One Bad Landing in Royse City: The Parent’s Guide to Trampoline Injury Accountability

If you are reading this at 11 PM from a trauma-bay bedside or while your child is sleeping fitfully in a leg cast in your home in Royse City, there is something you need to hear before we discuss statutes, standards, or settlements: This is not your fault.

You signed the waiver because the line at the kiosk was long and the staff was rushing you. You let your child jump because you wanted them to have fun on a Saturday afternoon in Rockwall County. You trusted the park to follow the safety rules they advertised. The fact that those rules were ignored—that the attendant was on their phone, that the foam pit was compacted, or that an adult was allowed to double-bounce your child—is a business decision made by the operator. It is not a failure of your parenting.

At Attorney911, led by Ralph Manginello with over 25 years of catastrophic injury experience, we have spent decades making corporate defendants take responsibility for these kinds of “business decisions.” From litigating against multinational corporations like BP after the Texas City explosion to our current $10 million lawsuit against the University of Houston for rhabdomyolysis and kidney failure, we know the playbook the insurance companies use. We also know how to tear it apart.

If your family’s life changed in a heartbeat at a trampoline park near Royse City, the clock is already running. Not just the legal clock, but the evidence clock. Surveillance video in these facilities is often overwritten in as little as 7 to 30 days. Incident reports get “revised” on corporate servers. Our firm is built to move faster than the park’s risk management team.

The Reality of Trampoline Injuries in North Texas

Royse City is part of one of the fastest-growing regions in the United States. Families flock here for the schools in Royse City ISD and the community feel of Rockwall County. But with that growth has come a saturated market of “family entertainment centers.” When you hop on I-30 and head toward the Urban Air in Rockwall or the Jumping World in Garland, you are entering a facility where throughput is the primary metric of success.

On a typical Saturday, hundreds of children are airborne simultaneously. According to the CPSC’s National Electronic Injury Surveillance System (NEISS), trampolines send more than 300,000 Americans to the emergency room every year. A staggering 2024 study published in the journal Pediatrics by Teague et al. found that for every 1,000 hours of jumping in a commercial park, 1.14 injuries occur. In the foam pits, that rate jumps to 1.91 per 1,000 hours.

In a metro area the size of Dallas-Fort Worth, the Fort Worth Star-Telegram documented 500 injury reports across 21 trampoline parks over a seven-year period. In Royse City, those numbers aren’t just statistics; they represent shattered growth plates, traumatic brain injuries, and cervical spine fractures.

We don’t look at your child’s injury as “bad luck.” We look at it through the lens of ASTM F2970—the safety standard the trampoline park industry actually wrote about itself. When a park fails to maintain a 1:32 monitor-to-jumper ratio or ignores age-separation rules, they aren’t just being “careless.” They are violating their own industry floor to save on labor costs.

The $11.485 Million Precedent: Why the Waiver is Not a Wall

The most common reason parents hesitate to call an attorney is the “paper shield.” The park told you that because you signed a waiver on an iPad at the front desk, you have no case. In Texas, that is often a lie.

Consider the case of Max Menchaca. He was a 16-year-old in Harris County who fell through a tear in a trampoline slide at a park called Cosmic Jump. He hit the concrete floor beneath the mat and suffered a traumatic brain injury. Cosmic Jump pointed to the signed waiver. The jury looked at the evidence: the park knew the mat was torn and did nothing. That jury returned a verdict of $11.485 million, including $6 million in punitive damages.

The jury found gross negligence, and in Texas, no waiver in the world can release a company from gross negligence. Our associate attorney, Lupe Peña, used to sit on the other side of the table. He defended insurance companies and recreational businesses against these exact claims. He knows which clauses in those Royse City-area park waivers are full of holes. He knows which arguments Texas courts void and which ones insurance adjusters use just to scare you away.

The Physics of the Double-Bounce: A Catapult for Children

The mechanism that most frequently brings Royse City families to our door is the double-bounce. It happens in two seconds. A 200-pound adult lands on a trampoline mat at the same moment a 60-pound child is pushing off. Through a process called kinetic energy transfer, the child is launched with up to 4x their original force.

