“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.” That is how Kati Hill described the moment her three-year-old son Colton’s life changed at a “Toddler Time” session in a Texas trampoline park. Colton suffered a broken femur, and he spent months in a body cast that reached his chest. “We had no idea,” Kati said later, echoing a sentiment we hear from families in the City of San Antonio every week. “We would have never put our baby boy on a trampoline if we would have known.”
We are Attorney911—The Manginello Law Firm—and we represent families who are living through that nightmare. Since 1998, Ralph Manginello has fought for the victims of catastrophic injuries across Bexar County and the State of Texas. With over 25 years of courtroom experience and admission to practice in Federal Court for the Southern District of Texas, our managing partner has built a reputation for taking on the largest corporate defendants in America, from the BP refinery litigation in Texas City to multinational retailers like Walmart and Amazon.
If your child was injured at a trampoline park in the City of San Antonio—whether on Huebner Road, Marbach Road, or at one of the dozens of facilities serving the Northeast and Northwest sides—you are likely being told that the waiver you signed at the kiosk ended your case before it began. You are being told that your child “assumed the risk” of jumping. You are being told that the park is just a franchise and the corporate office isn’t responsible.
The park is wrong. Their insurance adjuster is wrong. And their lawyers are hoping you believe them. The piece of paper you signed at the front desk is not a shield for gross negligence. In Texas, a parent cannot unilaterally waive a minor child’s personal cause of action. We aren’t just a personal injury firm that “handles” these cases. We are a firm that has spent two decades dismantling the defenses trampoline parks rely on. Our associate attorney, Lupe Peña, used to sit on the other side of the table, defending insurance companies and recreational businesses against these very claims. He knows exactly where the holes are in their waivers. He knows the adjuster’s playbook because he helped write it. And as a native Spanish speaker, he represents our City of San Antonio families directly, ensuring nothing is lost in translation when the park tries to pressure you into a quick settlement.
Trampoline injuries in the City of San Antonio are not accidents. They are the predictable output of business decisions made by companies like Sky Zone, Inc. (formerly CircusTrix), Unleashed Brands (the parent of Urban Air), and Altitude Trampoline Park. These entities prioritize margin over the safety standards their own industry authored. When your child is launched into the air by a “double-bounce” or hits the concrete floor beneath a foam pit, it is because a park operated below the ASTM F2970 safety floor.
We are currently litigating a $10 million lawsuit against a major university involving rhabdomyolysis and acute kidney failure—the same catastrophic muscle and organ breakdown we see in crushed-limb and extended-exertion trampoline injuries. We know the medicine, we know the standards, and we know how to hold institutional defendants accountable.
The San Antonio Trampoline Park Landscape: Why Geography Matters
The City of San Antonio is a high-density market for indoor adventure parks. Along I-10, Loop 1604, and I-35, families have their choice of national chains and headquarters-based operators. The Rush Fun Park, headquartered right here in the City of San Antonio, operates multiple locations including Huebner and South San Antonio. Urban Air Trampoline & Adventure Park maintains a massive footprint across Bulverde, Northeast, Northwest, and South San Antonio. Altitude San Antonio on I-10 is one of the largest in the region, featuring a 30-foot climbing wall—the same type of attraction involved in the Matthew Lu fatality in Gastonia, North Carolina. Ground Control on Marbach Road offers a flush in-ground trampoline experience, which changes the injury profile but does not eliminate the risk of catastrophic landings.
When a serious injury happens on a Saturday afternoon at a park in the City of San Antonio, the standard of care is defined by your child’s proximity to a Level 1 pediatric trauma center like University Health. The difference between a full recovery and permanent paralysis is often measured in the minutes between the first scream on the court and the arrival of an EMS unit.
If your family’s primary language is Spanish and you were presented with an English-only iPad waiver at an Urban Air or Sky Zone kiosk in the City of San Antonio, Texas law may provide a specific path to void that contract. Under the Delfingen US-Texas v. Valenzuela doctrine, a Texas court can refuse to enforce an agreement where a language barrier and high-pressure signing conditions prevented a valid contract from being formed. Lupe Peña uses this playbook to fight back when adjusters try to hide behind a signature you didn’t understand.
