In Harris County, Texas, the sound of laughter at a birthday party can transform into a life-altering medical emergency in less than two seconds. For families in City of West University Place, a Saturday trip to an indoor adventure park or a neighbors backyard gathering is supposed to be about exercise and community. However, beneath the surface of bright colors and upbeat music at parks across the Houston metro—from Sky Zone and Urban Air to Altitude and the historic site of Cosmic Jump—lies a systemic failure of safety that we have spent over twenty-five years exposing.
We’ve seen what happens when the physics of a trampoline meets the developing body of a child. We have stood at the bedside of children in the Texas Medical Center, just minutes from City of West University Place, watching surgeons explain why a growth plate injury at age eight means a decade of corrective procedures. At Attorney911, led by Ralph Manginello, our mission is to peel back the layers of corporate protection that national chains use to hide the truth: trampoline injuries aren’t accidents. They are the predictable output of business decisions that prioritize profit margins over the safety of the children in City of West University Place.
If your child was injured in a trampoline accident, you are likely facing an insurance adjuster who is already pointing at a kiosk waiver and a park manager who refused to call 911. We are here to tell you that the waiver isn’t a wall, and the “inherent risks” the park talks about don’t cover their own negligence. With federal court experience and a history of taking on Fortune 500 giants like BP, Ralph Manginello and our firm provide the heavy-hitting representation families in City of West University Place need to secure their child’s future.
One Bad Landing: The Realistic Physics of a Trampoline Injury
Imagine a typical Saturday afternoon. You’ve driven from City of West University Place toward one of the massive adventure hubs near the West Loop or over in Katy. The court is packed. Music is blaring. The teenage “court monitor” is looking at his phone or chatting with a co-worker near the dodgeball court. Your seven-year-old is jumping on a bed when a teenager twice his size accidentally crosses the line and lands on the same mat.
This is the “double-bounce,” and the energy transfer is devastating. When a 200-pound jumper lands while a 60-pound child is pushing off, the kinetic energy of the larger jumper transfers through the trampoline bed, multiplying the child’s launch force by up to 4x. The child isn’t jumping anymore; they are being catapulted. The resulting impact on the child’s lower extremities often results in a comminuted femoral shaft fracture or a Salter-Harris growth plate injury—the kind of trauma that requires open reduction internal fixation (ORIF) and years of monitoring.
As Kati Hill told ABC News regarding her son Colton’s broken femur: “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.” At Attorney911, we hear that scream in every case file we open. Whether the injury happened at a major chain like Urban Air or Sky Zone, or a local operator like Cosmic Air, the mechanism of injury was foreseeable, preventable, and addressed by safety standards the park likely ignored.
Why the Safety Standard Fails Families in City of West University Place
The industry operates under ASTM F2970-22, a voluntary consensus standard that the trampoline park industry actually wrote about itself. Even though this standard was designed to be the “floor” for safety, we routinely find that parks are operating into the basement.
ASTM F2970 requires specific attendant-to-jumper ratios, age-separated jumping zones, and meticulously maintained foam pits. Yet, on any given weekend in the Houston area, those ratios collapse under the weight of high-volume birthday party traffic. While Europe has moved toward mandatory safety requirements under EN ISO 23659:2022, the United States remains a landscape where safety is left to the discretion of private equity-backed conglomerates.
Ralph Manginello has spent his career holding these institutional defendants accountable. We know that when a park in City of West University Place violates its own training manual, it isn’t just “sloppy”—it is gross negligence. Our associate attorney, Lupe Peña, brings a critical edge to our practice: he used to represent the insurance companies that defend these parks. He knows exactly how they train their adjusters to minimize your claim, and he knows where the holes are in the waivers they force you to sign.
The Landmark Precedents: Winning in Harris County
When we talk about trampoline injury litigation in Texas, one case stands as the universal rebuttal to the “you signed a waiver” defense. In Harris County, just a few miles from our office and City of West University Place, a jury awarded $11.485 million against the operator of Cosmic Jump.
