One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park in Grand Prairie.
At the Big Air Trampoline Park or the nearby Urban Air and Altitude locations serving Grand Prairie families, a child can go from a Saturday afternoon birthday party to a pediatric trauma bay in less than three seconds. Their parents signed a waiver at a flickering kiosk twenty minutes earlier, usually under the pressure of a long line and excited kids. Now, as they sit in the waiting room at Children’s Medical Center Dallas or Cook Children’s in Fort Worth, they are told their child has a Salter-Harris growth plate fracture or, worse, a cervical spine injury that the ER staff is screening for SCIWORA—spinal cord injury without radiographic abnormality.
When that happens, the park’s management doesn’t usually call 911. They hand you a clipboard. They tell you it was a “freak accident.” They remind you that you “assumed the risk.”
They are wrong.
At Attorney911, we have spent more than 25 years making corporate defendants pay for the “business decisions” they disguise as accidents. Our founder, Ralph Manginello, has taken on Fortune 500 giants like BP in the wake of the Texas City refinery explosion and is currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis—the same catastrophic muscle breakdown we see in children who jump to the point of exhaustion in overheated Texas jump centers.
If your child was injured in Grand Prairie, you don’t need a generalist. You need a team that knows why the industry wrote ASTM F2970 to protect itself and how to use that same standard to prove the park was grossly negligent. You need Lupe Peña, our associate attorney who used to represent the insurance companies and recreational facilities you are now fighting. He knows the playbook they are using against you because he helped write it. Now, he uses that insider knowledge to dismantle their waivers and access the multi-million dollar insurance towers they try to hide.
What happened to your family wasn’t bad luck. It was the predictable output of a multi-billion dollar industry that puts margin ahead of pediatric safety. Call us at 1-888-ATTY-911. Hablamos Español. The case starts today.
What Grand Prairie Parents Need to Know: This Was Never an Accident
A trampoline injury is almost never an “accident” in the legal sense. In the eyes of the law, it is the result of a series of conscious business decisions.
Across Grand Prairie, from the neighborhood backyards in Westchester to the commercial courts near SH 161 and I-20, injuries are mounting. According to the Consumer Product Safety Commission (CPSC), approximately 300,000 trampoline-related emergency room visits happen every year in the United States. The vast majority of those victims are children.
For twenty-five years, the Americans Academy of Pediatrics (AAP) has been sounding the alarm. Since their landmark 1999 policy statement, reaffirmed in 2012 and 2019, the medical consensus has been clear: trampolines are not for recreational use, and they certainly do not belong in backyards or unregulated for-profit parks.
Every major chain—Sky Zone, Urban Air, Altitude, DEFY, and Big Air—knows this. They also know about ASTM F2970, the safety standard the trampoline park industry wrote about itself to establish a “safety floor.” When a park in Grand Prairie violates those standards—by understaffing a court, failing to separate age groups, or letting a foam pit compact until it’s like landing on the SH 161 shoulder—they aren’t just being sloppy. They are choosing to operate below the industry’s own minimum requirements to save on labor and maintenance costs.
The Grand Prairie Landscape: Saturated Risk
Grand Prairie families live in one of the most saturated trampoline park markets in the world. With Urban Air headquartered in nearby Grapevine and Altitude in Fort Worth, our region serves as the testing ground for these corporate giants.
- Big Air Trampoline Park (Grand Prairie): Located right off the George Bush Turnpike, this facility sees massive weekend traffic.
- Urban Air (Arlington/Mansfield/Southlake): Just minutes away, these parks often anchor weekend birthday party schedules for Grand Prairie ISDs.
- Altitude (Cedar Hill/Fort Worth): Frequently used for group events and “toddler time” sessions.
When thousands of children are airborne in the DFW metroplex on a Saturday, the law of large numbers dictates that injuries will happen. But the severity of those injuries is dictated by how the park is run. In Harris County, a jury returned an $11.485 million verdict against Cosmic Jump—the largest reported trampoline verdict in U.S. history—because the park knew a trampoline slide was torn and failed to fix it. A sixteen-year-old fell through a hole onto a concrete floor. The waiver was signed. The jury didn’t care. They found gross negligence.
That is the standard we hold parks to in Grand Prairie.