San Antonio Trampoline Accident Mechanisms: The Physics of Failure
A trampoline is an energy-storage device. When used correctly, it is a tool for elite athletes. When used as a mass-market entertainment product in a crowded park in the City of San Antonio, it becomes a weapon of mass injury.
The Double-Bounce Energy Multiplier
The most common injury at parks like Sky Zone and Urban Air in the City of San Antonio is the double-bounce. This occurs when two jumpers of mismatched weights share the same trampoline bed. The physics are brutal: when a 200-pound adult lands on a bed while a 60-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 are being thrown with force their skeletal system was never designed to absorb.
This is why ASTM F2970—the industry’s own standard—requires “age and weight separation.” When we see a seven-year-old come off a court on a stretcher at a San Antonio park, we look at the attendant-to-jumper ratio. If the park is running three courts with one monitor, they have already chosen to violate the safety floor.
Foam Pit Submerge-Entrapment and Spinal Injuries
Foam pits in the City of San Antonio look safe. They are anything but. The medical literature, including recent studies in Pediatrics by Teague et al. (2024), shows that foam pit injury rates are nearly 1.91 per 1,000 jumper-hours. The mechanism is often a head-first or feet-first submerged landing.
If the foam cubes are compressed or “bottomed out,” the jumper strikes the hard concrete or padded floor beneath. This is how quadriplegic injuries happen. In 2012, Ty Thomasson died at a park in Phoenix because the foam pit was only 2 feet, 8 inches deep when 6 feet were required. In Odessa, Texas, Shawn Parker suffered broken legs because Altitude Odessa used a “dense foam pad” instead of a trampoline base at the bottom of the pit. We look for these engineering shortcuts in every San Antonio case.
Harness Failures and Climbing Walls
The City of San Antonio parks often feature 30-foot climbing walls and zip lines like the Urban Air Sky Rider. These attractions rely on “auto-belay” systems and harnesses. In Sugar Land, a 14-year-old girl fell 30 feet because an Urban Air attendant failed to attach the fall-protection equipment. At Altitude Gastonia, 12-year-old Matthew Lu was killed because of the same harness failure. Altitude publicly admitted “human error” killed that child and permanently removed the attraction. If your child fell from a height in a San Antonio park, we don’t just sue the park; we go after the manufacturer of the harness and the franchisor who mandated the training curriculum.
Why the City of San Antonio Waiver Isn’t a Wall
The biggest obstacle to justice is the belief that a signed waiver ends the story. In the City of San Antonio and throughout Bexar County, the law is nuanced, and it favor families more than the parks want you to know.
The Gross Negligence Carve-Out
No waiver in Texas can release a company from its own gross negligence. In Harris County, a jury awarded $11.485 million against Cosmic Jump after a teenager fell through a torn trampoline slide onto concrete. The jury found that the park had actual knowledge of the defect and showed conscious indifference to the safety of its patrons. That is the Texas standard anchored in Transportation Insurance Co. v. Moriel. If the City of San Antonio park where you were injured knew about a torn mat, a broken spring, or an undertrained monitor and did nothing, the waiver is gone.
The Munoz Rule: Protecting San Antonio Children
For over 30 years, Munoz v. II Jaz Inc. has stood as the definitive guardrail for Texas children. This holding from the Houston 14th Court of Appeals established that a parent in Texas cannot sign away a minor child’s personal cause of action for injuries. While the Texas Supreme Court’s 2025 decision in Cerna v. Pearland Urban Air has made it easier for parks to compel cases into arbitration, it does not mean the child’s claim is barred. Arbitration is just a different room; it is not a loss of your rights. Damion Collins won $15.6 million in arbitration against Urban Air, proving that a skilled legal team can strike the waiver and win the case even in a private forum.
Signer Authority under Tex. Fam. Code § 153.073
In the City of San Antonio’s vibrant family culture, kids often go to parks with grandparents, aunts, or friends’ parents for birthday parties and quinceañeras. Texas Family Code § 153.073 is clear: only a parent or court-appointed conservator has the authority to bind a minor. If an aunt or a friend’s mom signed that iPad at the City of San Antonio Sky Zone, the waiver has no footing as to that child.
