“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.” For Kaitlin Hill, the Texas mother whose story was shared a quarter of a million times, that moment at a trampoline park changed her family’s life forever. For families in the Town of Addison, that scream is the sound of a system failing.

Injured at an indoor jump arena or on a backyard trampoline in the Town of Addison? You’ve likely already encountered the first layer of the defense machine. You were handed a clipboard or an iPad. You were told to sign a waiver before your child could enter the court. You were told the park has “industry-leading safety standards.” And now, with your child facing a potential lifetime of orthopedic monitoring or a permanent spinal cord injury, the insurance adjuster is calling with a “friendly” check-in, waving that signed piece of paper as if it carries the force of law.

It doesn’t.

At Attorney911, led by Managing Partner Ralph Manginello with over 25 years of courtroom experience, we know that a trampoline injury in the Town of Addison is never just an accident. It is the predictable output of a business decision. Whether the injury happened at a major chain like Urban Air near the Dallas North Tollway or a Sky Zone in nearby Irving, the mechanism and the negligence follow a pattern we have spent two decades dismantling. We bring federal court experience and a track record of holding Fortune 500 corporations accountable to every case we take.

If your family is dealing with the aftermath of a bad landing in the Town of Addison, you don’t need an attorney who “handles personal injury.” You need a team that can cite ASTM F2970 from memory, who has memorized the 2025 jurisdictional split on arbitration clauses, and who knows exactly how to pierce the five-layer corporate stack designed to hide the money from your child’s recovery fund.

The Reality of Trampoline Injuries in North Texas

The Town of Addison and the surrounding Dallas-Fort Worth metroplex represent the most saturated trampoline park market in the world. With Urban Air headquartered just down the road in Grapevine and Altitude Trampoline Park based in Fort Worth, our backyard is the epicenter of the industry. The Fort Worth Star-Telegram documented nearly 500 injuries at 21 area trampoline parks over a seven-year period. In a region where youth sports culture—from elite cheerleading to competitive football—is intense, the Town of Addison’s parks are packed every weekend with kids using these facilities for “training.”

Nationally, the data is even more staggering. Approximately 300,000 trampoline-related emergency department visits occur every year in the United States. According to the 2024 Pediatrics study by Teague et al., the injury rate in foam pits for commercial parks is 1.91 per 1,000 jumper-hours. In a high-traffic Town of Addison park, that means a significant injury is a statistical daily occurrence.

The American Academy of Pediatrics (AAP) has been warning parents since 1999 that trampolines do not belong in a recreational setting for children. Yet, manufacturers like Jumpking and Skywalker continue to sell millions of units for Town of Addison backyards, and corporate parents like Sky Zone, Inc. (backed by Palladium Equity Partners) and Unleashed Brands (backed by Seidler Equity Partners) continue to scale their facilities.

In the Town of Addison, families are caught between a multi-billion dollar industry and a regulatory vacuum. Texas has no statewide law requiring trampoline parks to report injuries or submit to state safety inspections. The Texas Department of Insurance (TDI) regulates the bungee trampolines and inflatable obstacle courses under the Class B ride statutes, but the main trampoline decks—where the most catastrophic injuries happen—are left entirely to the operator’s discretion.

Why the “Paper Shield” Fails in Town of Addison Courts

The most common question we hear from parents in the Town of Addison is: “I signed the waiver, so can I even sue?”

The answer is a resounding yes. In Texas, a waiver is not a wall; it is noise. Our associate attorney Lupe Peña previously worked on the other side of the table, defending the same recreational businesses and insurance companies we now fight. He knows which clauses are airtight and which ones are full of holes.

Under Texas law, specifically the Munoz v. II Jaz, Inc. (1993) precedent, a parent generally cannot sign away a minor child’s personal cause of action. While the park may try to use the 2025 Texas Supreme Court ruling in Cerna v. Pearland Urban Air to push your case into a private arbitration forum, your child’s right to seek compensation survives. Furthermore, no waiver in the state of Texas can release a defendant from gross negligence.

Consider the Max Menchaca v. Cosmic Jump case. In a Harris County courtroom, just a few hours from the Town of Addison, a jury awarded $11.485 million—including $6 million in punitive damages—after a teen fell through a torn trampoline mat onto concrete. The park had a signed waiver. The jury found gross negligence anyway. We use that same architecture to build cases for our clients in the Town of Addison.

The Physics of a Town of Addison Trampoline Injury

We don’t settle for the park’s explanation of a “freak accident.” We use biomechanical engineering to prove exactly how the park violated the standard of care.

The Double-Bounce multiplier

The signature mechanism at parks serving the Town of Addison is the double-bounce. When a 200-pound adult lands on the connected mattress bed at the same instant an 80-pound child is pushing off, kinetic energy is transferred through the mat. The child’s launch force is multiplied by up to 4x. The child isn’t jumping anymore; they are a projectile. ASTM F2970 requires parks to enforce age and weight separation to prevent this precise physics, yet in the Town of Addison, we routinely see “toddler time” sessions where older siblings and adults are allowed on the same court.

Foam Pit Compaction

Foam pits in Town of Addison parks look soft, but they are often deceptive. Under ASTM F2970, foam pits must maintain a specific depth and block density. Over time, open-cell polyurethane cubes compact. A pit that hasn’t been “fluffed” or refilled becomes a shallow trap. A jumper entering head-first hits the hard floor beneath with the same deceleration force as diving into a drained pool. This is the mechanism responsible for cervical spinal cord injuries like SCIWORA (Spinal Cord Injury Without Radiographic Abnormality), where the child’s neck is stretched beyond its limit even when the bones don’t show a fracture on an initial X-ray.