The Physics of the Injury: Why Children Suffer the Most
If you’ve seen your child get hurt on a trampoline, you likely saw the “double-bounce.” In the world of trampoline physics, this is a known energy-transfer mechanism.
When a 200-pound adult lands on a trampoline bed at the same time a 60-pound child is pushing off, the kinetic energy stored in the mat doesn’t just dissipate. It transfers. This can multiply the child’s launch force by up to four times. The child isn’t jumping anymore; they have been converted into a projectile.
Pediatric Biomechanics vs. Adult Reality
Children’s bodies are not just smaller versions of adult bodies. They are biomechanically distinct:
- Growth Plates (Physes): These are areas of active new bone growth. They are made of cartilage and are much weaker than the surrounding bone or ligaments.
- Developing Spines: A child’s cervical spine has more ligamentous laxity. This allows for more movement, which can lead to SCIWORA—where the spinal cord is stretched or compressed enough to cause paralysis even if the X-ray looks “normal.”
- The Physics of the Progam: Parks market “Toddler Time,” but ASTM F381 and the AAP explicitly state children under 6 should not be on trampolines. Their bones are not fully ossified, and their proprioception isn’t developed enough to handle the rebound forces of a commercial park.
When a Grand Prairie park ignores age-separation rules and lets a teenager jump next to a toddler, they are gambling with a child’s mobility. We use biomechanical engineers to model these impacts and prove that the force exerted on your child’s bone exceeded its break point because of the park’s failure to supervise.
Safety Standards: The Industry’s Own Admissions
The defense lawyers for parks like Sky Zone and Urban Air will try to tell you that there are no “laws” governing trampoline parks in Texas. They want you to believe that in the absence of a state inspector, they can do whatever they want.
They are half-right. Texas does not have a comprehensive state regulation for trampoline decks under Texas Occupations Code Chapter 2151. While the Texas Department of Insurance (TDI) regulates “Class B” inflatables—like the bungee trampolines and Sky Rider ziplines inside the parks—the trampoline courts themselves are largely self-regulated.
However, “self-regulated” does not mean “unregulated.”
We hold every park in Grand Prairie to ASTM F2970. This is the standard written by the industry itself. It requires:
- Attendant-to-jumper ratios: Usually one monitor per 32 jumpers, though higher-risk zones require more.
- Age and weight separation: Keeping the 200-pound linebacker away from the 40-pound kindergartner.
- Foam pit maintenance: ASTM requires specific depths (typically 42 inches of fill) and regular rotation of cubes.
- Daily inspections: Parks must document every morning that the mats aren’t torn and the spring padding is secure.
If the park’s own inspection log from three days before your child’s injury shows a torn mat that wasn’t replaced, that is subjective awareness of a risk. That is the bridge to punitive damages. We pair our ASTM mastery with EN ISO 23659:2022, the international mandatory standard the rest of the developed world uses. We show the jury that what Grand Prairie parks call “safe” would be illegal in Europe.

The 5-Layer Shield: Who We Really Sue
When you see a sign for “Urban Air” or “Sky Zone,” you are looking at a brand, not a target. The corporate structures of these chains are engineered to isolate liability and protect the “deep pockets” from the families they injure.
Our corporate archeology protocol strips away these layers:
- The Operator LLC: This is the local entity that signed the lease for the Grand Prairie or Arlington location. They are often undercapitalized and have the smallest insurance policy.
- The Franchisee: A multi-unit group that may own ten or twenty parks. They have deeper insurance layers.
- The Franchisor: Entities like UATP Management LLC or Sky Zone Franchising LLC. They dictate the “brand standards”—the training manuals and safety rules. If they failed to audit the local park, they are liable for their own independent negligence.
- The Parent Corporation: Sky Zone, Inc. (formerly CircusTrix) is parent to Sky Zone, DEFY, and Rockin’ Jump. Unleashed Brands (backed by Seidler Equity) owns Urban Air.
- The Private Equity Sponsor: Firms like Palladium Equity Partners. We have litigated against Fortune 500 companies and multinational corporations after the BP Texas City explosion. We know how to follow the money from a Grand Prairie trampoline court to a boardroom in New York or California.
