanitize the language. We subpoena the metadata to see what was changed.
- Waiver Metadata: We find out if the waiver version you signed was actually the one in effect that day.
- Staffing Records: We look at time-clocks to see if the attendants were overworked or under-trained. We check for child labor violations, similar to the $68,000 fine Sky Zone Tukwila paid for overworking its teenage staff.
- Daily Inspection Logs: We look for “pro forma” signatures—where the same attendant signed off on the same equipment for 30 straight days without actually looking at it.
Part VII: Determining the Value of Your Case
Families in Brazoria County deserve to know what a full recovery looks like. Damages in a catastrophic trampoline case aren’t just about the first six months; they are about the next sixty years.
Economic Damages
We build a Pediatric Life-Care Plan. This includes every cost from hardware removal surgeries to special education accommodations. For a child with a severe TBI, these costs can easily reach the $3M – $10M range. We also quantify lost earning capacity—what your child would have earned as an adult if their potential hadn’t been capped by a brain or spinal injury.
Non-Economic Damages
This is the human cost. The pain, the mental anguish, and the “loss of enjoyment of life.” When your son can no longer play soccer with his friends in Oyster Creek, or your daughter is terrified to go to a friend’s birthday party, that is a real loss that a jury can and should compensate.
Punitive Damages
In cases of gross negligence—like the Cosmic Jump case—Texas law allows for exemplary damages aimed at punishing the defendant and deterring others. When we prove a park ignored its own safety manual for months, we go for the “kill shot” that forces the corporate parent to pay attention.
Call 1-888-ATTY-911. We advanced all expert costs. From the biomechanist who reconstructs the energy transfer of the double-bounce to the life-care planner who projects your child’s lifetime needs, we have the resources to win.
Part VIII: Frequently Asked Questions for Oyster Creek Families
Can I sue if the attendant was just a teenager?
Yes. The fact that the park hired a 16-year-old with only two hours of training is actually evidence of their negligence. ASTM F2970 requires trained supervision. If the park put a child in charge of your child’s safety to save on labor costs, they are responsible for that decision.
The park manager said they wouldn’t call 911 because it wasn’t serious. Is that normal?
It’s a documented tactic. In a Southlake Urban Air Triadvisor review, a parent noted that management specifically instructed staff NOT to call 911. They want you to leave the building so their liability ends. If they refused to call emergency services, that is evidence of conscious indifference to your child’s health.
How do I pay my medical bills while the case is pending?
We help negotiate medical liens down by 20-40% at the end of the case. We also work with providers who treat on a lien basis—they provide the care now, and we ensure they are paid from the settlement. Your child’s recovery should never wait for an insurance check.
Does it matter if I don’t live in Houston?
We have offices in Houston, Austin, and Beaumont, but we handle trampoline cases throughout Texas and nationwide. Whether the accident happened in Pearland, Galveston, or outside the state, we travel to our clients. We associate with local counsel where required at no additional cost to you.
What if my child was injured on a neighbor’s trampoline?
This usually falls under the “Attractive Nuisance” doctrine. In Texas, if a homeowner has an artificial condition (like a trampoline) that they know will attract children, they have a duty to secure it. If your child wandered onto a neighbor’s trampoline in Oyster Creek and was hurt, the neighbor’s homeowners’ insurance is the primary target. We look for umbrella policies that can provide $1M-$5M in coverage even if the base policy has a trampoline exclusion.

The Evidence Disappearance Clock: Why Urgency is Non-Negotiable
If you take only one thing from this guide, let it be this: the evidence is already disappearing.
- 7 Days: Many park DVR systems begin rolling over their hardest-hit camera angles (the ones with high resolution) within a week.
- 30 Days: Most incident reports have been electronically “finalized,” making the first-draft admissions harder to find.
- 60 Days: The attendants who witnessed the accident—the high-turnover teenage staff—often have moved to different jobs.
We stop the clock. When we file a case, we don’t just ask for the documents; we use our 25 years of trial experience to demand the raw data, the software audit logs, and the franchisor’s own internal safety audits. We make sure the “surveillance glitch” that happened in a Georgia case (Mathew Knight $3.5M verdict) doesn’t happen to your family.
Final Word to Parents in Brazoria County
We know you’re in pain. We know you’re angry. What happened to your child at an Oyster Creek backyard or a Texas trampoline park was foreseeable, preventable, and a direct result of a company choosing profits over participants.
At the Manginello Law Firm, we believe in accountability. We believe those corporate conglomerates with $600M in annual sales should be the ones paying the price for a three-year-old’s body cast—not the family that just wanted to have fun on a Saturday afternoon.
We represent families. We represent children. We represent you.

FAQ: Trampoline Park Law in Texas
Q: Can I sue if I signed the waiver?
A: Yes. Texas law voids waivers for gross negligence and has strict fair-notice requirements. Furthermore, Munoz v. II Jaz protects the rights of minor children.
Q: How much does a trampoline park lawyer cost?
A: We work on a contingency fee. You pay $0 upfront. We advance all case expenses. We only get paid when we recover money for your child.
Q: How long do I have to sue a trampoline park in Texas?
A: The adult SOL is two years. For children, the statute of limitations is “tolled” until they turn 18, meaning they have until age 20. However, waiting that long is a mistake because the evidence will be long gone.
Q: Is the foam pit safe if it’s full of blocks?
A: Not necessarily. Cubes compact over time. Peer-reviewed research shows that foam pits are a leading cause of cervical spinal cord injuries when they aren’t maintained to the 6-foot depth industry standard.
What to Look for in Your Kiosk Waiver — The “Dresser” Checklist
Next time you’re at a park, look for these three things. If they’re missing, the waiver is likely unenforceable even for adults:
- The Word NEGLIGENCE: It must be stated explicitly.
- Conspicuous Formatting: The release can’t be in the same small font as the rest of the text.
- No Language Barriers: If you speak Spanish, they must provide a translation or give you time to understand it through your own resources.
Why the Franchisor is on the Hook
Don’t believe the park manager who says “we are just independent owners.” We use the Apparent Agency doctrine. Because Sky Zone or Urban Air controls the branding, the uniforms, the training, and the website, they are responsible for the safety of the facility. We go upstream to the $50M – $100M insurance towers that the franchisor and corporate parent carry.
