One second. One bad landing. One scream that changes your family’s life forever.

When your child is hurt at a trampoline park in Houston, the world stops. You are at the bedside at Texas Children’s Hospital or Children’s Memorial Hermann, watching a surgeon explain what a Salter-Harris fracture means for a nine-year-old’s transition to adulthood. You are looking at medical bills that already exceed your deductible. And then, the phone rings. It’s the park’s insurance adjuster, sounding concerned, asking if you’ve had a chance to “look over the paperwork” you signed at the kiosk.

They want you to believe the waiver ended your case before it began. They want you to believe that because you let your child jump, this was just an “accident.”

We are here to tell you that what happened to your child wasn’t an accident. It was the predictable output of a business decision. At Attorney911, we have spent over 25 years making corporate defendants accountable for putting profit ahead of safety. We know why that trampoline bed failed, why that monitor wasn’t watching, and why that waiver isn’t the wall the insurance company says it is.

Our managing partner, Ralph Manginello, has taken on Fortune 500 giants like BP after the Texas City refinery explosion. He brings that federal-court battle experience to every trampoline case we file. Our associate attorney, Lupe Peña, used to sit on the other side of the table—defending recreational businesses and insurance carriers against claims exactly like yours. He literally wrote the playbook they are using against you right now. Today, he uses that insider knowledge to dismantle their defenses.

We are Houston’s dedicated trampoline injury firm. Whether your child was hurt at a Sky Zone in Cypress, an Urban Air in Pearland, a Cosmic Air in Katy, or on a backyard trampoline in Sugar Land, we know the standards, we know the medicine, and we know how to win.

The Houston Trampoline Trap: Why “Safe Fun” is a Multibillion-Dollar Business Decision

Houston is a saturated market for indoor jump parks. From the Heights to the Woodlands, and from Baytown to Sugar Land, there are more than 30 commercial trampoline facilities operating across our metro. Thousands of kids are airborne in Harris and Fort Bend counties every Saturday afternoon.

But here is what the marketing gloss doesn’t tell you.

The American Academy of Pediatrics (AAP) has advised against recreational trampoline use since 1999. They reaffirmed that warning in 2012 and again in 2019. For over a quarter of a century, the highest medical authority in the country has said these products maim children. The industry responded not by making the products safer, but by scaling them to an industrial level.

The commercial trampoline park standard, ASTM F2970, was written by the industry itself to establish a safety floor. When a park in Houston operates with one attendant for 60 jumpers on a Saturday afternoon, they aren’t just “busy.” They are operating below the floor their own peers set. They are choosing to save on labor costs while accepting a known, mathematically certain rate of pediatric injury.

In Harris County, we have seen exactly how a jury responds to this. A Houston jury awarded $11.485 million—including $6 million in punitive damages—against the operator of Cosmic Jump after a 16-year-old fell through a torn trampoline slide onto concrete. The waiver was signed. The park argued the risk was inherent. The jury found gross negligence anyway. That is the largest reported jury verdict of its kind in the United States, and it happened right here.

If you are facing the aftermath of a catastrophic move, you don’t need a generalist lawyer. You need a firm that knows exactly which ASTM provisions were violated and how to prove it. Call 1-888-ATTY-911. Hablamos Español.

The 48-Hour Evidence Crisis: Why You Can’t Wait

The evidence in a trampoline case is engineered to disappear. If your kid was hurt at a park along I-10 or the 610 Loop yesterday, the clock is already ticking.

  1. The DVR Overwrite: Most Houston trampoline parks use surveillance systems that overwrite footage every 7 to 30 days. If we don’t send a formal spoliation demand this week, the video of the double-bounce or the monitor on his phone is gone forever.
  2. The “Revised” Incident Report: Incident reports are entered into digital systems where they can be “updated” later to sanitize the facts. We use forensic digital discovery to pull metadata and timestamps to show exactly when the park tried to change the narrative.
  3. The Kiosk Purge: Kiosk waiver databases often purge version histories on a 72-hour rolling cycle. We need to capture what you actually saw on that tablet before the park “updates” the software.
  4. The Foam Pit Refill: If your child was hurt in a foso de espuma (foam pit), the park will often rotate or refill the cubes within days, destroying the evidence that the pit was compacted below the 8-inch ASTM spec.