In the case of Damion Collins v. Urban Air, an arbitrator in 2023 awarded $15.6 million for a paralysis injury. The franchisor—UATP Management—was forced to pay 40% of that award. This case proved that the “we’re just the brand licensor” defense is dead. We use this precedent to go after the entities that actually have the money to pay for a lifetime of medical care.
Common Accident Mechanisms in Grand Prairie Parks
If you are reading this, you are likely trying to understand exactly how your child’s injury happened. These are the most common ways Grand Prairie families are hurt:
1. The Foam Pit Failure
Foam pits look like piles of soft marshmallows. In reality, they are one of the most dangerous attractions in the building. As children jump into them all day, the foam cubes compress and shred. High-traffic parks often fail to “fluff” or rotate the foam. When your child lands, they sink through the compressed cubes and strike the concrete floor or a dense pad below.
- The Result: Cervical spine fractures or “trampoline fractures” (proximal tibial metaphyseal buckle fractures).
- The Standard: Violation of ASTM F2970 pit depth specifications.
2. The Un-Enforced Rule
Texas parks often have signs saying “No Flips” or “One Jumper Per Square.” Then, during a crowded Saturday afternoon, they have one sixteen-year-old monitor watching sixty kids. The monitor is on their phone or chatting with a co-worker. The “rules” exist only to give the park a defense in court; they have no intention of enforcing them if it slows down ticket sales.
- The Result: Head-to-head collisions and spinal injuries.
- The Standard: Violation of ASTM F2970 attendant training and supervision provisions.
3. The Harness and Zipline Failure
Urban Air’s “Sky Rider” and Altitude’s climbing walls are becoming more popular than the trampolines. But these involve mechanical systems. In Gastonia, NC, 12-year-old Matthew Lu fell 20 feet to his death because an employee failed to properly secure his harness. The park publicly admitted “human error” and removed the attraction. In Port St. Lucie, 6-year-old Emma Riddle died on an Urban Air go-kart just last year.
- The Result: Fatal head trauma or internal organ ruptures.
- The Standard: Negligent operation of a Class B amusement ride under Texas law.
4. Extended-Jumping Rhabdomyolysis
This is the hidden emergency. Grand Prairie’s summer humidity and heat create a dangerous environment for child athletes. A child who jumps for two hours straight without proper hydration can suffer muscle breakdown so severe that it releases myoglobin into their bloodstream.
- The Result: Acute kidney failure 12-48 hours after the jump session.
- The UH Bridge: We are currently litigating a $10 million lawsuit for rhabdo. We know how to document the “cola-colored urine” and elevated CK levels that prove the park’s environment was toxic to your child’s organs.
The Waiver Defense: Why You Shouldn’t Believe the Adjuster
Within 48 hours of your child’s injury, a claims adjuster will call you. They will sound concerned. They will say they want to “help out” with your initial hospital bill. They will then casually mention the electronic waiver you signed, implying you have no right to sue.
This is the Recorded Statement Trap. They are looking for you to say “I was watching him, but I looked away for a second” so they can shift 100% of the fault to you.
How We Break the Waiver in Texas
Texas law, while generally business-friendly, provides several “attack vectors” against trampoline park waivers:
- The Munoz Rule: Texas courts have held for thirty years that a parent cannot sign away a minor child’s right to sue for personal injuries. Your signature might bar your claim for medical bills, but it does not bar your child’s claim for their own pain, suffering, and permanent impairment.
- The Dresser Fair Notice Doctrine: A waiver in Texas must be “conspicuous.” If the release of negligence was buried in the fine print of a twenty-page click-through on an iPad, it fails the test.
- The Gross Negligence Carve-Out: You cannot waive gross negligence. If we can prove the park knew the court was dangerously overcrowded or the equipment was broken and they let your child jump anyway, the waiver is a scrap of paper.
- The Bilingual formation Defeat: Using the Delfingen doctrine, we argue that if your primary language is Spanish and the park only provided an English waiver at a rushed kiosk, there was no “meeting of the minds.” Contract formation failed. Lupe Peña uses this to protect Grand Prairie’s largest demographic.
48-hour Evidence Preservation: The Clock is Running
Evidence in Grand Prairie trampoline parks disappears on a schedule designed by corporate lawyers.