A 16-year-old named Max Menchaca fell through a tear in a trampoline slide onto the concrete floor beneath. Despite a signed waiver, the jury found the operator was grossly negligent. They found that the park had actual knowledge of the defect and showed conscious indifference to the risk. This verdict, which included $6 million in punitive damages, is the largest reported jury verdict of its kind in the United States. It happened right here in our backyard, and it proves that when we document the truth, Texas juries will hold these corporations accountable.
Further, we look at the September 2023 arbitration award of $15.6 million in the Damion Collins v. Urban Air case. An adult was paralyzed after an attempted flip on a “Wipe-Out” attraction. The arbitrator held the waiver was unenforceable, finding a “systemic failure to bring necessary information to the patron.” Crucially, the franchisor—UATP Management, LLC—was held 40% liable.
At Attorney911, we use these cases to dismantle the defense’s playbook. If you’re being told that your Urban Air or Altitude waiver ends your case, remember that Ralph Manginello has navigated these exact jurisdictional splits. We look for the “systemic failure” that occurred before you even stepped into the park.
The Five-Layer Defendant Stack: We Go Upstream
Families in City of West University Place often wonder who is actually responsible for their child’s medical bills. The park’s risk management team wants you to believe it’s just the local LLC, which likely carries a limited $1 million primary policy. But the money is always upstream. We use a “Corporate Structure Archeology” protocol to identify every responsible party:
- The Operator LLC: The immediate business on the lease in the Houston area.
- The Franchisee: The multi-unit ownership group that controls staffing and local maintenance.
- The Franchisor: Corporate entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings, which mandate the standards that were breached.
- The Parent Corporation: Sky Zone, Inc. (f/k/a CircusTrix LLC), backed by Palladium Equity Partners, or Unleashed Brands, acquired by Seidler Equity Partners in 2023.
- The Private Equity Sponsor: The ultimate source of the cost-cutting decisions that reduced attendant ratios and delayed equipment repairs.
We don’t just sue the park; we sue the system. When Unleashed Brands acquired Urban Air, the Franchise Times headline read: “Seidler Equity Buys Unleashed Brands AMID LAWSUITS Aimed at Kid-Focused Franchisor.” We take that same aggressive approach, piercing the corporate shields to find the insurance towers that can actually cover a lifetime of care for a spinal cord or brain injury.
Catastrophic Pediatric Injuries: The Medicine Families Face
A trampoline injury to a child in City of West University Place is a unique medical emergency. Because children’s bones are still developing, they are susceptible to injuries that adults never face.
- Salter-Harris Fractures: A break through the growth plate. If not treated by specialized pediatric orthopedists at Texas Children’s or similar Level 1 trauma centers, this can lead to limb-length discrepancy or angular deformity as the child grows.
- SCIWORA (Spinal Cord Injury Without Radiographic Abnormality): In children, the neck is so flexible that the spinal cord can be crushed or stretched even if the X-rays and CT scans look “normal.” Late diagnosis often leads to irreversible paralysis.
- Vertebral Artery Dissection: As seen in the viral Elle Yona TikTok case, a backflip into a foam pit can tear the artery in the neck, causing a spinal cord stroke. These are frequently misdiagnosed as panic attacks in the ER until it is too late.
- Exertional Rhabdomyolysis: If your child has dark, “cola-colored” urine, extreme muscle pain, and vomiting 24-48 hours after jumping, they are in a medical emergency. Extended jumping in a hot environment can cause muscles to rupture and spill protein into the blood, causing acute kidney failure.
We are currently litigating a $10 million university hazing lawsuit involving rhabdomyolysis and kidney failure. We know this pathology better than any other firm in Texas. We understand the myoglobin cascade, the CK levels, and the lifetime of renal monitoring your child may require.
The Waiver Is Noise, Not a Wall: Our Attack Strategy
When the park’s adjuster tells you “you signed a waiver,” they are counting on your silence. In Texas, we have several powerful weapons to defeat these documents:
- The Munoz Rule: Under Munoz v. II Jaz Inc., a parent in Texas generally cannot sign away their minor child’s personal injury claim in advance. While the parent’s own claims might be affected, the child’s right to recover survives.