Catastrophic Injuries: What We Build for Your Child
Trampoline injuries are not just “broken bones.” They are life-altering medical events that require specialized litigation expertise.
Salter-Harris Growth Plate Damage
A break in a child’s leg is often a Salter-Harris fracture. Because children’s bones are still developing, a break through the growth plate (physis) can result in permanent limb-length discrepancies or angular deformities. An injury at age eight may not produce a measurable shortening of the leg until age fourteen. If your lawyer doesn’t understand the long-tail medical trajectory of pediatric orthopedics, they are leaving millions on the table.
SCIWORA: The Invisible Spinal Injury
Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) is a pediatric phenomenon where a child sustains a permanent cord injury that doesn’t show up on an initial CT scan or X-ray. If your child had a head-first landing in a San Antonio foam pit and was told by the ER that they were “fine” because the scans were clear, but they are still experiencing numbness or weakness, you need an immediate second opinion from a pediatric neurologist.
Exertional Rhabdomyolysis and Acute Kidney Failure
Our experience litigating a $10 million rhabdomyolysis case gives us a distinct edge in City of San Antonio trampoline cases. When a child jumps for 90 to 120 minutes in a hot indoor environment without water, their muscle tissue can literally begin to disintegrate. This releases myoglobin into the blood, which shut down the kidneys. If your child has “cola-colored” urine or extreme muscle pain 24 hours after a visit to a park like The Rush or Airtopia, this is a medical emergency.
The Evidence Clock: 7 to 30 Days
The City of San Antonio trampoline parks operate under a system of evidence destruction.
- Surveillance Overwrites: Most DVR systems at parks like Urban Air and Sky Zone are set to overwrite in as little as 7 to 14 days.
- Waiver Purges: Kiosk databases often purge version history on a 72-hour rolling cycle.
- Incident Report Revisions: The original handwritten report often tells the truth; the version entered into the corporate cloud 48 hours later is sanitized for the insurance company.
We send a formal spoliation letter within 24 hours of being retained. We demand the DVR hard drive, the access logs, and the original incident report metadata. In Georgia, a jury awarded Mathew Knight $3.5 million because the park’s surveillance cameras “just happened” to glitch at the moment of injury. We don’t accept “it’s not available” for an answer.
Liable Parties: Piercing the San Antonio Park Shield
We don’t just sue the local LLC. We trace the money upstream to the parties who actually make the decisions. The City of San Antonio park operator is usually an undercapitalized LLC with a $1 million policy limit. That won’t cover a lifetime of care for a spinal cord injury. We name and discover:
- The Franchisee: The multi-unit ownership group.
- The Franchisor: Sky Zone Franchising LLC or Urban Air Franchise Holdings, who set the training manuals.
- The Parent Company: Sky Zone, Inc. or Unleashed Brands.
- The Private Equity Sponsor: Palladium Equity Partners or Seidler Equity.
- The Manufacturer: The makers of the mat, the harness (Ropes Courses, Inc.), or the trampoline (Jumpking, Skywalker).
As client Chad Harris said about our firm, “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.” We treat your child’s recovery like it was our own. We advance every cost—the biomechanical engineer, the life-care planner, and the forensic economist. We don’t take a dime unless you get paid.
The 60-Angle Tactical Advantage: What Other Firms Miss
Most firms in the City of San Antonio treat a trampoline case like a slip-and-fall. We treat it like the high-stakes corporate litigation it is.
- Was the injury in the cafe? A fall in the snack bar is often outside the scope of the trampoline waiver entirely.
- Did the park follow the internal manual? Sky Zone’s own worker manuals often warn staff to “be aware of the pads”—a warning they never give to San Antonio parents.
- Was the monitor a “staffing agency” employee? If the park used a third-party agency for weekend staff, we find separate insurance layers.
- Did the park’s insurance application lie? If the park represented that they maintain a 1:32 monitor ratio to get low premiums but were running 1:60 on the day of your injury, we create bad-faith leverage against their insurer.
Frequently Asked Questions for San Antonio Families
What should I do if my child was hurt at a Sky Zone in the City of San Antonio?
