One bounce. One bad landing. One broken neck. That is all it takes for a Saturday afternoon at a trampoline park in Watauga to become a lifetime of medical debt and permanent disability. You signed the waiver at the kiosk because the line was long and your child was excited. You let them jump because you wanted them to have fun. Now, you’re sitting in a hospital room, perhaps at Cook Children’s or Children’s Medical Center Dallas, watching a surgeon explain what happens when a growth plate is destroyed at age nine.

It is a nightmare Kaitlin “Kati” Hill knows well. As she told ABC News after her three-year-old son Colton suffered a broken femur in a body cast, “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.” Kati’s warning has been shared hundreds of thousands of times because it echoes the silent fear of every parent in Watauga: We had no idea.

At Attorney911, we are here to tell you that what happened to your child was not an accident. It was the predictable output of a system designed to maximize margin at the expense of safety. We are a firm built for this fight. Since 1998, Ralph Manginello has gone head-to-head with corporate giants like BP, Walmart, and Amazon. Our team includes Lupe Peña, an attorney who used to sit on the other side of the table—defending insurance companies and trampoline parks against these exact claims. He knows their playbook because he helped write it. Now, he uses that insider knowledge to dismantle their defenses for families in Watauga and across Tarrant County.

Whether your child was injured at a commercial park in the DFW metroplex or on a neighbor’s backyard trampoline, the evidence is evaporating right now. Park surveillance video is often overwritten in as little as 7 to 30 days. Incident reports are “finalized” by risk management teams to scrub any admission of fault. If you wait, you lose. Call us immediately at 1-888-ATTY-911. Hablamos Español. Our spoliation letter goes out within 24 hours of your call.

The Watauga and DFW Trampoline Park Saturated Market

Watauga sits at the heart of one of the most saturated trampoline park markets in the world. With Urban Air Adventure Park headquartered just down the road in Bedford and Altitude Trampoline Park based in Fort Worth, these corporate giants treat Tarrant County as their primary testing ground. DFW families have dozens of options, from the Sky Zone in Hurst to the Urban Air locations in Southlake and North Fort Worth.

On a Saturday afternoon, thousands of children are airborne in the 76148 zip code and surrounding areas. The industry’s own data, published in Pediatrics (January 2024), reveals an injury rate of 1.14 per 1,000 jumper-hours. In a metro area our size, that translates to thousands of emergency room visits every year.

Most parents believe these facilities are regulated by the state of Texas. They are not. Texas has no statewide trampoline park safety act. There is no mandatory state inspection of the trampoline beds, no required injury reporting to the Texas Department of Insurance (TDI), and no minimum insurance mandate for the courts themselves. While the TDI regulates “Class B” inflatable rides—like the bungee trampolines or inflatable obstacle courses you see at Urban Air—the main trampoline decks are statutorily excluded under Texas Occupations Code § 2151.002. You are jumping in a regulatory vacuum, relying entirely on a sixteen-year-old attendant’s training and a corporation’s internal “safety standards.”

Why the “Industry Standard” Is a Safety Floor, Not a Ceiling

When a park tells you they meet “the industry standard,” they are referring to ASTM F2970. It is critical to understand that this standard was written by the trampoline park industry itself. It is a voluntary standard that establishes a safety floor, and even that floor is routinely ignored during peak hours in DFW.

ASTM F2970 requires specific attendant-to-jumper ratios and age-separated jumping zones. When one monitor is tasked with watching fifty kids on a Saturday evening during a “Glow Night” at a Hurst or North Fort Worth facility, that standard is being violated in real-time.

Furthermore, the rest of the developed world has moved far past the U.S. voluntary regime. In November 2022, the International Organization for Standardization published EN ISO 23659:2022, a mandatory safety standard across Europe that covers design, construction, and operation—including specific requirements for foam pits and airbags. While Sky Zone, Urban Air, and DEFY operate to a voluntary floor, European parks operate to a mandatory ceiling. We hold Watauga-area parks accountable to the highest standard of care, ensuring they don’t hide behind a self-written, voluntary rulebook.

The Physics of the Double-Bounce: Why Size Mismatches are Lethal

The most common catastrophic injury mechanism we see in Watauga trampoline cases is the double-bounce. It is a matter of pure physics. When a 200-pound adult lands on a trampoline bed at the same instant a 50-pound child is pushing off, the energy transfer multiplies the child’s launch force by up to four times.

The child isn’t jumping anymore; they have become a projectile. They are launched at velocities their developing musculoskeletal system cannot handle. This energy transfer is the primary cause of comminuted femoral shaft fractures and Salter-Harris growth plate injuries.

ASTM F2970 and the operations manuals for chains like Urban Air and Sky Zone require strict age and weight separation. When a park in the Mid-Cities allows a teenager to jump on the same bed as a toddler during “Toddler Time,” they aren’t just making a mistake; they are consciously disregarding a known, lethal risk. As we’ve seen in cases like the Flight Deck Fort Worth demand involving a 4-year-old with bilateral Salter-Harris fractures, the “rule on paper” means nothing if the teenager catching your money at the front desk doesn’t enforce it on the court.