- The Dresser Fair Notice Doctrine: A waiver must be “conspicuous” and use “express negligence” language. If the fine print was buried in an iPad kiosk during a rush at a park near the South Loop, it may not be enforceable.
- Signer Authority (Tex. Fam. Code § 153.073): Was the waiver signed by a grandmother, an aunt, or the parent of the birthday party host? If the person who signed isn’t the legal guardian, the waiver is often void on its face.
- The Delfingen Spanish-Formation Defeat: If your family’s primary language is Spanish and you were forced to sign an English-only waiver without translation, you didn’t form a valid contract. Lupe Peña speaks Spanish natively and handles these cases directly—sin intérpretes.
Ralph Manginello and our team don’t just read waivers; we dismantle them. We look at the metadata of the kiosk. We pull the version history. If the park “updated” the waiver after your child was hurt, we find out using forensic digital tools.
48-Hour Evidence Preservation: The Clock is Ticking
In City of West University Place, the most critical part of your case isn’t the law—it’s the evidence. Trampoline park DVR systems are often set to overwrite in as little as 7 to 30 days. The “incident report” that the manager filled out may be “revised” in their computer system within 48 hours to remove any mention of staff error.
Within 24 hours of being retained, Attorney911 sends a comprehensive spoliation letter via certified mail to the park and its corporate headquarters in Grapevine or Dallas. We demand the preservation of:
- Multi-angle surveillance footage.
- The original incident report and all metadata revisions.
- Staff shift logs and training records for the teenagers on duty.
- Daily pre-opening inspection logs.
- Foam pit rotation records and airbag pressure logs.
Every minute the park delays a 911 call or a refund is a minute they are using to let the surveillance overwrite. We don’t give them that time.

Frequently Asked Questions About Trampoline Injuries in City of West University Place
Can I sue if I signed the waiver at a Houston-area trampoline park?
Yes. In Texas, waivers often fail because they don’t meet the “fair notice” requirement or attempt to waive gross negligence. More importantly, under the Munoz doctrine, a parent usually cannot waive a minor child’s right to sue for their own injuries in a commercial facility.
How long do I have to file a lawsuit in Texas?
The standard statute of limitations for personal injury in Texas is two years from the date of the injury. For minors, the clock is tolled until they turn 18, but you should never wait. Evidence like surveillance video disappears in weeks, not years. Call us immediately so we can preserve the DVR footage.
What is a “double bounce” and why is it dangerous?
It is the primary cause of broken legs at parks. It occurs when a heavier jumper lands while a lighter child is pushing off the mat. The energy transfer can multiply the child’s landing force by four times, leading to catastrophic fractures. ASTM F2970 requires monitors to prevent this, but they often fail to do so.
Should I take my child to an emergency room even if they seem okay?
Yes. Injuries like SCIWORA (spinal cord injury) or vertebral artery dissection can have a “lucid interval” where the child seems fine before a sudden, devastating decline. Headaches or neck pain after a landing should always be evaluated by a pediatric trauma specialist.
Who pays for the medical bills in a trampoline injury case?
We look for every insurance layer. This includes the park’s primary general liability, the franchisee’s umbrella policy, the franchisor’s additional-insured coverage, and corporate parent excess layers. In backyard cases, we look at homeowners’ insurance and product liability coverage from manufacturers like Jumpking or Skywalker.
What if the park says they aren’t responsible because of “inherent risks”?
“Inherent risk” means an unavoidable danger. A teenager on his phone while an adult launches your child is NOT an inherent risk. An unmaintained foam pit is NOT an inherent risk. That is negligence, and we have the expert biomechanists to prove it.
How much is a trampoline park injury settlement worth?
It depends on the severity. While we won’t promise a specific number, national anchors for catastrophic spinal injuries or TBI can reach into the multi-millions. A Salter-Harris growth plate fracture often results in settlements in the $500,000 to $2 million range to cover a lifetime of monitoring and surgery.
Are trampoline parks safe for toddlers?
The American Academy of Pediatrics has said since 1999 that children under six should never use trampolines. When parks market “Toddler Time,” they are inviting an age-inappropriate demographic into a high-risk environment. We treat this as evidence of systemic negligence.