Your first priority is medical care at a Level 1 pediatric trauma center like University Health. Do not let the park’s manager talk you into “walking it off.” Second, take photos of the court, the padding, and the monitor positions before you leave the building. Do not give a recorded statement to the “friendly” insurance adjuster who will call within 48 hours. Call us immediately so we can freeze the surveillance video before it is deleted.
How long do I have to sue a trampoline park in Texas?
The standard statute of limitations for personal injury in the City of San Antonio is two years from the date of the injury under Tex. Civ. Prac. & Rem. Code § 16.003. However, for injuries to minors, the clock is “tolled” (paused) until their 18th birthday, giving them until age 20. But waiting is a catastrophe for evidence. Witnesses disappear, and video is deleted. The “evidence clock” is measured in days, not years.
Can I sue Urban Air if I signed a waiver in the City of San Antonio?
Yes. Texas courts routinely void or limit waivers that fail the Dresser conspicuousness test or the “express negligence” rule. Furthermore, because Urban Air is a commercial entity, the Munoz rule prevents a parent from waiving a child’s direct claim. Even if a court enforces an arbitration clause, the underlying negligence of the park remains a valid legal claim.
How much can my family get for a trampoline injury settlement in the City of San Antonio?
Settlement values are driven by the severity of the injury and the available insurance layers. A simple fracture without growth plate damage may anchor in the $50,000 to $150,000 range. A Salter-Harris growth plate injury requiring years of monitoring can reach $500,000 to $2 million. Catastrophic spinal cord injuries involving quadriplegia or paralysis range from $5 million to over $25 million nationally. We build a Pediatric Life-Care Plan to ensure the demand covers every year of your child’s adult life.
Why is my child’s urine dark after the trampoline park?
This is a critical warning sign of exertional rhabdomyolysis. It means your child’s muscle cells have ruptured and are poisoning their kidneys. Go to the emergency room immediately and request a CK (creatine kinase) test. This often follows 90 to 120 minutes of continuous jumping in a hot environment. Our active $10 million rhabdo case against UH gives us the medical expertise to prove this was the park’s fault.
Is the foam pit at the City of San Antonio park really safe?
Public evidence suggests many foam pits are unmaintained. If the foam blocks look compressed or tiny, it means they are no longer providing impact protection. The industry is moving toward airbags because foam pits are linked to broken necks and vertebral-artery dissections leading to strokes. If your child landed head-first and has neck pain, do not assume a “clear” CT scan means they are safe from SCIWORA.
What happens if the San Antonio park says the video is missing?
This is why we send spoliation letters within 24 hours. If a park in the City of San Antonio destroys video after being put on notice of a claim, we move for an adverse inference instruction. We tell the jury they must assume the video showed the park was negligent. We also hire digital forensic experts to interrogate the DVR and see who accessed or deleted the files.

When we say “we sue Sky Zone,” what that actually means is we identify the specific operator LLC running the park where your child was hurt, we pull the franchise agreement to identify the franchisee and the franchisor, we trace the ownership through Sky Zone, Inc. to Palladium Equity Partners, and we name every layer we can hold accountable. Because the City of San Antonio operator LLC is often undercapitalized and carries a policy limit that won’t cover a catastrophic injury. The money is upstream.
The parent conglomerate behind Sky Zone, Inc. (renamed from CircusTrix LLC effective Jan 1, 2023; backed by Palladium Equity Partners continuously since 2018) and Unleashed Brands (Urban Air’s parent, acquired by Seidler Equity Partners Feb 7, 2023) hire exactly the same kind of corporate-defense firms BP hired after the Texas City refinery explosion. That doesn’t scare us. We’ve already fought that fight.
The San Antonio Liability Stack: Who is Responsible?
In the City of San Antonio, we identify the full defendant stack for every client.
- The Operator: The Bexar County LLC on the lease.
- The Franchisor: Urban Air Franchise Holdings or Sky Zone Franchising LLC, who mandated the failed safety protocol.
- The Component Manufacturer: The vendor who supplied the torn mat or the harness that failed.
- The Private Equity Firm: Palladium Equity or Seidler Equity, whose cost-cutting demands often lead to City of San Antonio understaffing.