Our spoliation letters go out within 24 hours of your retention. We don’t ask the park to save the evidence—we command them to under penalty of sanctions and adverse-inference instructions.

One Jumper, Multiple Layers: Who We Hold Accountable

When we say we “sue the park,” we are actually looking at a complex, 5-layer corporate stack designed to shield the deep pockets. Most firms sue the local LLC and stop. We go upstream.

  • The Operator LLC: The local entity usually on the lease.
  • The Franchisee: The multi-unit group that may own several Urban Air or Altitude locations in the Texas market.
  • The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC. They dictate the training and safety standards. If they fail to audit their franchisees, they are liable.
  • The Corporate Parent: Sky Zone, Inc. (formerly CircusTrix LLC) is parented by Palladium Equity Partners. Urban Air’s parent, Unleashed Brands, was acquired by Seidler Equity Partners in 2023. These are massive conglomerates with nine-figure insurance towers.
  • The Manufacturer: If a mat tore (like in the Cosmic Jump case) or a harness failed (like the Lakhani family case in Sugar Land), we sue the vendor who built the equipment.

We’ve litigated against BP and Walmart. We aren’t intimidated by a private equity sponsor’s fleet of lawyers. We know that the franchisor-on-the-hook theory works—it produced a $15.6 million award in the Damion Collins case against Urban Air, where the franchisor absorbed 40% of the fault.

The Medicine of the Bounce: Catastrophic Pediatric Injuries

Trampoline injuries are biomechanically unique. A child’s skeleton is not an adult’s. Their bones are still ossifying; their growth plates (physes) are made of cartilage that is weaker than the surrounding bone.

Salter-Harris Growth Plate Fractures

At Texas Children’s, your doctor might use the term “Salter-Harris.” This is a fracture through the growth plate. If it doesn’t heal perfectly, the bone may grow crooked or stop growing entirely. What looks like a “broken ankle” at age eight can become a permanent leg-length discrepancy by age fourteen. We build life-care plans that project these costs for the next decade of your child’s development.

SCIWORA (Spinal Cord Injury Without Radiographic Abnormality)

This is a terrifying pediatric reality. A child lands head-first in a foam pit at an Urban Air in the Heights. The CT scan comes back normal. But hours later, the child starts losing feeling in their legs. Because children’s spines are so flexible, the cord can be stretched or compressed even when the bones don’t break. Many Houston ERs miss this diagnosis on the first visit. We work with pediatric neurologists who know the imaging signatures of SCIWORA.

The Rhabdomyolysis Bridge

We are currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. This is the same muscle breakdown we see in kids who jump for 90 minutes straight in a hot indoor park without hydration. If your child had cola-colored urine or listlessness 24 hours after a park visit, that is a medical emergency we understand from the inside out.

Backyard Trampolines and the Attractive Nuisance

Not every injury happens at a park. Houston backyards are filled with Jumpking, Skywalker, and Springfree trampolines.

Under the Texas “Attractive Nuisance” doctrine, a homeowner can be liable if a neighbor child wanders onto their property and is hurt on a trampoline, even if they weren’t invited. If the ladder was left on the trampoline or the gate was unlocked, the homeowner—and their insurance carrier—may be on the hook.

However, many Houston homeowners’ policies specifically exclude trampoline injuries. If your neighbor’s insurance is fighting your claim, we look for a product-liability angle. Did the netting fail? Was there a frame weld defect (a common Skywalker and Jumpking recall issue)? We pursue the manufacturer or the retailer (Walmart for Bouncepro; Amazon for Amazon Basics) if the product itself failed your child.

Why “Hablamos Español” is a Strategic Advantage

Many Houston families are bilingual. If you were presented with an English-only waiver at an Urban Air check-in counter and you didn’t have a fair opportunity to understand it, the waiver may be void.