The Foam Pit Trap: Soft Landing or Concrete Reality?

Foam pits are marketed as the ultimate soft landing, but they are responsible for the highest concentration of catastrophic spinal injuries in the industry. The mechanism is “bottoming out.” Over time, open-cell polyurethane foam cubes compress and lose their density. If the park does not rotate the foam regularly or maintain the pit depth to ASTM specifications, a jumper can sink straight through to the hard floor.

In Phoenix, Arizona, the 2012 death of Ty Thomasson at SkyPark Phoenix revealed a foam pit that was only 2 feet, 8 inches deep—less than half the industry’s recommended depth. His mother, Maureen Kerley, fought to pass “Ty’s Law,” but in states like Texas with no such regulation, your only protection is the threat of a lawsuit.

We also look for SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). This is a pediatric-specific risk where the spinal cord is stretched or compressed, leading to paralysis, but the initial CT or X-ray appears normal. Many Tarrant County emergency rooms may miss this diagnosis initially. The viral case of Elle Yona, which has garnered over 27 million views on TikTok, highlights the danger of misdiagnosing a vertebral artery dissection or spinal stroke as a “panic attack” after a foam pit landing. We know the medicine, and we know how to prove it.

The Waiver Is Noise, Not a Wall

The first thing the insurance adjuster for a Watauga park will do is point to the waiver you signed and tell you that you have no case. They are wrong.

In Texas, a signed waiver is not an automatic shield. Our firm uses a multi-faceted attack strategy to dismantle these documents:

  1. Gross Negligence Carve-Out: Under the landmark Texas case Transportation Insurance Co. v. Moriel, 879 S.W.2d 10 (Tex. 1994), no waiver can release a defendant from “gross negligence.” If a park knew its equipment was torn or its courts were understaffed and chose to stay open anyway, the waiver is void.
  2. Parental Indemnity (The Munoz Rule): Texas courts, specifically in Munoz v. II Jaz, Inc. (1993), have held that a parent cannot bind a minor child to a pre-injury waiver of their personal injury claims. Your child’s right to recover survives your signature.
  3. The Dresser “Fair Notice” Doctrine: Under Dresser Industries, Inc. v. Page Petroleum, Inc., a release must be “conspicuous.” If the legal language was buried in a twenty-screen tablet click-through and didn’t use the word “negligence” in a bold, contrasting font, it may be unenforceable.
  4. Bilingual/Spanish Formation (The Delfingen Attack): If your family’s primary language is Spanish and no translation was provided at the Watauga park’s kiosk, the Delfingen doctrine allows us to challenge the validity of the contract entirely. Lupe Peña of our firm speaks Spanish natively and can navigate this defense without interpreters.

In Harris County, a jury awarded $11.485 million against Cosmic Jump after a teen fell through a torn slide onto concrete. The waiver was signed. The jury found gross negligence anyway. We believe Tarrant County juries are just as committed to holding reckless corporations accountable.

Multi-Million Dollar Medical Realities: Pediatric Catastrophic Injury

A trampoline injury to a child is not just a “broken bone.” It is a life-altering event that requires a sophisticated damages calculation. We represent parents who are standing by their child’s bed, wondering what the next twenty years will look like.

Salter-Harris Growth Plate Fractures

In a growing child, the growth plate is the weakest part of the bone. A fracture through this area (Salter-Harris Type II-V) can lead to a limb-length discrepancy or angular deformity that doesn’t fully manifest until puberty. Your child might need corrective osteotomies or a decade of orthopedic monitoring. We don’t settle for the ER bill; we build a Life Care Plan that accounts for every future surgery and therapy visit.

Traumatic Brain Injury (TBI)

Whether it’s a “mild” concussion or a severe diffuse axonal injury (DAI), a brain injury in a developing child is a permanent multiplier. We work with pediatric neuropsychologists to document cognitive fatigue, academic regression, and behavioral shifts. A park’s failure to invoke a concussion protocol after a head strike is a choice that can lead to permanent disability—and we make them pay for it.

Exertional Rhabdomyolysis

One of the most under-recognized risks in the industry is “rhabdo.” A child who jumps for 90 minutes straight in a hot, poorly ventilated indoor park without adequate water can suffer muscle breakdown that releases myoglobin into the bloodstream. This leads to acute kidney failure. We are currently litigating a $10 million lawsuit against the University of Houston involving this exact pathology. We know the labs to look for—CK levels exceeding 50,000 U/L and “cola-colored” urine—and we know how to hold the institution responsible for ignoring hydration needs.

Adjacent Attractions: Go-Karts, Ziplines, and Climbing Walls

Modern Watauga-area “trampoline parks” are actually Family Entertainment Centers (FECs). They’ve bolted on go-karts, ropes courses, and ziplines to increase revenue. These attractions often carry even higher risks than the trampolines themselves.