The child isn’t jumping anymore. They are a projectile.

Pediatric bone is biomechanically distinct from adult bone. It is more pliable, but it contains growth plates (physes) that are structurally weaker than the surrounding bone. When that child lands from a multiplied height, they often sustain a Salter-Harris fracture—an injury to the growth plate that can cause a leg to grow crooked or stop growing entirely.

The American Academy of Pediatrics (AAP) has been warning about this since 1999. They reaffirmed their position in 2012 and again in 2019: trampolines do not belong in the home, and recreational use at parks should be strictly segregated by size and age. When an Urban Air or a Sky Zone near Royse City allows a teenager and a toddler on the same court, they are inviting a catapult event.

The Corporate Stack: Who is Actually Responsible?

When we take a case in Royse City, we don’t just sue the local LLC listed on your receipt. We perform “corporate archaeology” to find where the money and the decision-making actually live. Most parks are engineered as a five-layer stack designed to hide assets:

  1. The Operator LLC: The local entity with the lease, often undercapitalized.
  2. The Franchisee: A larger group that may own several North Texas locations.
  3. The Franchisor: Corporate entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings.
  4. The Parent Corporation: Sky Zone, Inc. (formerly CircusTrix, backed by Palladium Equity Partners) or Unleashed Brands (parent of Urban Air, backed by Seidler Equity Partners).
  5. The Private Equity Sponsor: The deep pockets that approved the cost-cutting measures that led to your child’s injury.

We have gone head-to-head with some of the largest corporate defendants in the world. The parent conglomerates behind national trampoline chains hire the same high-priced defense firms we beat in the BP refinery litigation. They don’t intimidate us. We know that the franchisor often retains operational control over training and safety audits, which makes them just as liable as the 17-year-old “court monitor” who wasn’t watching the mat.

Catastrophic Injuries: Beyond the Emergency Room Bill

A trampoline injury in Royse City isn’t just an ER visit; it’s a lifetime trajectory change. We work with a network of experts to quantify the true cost of your child’s recovery.

Traumatic Brain Injury (TBI)

A head-first landing into a foam pit that was compacted below ASTM F2970 specifications can result in a Diffuse Axonal Injury (DAI)—the shearing of brain fibers. In a developing brain, the damage may not fully manifest for 6 to 18 months, showing up as academic regression or executive function failure.

Spinal Cord Injury and SCIWORA

Pediatric spines have significant ligamentous laxity. A child can suffer a spinal cord injury without a visible fracture on a CT scan—a condition known as SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). If the park staff or an undertrained ER doctor tells your child to “walk it off,” they may be extending cord ischemia that leads to permanent paralysis. We recently saw the viral case of Elle Yona, whose spinal cord stroke after a park backflip was initially misdiagnosed as a panic attack. We don’t accept misdiagnosis.

Rhabdomyolysis: The Under-Reported Emergency

If your child jumped for 90 minutes at a local park without a water break and arrives home with dark, “cola-colored” urine and rock-hard muscle pain, they are in a medical emergency. Exertional rhabdomyolysis—muscle breakdown that poisons the kidneys—is a documented risk of extended trampoline use.

Our active $10 million lawsuit against the University of Houston involves this exact pathology. We know the creatine kinase (CK) levels, we know the renal tubular damage, and we know how to hold the institution accountable for failing to provide hydration and rest breaks.

The 48-Hour Evidence Preservation Protocol

The moment you hire our firm, we deploy a paralegal-grade investigation. We don’t wait for a lawsuit to be filed to demand evidence. We send a formal spoliation letter within 24 hours of retention to the park, the franchisor, and their insurance carrier.

We demand the preservation of:

  • Multi-angle surveillance footage: Before the 7 to 30-day overwrite cycle begins.
  • Digital Metadata: We want to see if the incident report was “revised” after you left the building.
  • Kiosk Audit Trails: We verify if the waiver system glitched or if the version you “signed” matches the one they are trying to enforce.
  • Maintenance Logs: We look for the 10 weeks of missed foam-pit fluffing or the torn mat that was noted but never repaired.
  • Staffing Records: We subpoena the time-clock data to prove the park was understaffed during the peak hour of your injury.