- Surveillance DVRs: Most parks in the DFW area overwrite their security footage every 7 to 30 days. If you don’t have a lawyer send a formal spoliation letter within the first week, the video of the attendant on their phone during your child’s fall will be gone forever.
- Waiver Metadata: Kiosk systems purge data on rolling cycles. We need the metadata to see exactly how many seconds you were given to read the “agreement.”
- Incident Reports: Parks have been known to “revise” incident reports days after the event. We subpoena the original handwritten draft—the one where the employee told the truth before the manager told them to change it.
Our firm sends a comprehensive litigation-hold demand within 24 hours of being retained. We demand the DVR hard drive, the training files, and the maintenance logs. We move faster than their risk-management team.
Catastrophic Pediatric Injuries: Beyond the ER Bill
When your child has a “broken leg” at the trampoline park, the medical bills you see now are just the beginning.
The Salter-Harris Growth Plate Reality
If the break was near a joint, your child likely has a Salter-Harris fracture. These injuries are a “silent catastrophe.” The bone might heal this month, but because the growth plate is damaged, that leg might stop growing while the other continues. You won’t know the full extent of the damage until your child hits their next growth spurt at age 12 or 14.
At that point, your child may need:
- Corrective osteotomy (surgically breaking and resetting the bone).
- Epiphysiodesis (intentionally stopping growth in the healthy leg to equalize length).
- LIFETIME biomechanical monitoring.
We don’t settle for “ER bills + $5,000.” We retain Certified Life Care Planners and pediatric orthopedic specialists to build a 50-year projection of your child’s needs. We account for the educational accommodations they’ll need after a TBI and the lost earning capacity they’ll face as an adult because of permanent mobility issues.
Why Hire Attorney911? The Moat of Authority
Grand Prairie families have dozens of options for personal injury lawyers. Most are “settlement mills” that handle car accidents and slip-and-falls. They “dabble” in trampoline cases.
We don’t dabble. We’ve built a practice around this accountability.
- We know the medicine: Our pending $10M rhabdo case against the University of Houston has made us experts in muscle-crush physiology.
- We know the defense: Lupe Peña used to sit on the other side of the table. He knows which insurance adjusters have the authority to write seven-figure checks and which ones are just stalling.
- We know the corporate structure: We’ve sued groups like Walmart, Amazon, and BP. We aren’t intimidated by a private-equity-backed park parent in a Tarrant County courtroom.
- We handle the expenses: We advance every dollar for the biomechanist, the digital forensic expert who recovers the “lost” video, and the surgeons who will testify. If we don’t win, you don’t pay us back.
Testimonials from Families Who Trust Us
“One company said they would not accept my case,” says our client Donald Wilcox. “Then I got a call from Manginello… I got a call to come pick up this handsome check.”
As Chad Harris says: “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.” When you are at the bedside of an injured child, being treated like family is the bare minimum you should expect.
Frequently Asked Questions for Grand Prairie Families
Can I sue if I signed the waiver?
Yes. As discussed, Texas law (Munoz) and the gross-negligence carve-out mean the waiver is almost never an absolute bar to recovery for a child.
How long do I have to sue a trampoline park in Texas?
The legal statute of limitations for personal injury is two years, but it is tolled for minors until their 18th birthday. However, you have less than 30 days to preserve the video evidence. Calling at year one is often too late to win the case.
Does it matter that I wasn’t the one who signed the waiver?
Often, yes. If a grandparent, a babysitter, or a friend’s parent signed for your child at a birthday party, they had no legal authority to bind your child to an arbitration agreement or a liability release. This is a common way we defeat the waiver entirely.
Will the park’s insurance pay my medical bills as they come in?
No. Insurance companies do not pay progressively. They pay one lump sum at the end of the case in exchange for a full release of liability. We help you manage those bills and negotiate with providers to treat your child now on a protected “lien” basis.
What is my trampoline injury case worth?
It depends on the permanency of the injury. A straightforward fracture might settle in the $75k-$250k range. A growth plate injury with permanent deformity anchors in the $500k-$2M range. Catastrophic spinal cord injuries resulting in paralysis have reached the $5M-$25M range nationally.