The Delfingen doctrine in Texas says that contracts signed in a language the person doesn’t read may be unenforceable if there was misrepresentation or a lack of meaningful choice. Our attorney Lupe Peña speaks with Spanish-speaking families directly. We don’t use interpreters. We ensure your family’s voice is heard by the jury exactly as it was at the hospital.

How Much is a Houston Trampoline Case Worth?

We can’t give you a number without seeing your child’s medical chart, but we can look at the data.

  • Catastrophic Spine Injuries: National benchmarks for complete cervical SCI range from $10 million to over $25 million for a child with a 70-year life expectancy.
  • Severe Traumatic Brain Injury: Settlements for permanent cognitive impairment often anchor in the $3 million to $9 million range.
  • Serious Growth Plate Fractures: With future surgery projections, these cases often settle for $500,000 to over $1.5 million.

We advance every cost—the biomechanical engineer who reconstructs the double-bounce, the life-care planner who calculates the next 50 years of medical needs, and the pediatric orthopedic surgeon who will testify in court. As client Chad Harris said, “You are NOT just some client… You are FAMILY to them.” We treat your child’s recovery fund as if it were for our own family.

Frequently Asked Questions for Houston Families

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

Yes. Texas courts are strict, but the Dresser doctrine requires waivers to be conspicuous and express. Furthermore, the Munoz case in Houston dictates that a parent cannot waive a minor’s right to sue for their own injuries in a commercial park. If the park was grossly negligent—like the Cosmic Jump case—the waiver is essentially useless as a defense.

What is a “double bounce” and why did it break my son’s leg?

It’s pure physics. When a heavier person lands just as a lighter person is jumping up, the energy stores in the mat and then transfers. It can multiply the launch force by up to 4x. This is why the industry standard requires separating age and weight groups. If a 150-pound teenager was on the same bed as your 50-pound child, the park violated ASTM F2970.

The park manager said they are a separate company from the national franchise. Is that true?

On paper, yes—they are usually an LLC. But under the “apparent agency” theory, they use the national brand’s colors, logos, and safety videos to get you through the door. We pierce that corporate layer to reach the franchisor and their much larger insurance policy.

How long do I have to file a claim in Texas?

The standard statute of limitations is two years. For a child, the clock is “tolled” (paused) until they turn eighteen, giving them until age twenty. BUT YOU CANNOT WAIT. The evidence—the video, the witnesses, the equipment—will be destroyed or lost within months. Call us today to freeze the case.

Does it cost anything to hire Attorney911?

Zero upfront. We work on a contingency fee. If we don’t recover money for your child, you owe us nothing. We take all the risk because we believe in the case.

Verbatim Houston-area Context & Safety Indicators

  • Major Trauma Centers: Texas Children’s Hospital (Main Campus), Children’s Memorial Hermann Hospital (TMC).
  • Key Corridors: I-10 (Katy), I-45 (The Woodlands), US-59 (Sugar Land).
  • Chain Presence: Urban Air (Sugar Land, Pearland, Humble, Heights), Sky Zone (Baytown), Altitude (Sugar Land, Spring).
  • Local High-Risk Events: Spring Break Galveston crowds, 100°F Summer AC-seeking peaks.

Why the Houston Market is Unique

In Houston, the “Toddler Time” and birthday party markets are dominated by chains like Urban Air and independent operators like Cosmic Air. These facilities often operate in large, converted warehouse spaces along the Hwy 290 and I-10 corridors. The combination of high-density housing in areas like Cinco Ranch or Cross Creek Ranch and the extreme heat during summer months leads to park overcrowding. When overcrowding happens, the ASTM-mandated attendant-to-jumper ratio of 1:32 is the first thing to fail. We’ve seen it, we’ve documented it, and we’ve made them pay.

Building Your Child’s Case in Harris County

Building a case in Houston requires local precision. We know the Harris County dockets. We know which judges handle the “delegation clause” arguments from Urban Air correctly. We know how to subpoena the maintenance logs from an operator in Humble and compare them to the national standards set by Sky Zone corporate in Provo, Utah.

When your eight-year-old comes off a trampoline park court with a shattered tibia and the operations manager hands you a clipboard instead of calling 911, you don’t need a lawyer who “handles accidents.” You need Attorney911.