  • Sky Rider Ziplines: There is a documented chain-wide pattern of strangulation by harness cords on the Urban Air “Sky Rider” attraction, including a recent incident in Newnan, Georgia, involving a six-year-old.
  • Climbing Walls Over Concrete: The 2019 death of twelve-year-old Matthew Lu at an Altitude park in Gastonia, North Carolina, occurred when a monitor failed to secure a harness, leading to a fall onto concrete. The park publicly admitted to “human error” and removed the attraction—a classic admission we use in our pleadings.
  • Electric Go-Karts: The December 2025 death of six-year-old Emma Riddle at an Urban Air in Port St. Lucie, Florida, allegedly involved a mechanical surge without driver input.

If your child was hurt on one of these “bolt-on” features, the waiver often doesn’t even mention the specific attraction. We pierce the corporate structure to find the attraction manufacturer and the franchisor. In the Damion Collins v. Urban Air Overland Park case, an arbitrator awarded $15.6 million for quadriplegia, finding a “systemic failure” by the park and its franchisor to implement safety changes.

Identifying the Five-Layer Defendant Stack

When we sue a chain like Sky Zone or Urban Air, we don’t just sue the local LLC. We trace the money upstream to the corporate parent and private equity sponsors. The defendant stack usually looks like this:

  1. Operator LLC: The local business that owns the Watauga-area lease.
  2. Franchisee: The multi-unit holding company that may own several regional parks.
  3. Franchisor: Urban Air Franchise Holdings or Sky Zone Franchising LLC. They dictate the safety manuals and training programs.
  4. Brand Parent: Unleashed Brands (backed by Seidler Equity) or Sky Zone, Inc. (formerly CircusTrix, backed by Palladium Equity).
  5. Component Manufacturer: The company that built the defective net, harness, or go-kart (e.g., Ropes Courses, Inc. for climbing walls).

We find every layer of insurance—primary GL, umbrella towers, and franchisor “additional insured” coverage—to ensure your child’s recovery fund is fully funded.

The Attorney911 48-Hour Evidence Protocol

Successful trampoline litigation is decided in the first few days. While you are focused on your child’s medical care, the park’s risk team is focused on their defense.

We deploy a forensic-grade evidence preservation protocol immediately upon retention:

  • 24-Hour Spoliation Letter: We demand the preservation of native-format DVR footage. We don’t accept “glitched” video or missing angles.
  • Wayback Machine Archaeology: We capture the exact version of the kiosk waiver that was live on the day of your injury, preventing the park from retroactively “updating” their terms.
  • Ex-Employee Outreach: We use LinkedIn and staff reviews to find former attendants who were on shift. They are no longer under the park’s control and are often willing to tell the truth about short-staffing or broken equipment.
  • ASTM Compliance Audit: We retain industry experts to measure foam pit depth and mat tension against the F2970 and F381 standards.

As client Donald Wilcox said, “One company said they would not accept my case. Then I got a call from Manginello… I got a call to come pick up this handsome check.” We take the difficult cases that other firms decline because we have the forensic depth to win them.

Frequently Asked Questions for Watauga Families

Can I sue if I signed the Urban Air or Sky Zone waiver?

Yes. In Texas, waivers are highly scrutinized. They typically do not bar a minor’s claim, and they never bar a claim for gross negligence. If the park violated ASTM safety standards, the waiver is often a speed bump, not a wall.

How much is my trampoline injury case worth?

Catastrophic cases can result in multi-million dollar recoveries. For example, the Cosmic Jump verdict in Harris County was $11.485M. Serious pediatric fracture cases typically anchor in the $500K to $2M range, depending on whether there is a growth plate injury.

What if the park says my child caused their own injury?

Under Texas law, children under seven are generally presumed incapable of negligence. Even for older children, the park has a “non-delegable duty” to supervise and enforce the rules. They cannot blame a child for a danger the park was paid to prevent.

How long do I have to file a lawsuit in Tarrant County?

The standard statute of limitations in Texas is two years. However, for a minor, the clock is “tolled” until they turn 18, meaning they have until their 20th birthday. While the legal deadline may be years away, the evidence deadline—surveillance video especially—is measured in days.

What should I do if the insurance adjuster calls me today?

Do not give a recorded statement. Do not accept a Med-Pay check. These are tactics designed to close your file before you know the extent of your child’s injuries. Tell them you are represented by Attorney911 and hang up.

No Fee Unless We Win

We represent families on a contingency fee basis. That means you pay nothing up front, and we advance every cost of the litigation—from the biomechanical engineer to the accident reconstruction. We take the financial risk so that you can focus on your child’s recovery. As client Chad Harris said, “You are NOT just some client… You are FAMILY to them.”

If your child has been injured at a trampoline park in Watauga, Hurst, Bedford, or anywhere in North Texas, do not let a kiosk signature decide your future. What happened to your child was the predictable output of a business decision that prioritized profit over pediatric biology. We are ready to make them accountable.