Harness Failures and Falling from Height

Adventure parks in the Town of Addison have expanded beyond the trampoline deck. Attractions like the Sky Rider zipline or climbing walls often rely on auto-belay systems. The Lakhani family suit in Sugar Land is a warning to every Town of Addison parent: there, a 14-year-old fell 30 feet because an attendant strapped the harness but failed to attach the fall-protection line. Understaffing at Town of Addison parks means one teenager is often responsible for five or six separate harness stations. When a child falls from that height onto unpadded concrete, the results are lethal.

1-888-ATTY-911 is answered 24/7. If your child was hurt in a Town of Addison park, we need to send a spoliation letter today.

Catastrophic Pediatric Injuries: Beyond the ER Bill

When a child is hurt at a park in the Town of Addison, the medical bills are just the beginning of the damages. We represent families dealing with:

  • Salter-Harris Growth Plate Fractures: Because a child’s bones are still developing, a fracture through the growth plate (physis) at age seven can lead to a limb-length discrepancy that doesn’t manifest until age fourteen.
  • Traumatic Brain Injury (TBI): Cognitive decline and academic regression in a developing brain are often delayed. A Town of Addison child who seems “fine” after a concussion may require special education accommodations six months later.
  • Rhabdomyolysis and Acute Kidney Failure: This is a specialty of our firm. We currently litigate a $10 million lawsuit against a major university involving “rhabdo.” In the Town of Addison, children who jump for two hours in a hot, poorly ventilated indoor park without adequate hydration can experience muscle breakdown that shuts down their kidneys. If your child has dark, cola-colored urine after a park visit, you are in a medical emergency.
  • Vertebral Artery Dissection: As seen in the viral 2024 Miami case of Elle Yona, a backflip can tear the artery in the neck, causing a spinal cord stroke and permanent quadriplegia.

We work with life-care planners to calculate the next forty years of costs for our Town of Addison clients—not just the next forty days.

The 48-Hour Evidence Protocol for Town of Addison Families

The most important work in your case happens before we ever file a lawsuit. In the Town of Addison, trampoline park surveillance video is typically overwritten on a 7-to-30-day cycle. Incident reports are frequently “revised” by corporate risk managers after the family leaves the building.

When you retain us, our first act is to send a 10-section preservation demand via certified mail to the park and its corporate headquarters. We demand the retention of:

  1. Multi-angle surveillance footage (original native files, not lossy exports).
  2. Kiosk metadata (to prove the waiver formation process was defective).
  3. Attendant training logs (most monitors have only 2-4 hours of training).
  4. ASTM inspection logs for the specific attraction.
  5. DVR access logs to see if anyone viewed or deleted footage post-injury.

Our associate attorney Lupe Peña knows exactly where insurance companies try to bury evidence because he used to help them organize it. In the Mathew Knight Georgia case, a jury awarded $3.5 million because the defense claimed their video “glitched” on four cameras at once. We know how to turn that kind of spoliation into a winning verdict in Town of Addison courts.

Why Town of Addison Parents Choose Attorney911

  • Waiver Defeat Expertise: Lupe Peña provides the insider playbook on insurer tactics. We know which defenses they will use in the Town of Addison before they even file their answer.

  • Hablamos Español: Representamos a familias hispanohablantes en Town of Addison directamente, sin intérpretes. Lupe Peña habla con usted en su idioma natal.

Frequently Asked Questions for Town of Addison Trampoline Injuries

How long do I have to sue a trampoline park in Texas?

In the Town of Addison and throughout Texas, the statute of limitations for personal injury is two years from the date of the accident. However, for a minor under the age of eighteen, that clock is “tolled” until they turn eighteen, giving them until age twenty to file. But beware: while the legal deadline may be years away, the evidence deadline is days away. If you don’t preserve the video, you don’t have a case.

What should I do if the park manager tells me not to call 911?

Call 911 yourself. Multiple reports from Urban Air Southlake and other DFW locations suggest that employees are sometimes instructed to downplay injuries or discourage paramedics. These parks want to avoid a documented EMS run sheet and 911 CAD record. Your priority is your child’s health and the preservation of the public record.

Can I sue if my neighbor’s backyard trampoline injured my child in Addison?

Yes. Texas recognizes the “Attractive Nuisance” doctrine. If a homeowner has a trampoline that is visible and accessible but fails to secure the gate or remove the ladder when not in use, they can be held liable even if your child was a trespasser. Most homeowners’ insurance policies in the Town of Addison actually exclude trampoline injuries, which is why we look for product-liability theories against the manufacturer—like Jumpking or Skywalker—simultaneously.

How much is my child’s case worth?

Every case is different, but catastrophic pediatric settlements in the US have exceeded $1 million in multiple documented instances. For a Salter-Harris fracture with growth-plate damage, the recovery must account for a decade of Monitoring. For a TBI or SCI, the life-care plan alone can reach 8-figure totals. We analyze the available insurance layers—from the operator’s primary GL to the franchisor’s umbrella policy—to ensure we leave no money on the table.

What if I don’t speak English and the waiver was only on an iPad?

This is a potent attack vector in Town of Addison cases. Under the Delfingen US-Texas v. Valenzuela doctrine, a Texas court can refuse to enforce a waiver if the patron lacked English literacy and no translation was offered. If you were pressured to sign an English-only kiosk waiver in a Town of Addison park, call Lupe Peña at 1-888-ATTY-911 immediately.