We use forensic tools like Magnet AXIOM and FTK Imager to interrogate DVRs when a park claims the video “just happened” to glitch at the moment of impact. As the Georgia jury in the Mathew Knight case showed, when 4 cameras “glitch” simultaneously, it results in a $3.5 million verdict for the plaintiff.

FAQ: What Royse City Parents Need to Know

Can I sue if I signed the waiver at the Urban Air in Rockwall?

Yes. In Texas, a parent’s signature generally cannot waive a minor child’s own personal injury claim. Under the Munoz v. II Jaz rule, your child’s right to seek justice is protected even if you signed the iPad at check-in. Furthermore, the Dresser doctrine requires waivers to be conspicuous and use the word “negligence” explicitly. Many North Texas parks use template waivers that fail these legal tests.

How much is my child’s trampoline injury case worth?

Valuation depends on the life-care plan. A Salter-Harris growth plate injury isn’t worth just the initial surgery; it’s worth the next 10 years of orthopedic monitoring and potential corrective osteotomies. National data for serious pediatric fractures anchors in the $500K to $2.5 million range. For catastrophic spinal or brain injuries, results can reach $15 million or more, such as the $15.6 million award for Damion Collins.

How long do I have to file a claim in Rockwall County?

In Texas, the statute of limitations is generally two years. However, for a minor, the clock is tolled until their 18th birthday. Warning: Do not wait. While the legal deadline is years away, the evidence deadline—the surveillance video and the witness memories—expires within weeks.

Why is the insurance adjuster offering us a “Med-Pay” check so quickly?

This is the “Friendly Adjuster” trap. They offer $3,000 to cover your co-pays in exchange for you signing a “simple release.” That release ends your case. Never deposit a check or sign a form from an insurer until Ralph or Lupe has reviewed it.

What if the park says it was my child’s fault for “horseplay”?

In Royse City, trampoline parks have a non-delegable duty to supervise. They cannot outsource their safety responsibility to a seven-year-old. If they allowed horseplay to continue or failed to separate jumping zones by size, the fault lies with the professional operator, not the child.

Why Choose Attorney911 for Your Royse City Case?

Most personal injury firms treat a trampoline case like a garden-variety slip-and-fall. They send a demand, take the $1 million policy limit, and move on.

We don’t.

We know that the $1 million primary policy is just the first layer. We find the umbrella policies, the excess towers, and the franchisor’s additional-insured coverage. We build a Pediatric Life-Care Plan that itemizes every medically necessary cost your child will face over the next 70 years—from physical therapy to vocational retraining.

As client Chad Harris said, “You are NOT just some client… You are FAMILY to them.” That is our commitment to every family in Royse City. We represent the parent at the bedside who is hearing for the first time that their child will never play competitive sports again. We represent the family that is being bullied by a corporate legal team in a Dallas glass tower.

We advance every expert cost. We pay for the biomechanical engineer to reconstruct the velocity of the double-bounce. We pay for the pediatric neurologist to map the TBI. We pay for the ASTM compliance specialist to testify about the monitor ratio. You stay focused on your child’s recovery. We stay focused on the fight.

The park has a risk team. You need an army.

What happened to your child wasn’t a “freak accident.” It was the result of a business model that put margin ahead of safety. We are here to balance the scales.

The Landscape of Trampoline Accountability in North Texas

When you drive through Royse City, past the new developments and the historic downtown, you see a community built on family. The trampoline industry sees that same community as a revenue stream. Chains like Sky Zone, Urban Air, and Altitude compete for those families, knowing that Royse City’s growth provides a steady supply of patrons.

But the industry’s growth hasn’t been matched by regulatory oversight. Texas is one of 39 states with no specific law requiring trampoline parks to report injuries or submit to state inspections. Unlike the Class B inflatable rides in the park, which the Texas Department of Insurance does regulate, the trampoline mats themselves exist in a legal vacuum. In that vacuum, our firm provides the only meaningful oversight.

Every lawsuit we file and every verdict we win, like the $11.485 million Cosmic Jump case, sends a message to every operator on I-30 or State Highway 66: your margin is not more valuable than a Royse City child’s life.
